Does GPU brand matter to you when buying if they're doing the same thing or just price?

Depends on which shop is selling them, what the warranty and support is like, what the conditions are if a defect happens (send it in to Asia or local office or retailer for example)
If there is an office or importer in my country the lesser known brand will be considered otherwise I'll stick to the Asus, MSI or whatever.
And then you have to look at each indiviual model. Just because a partuclar brand has a good rep doesn't mean their stuff don't have faults.

It actually does, but not as much as many would want you to believe. The two important aspects are the factory overclock (to a lesser degree now, that overclocking does not void warranty any more) and the cooling system. There can be easily 10-15 °C difference between brands on the exact same chip.

cheapest please <3

depend on my budget and the brand itself. if too many users complain about that brand, i would save my money to buy the expensive one later (still, im only choose the one that i can afford XD). so, do some research before you buy.
its better to add another 100$ rather than buy a new one right? cause sometimes cheap brand have a problem with heat / noise (i dont really mind about the noise). but the heat problem, its crucial.
*EDITED. voted A. cause i like cheap thing XD

Well I mean, just check out reviews before buying. Unless googling it shows that there's common issues with a particular brands version of a card it's unlikely to cause a problem. Where you buy it is more likely to determine any hassle you have with returns and so on than what brand it is, so that's a more important consideration.

I typically decide on a card model first, then I just sort by price and typically the cheapest one ends up being the one I buy. The difference to get one of the more famous brands from there is rarely more than 10 bucks or so though, so if you're concerned that's usually an easy step to make. the GPU is one of the three areas in a computer build that should take up the bulk of the budget after all, so it's worth increasing spending there and save elsewhere.

I usually go for the cheapest that provides the same GPU model, unless they have some really bad press or reviews

id lean to yes it matters, in that Id at least have to feel comfortable that its a reputable brand. I dont care if its the most expensive best-named brand out there, but i wouldnt buy from some unknown nigerian company or anything.

Personally, I favor the more expensive brands, though I don't criticize people for trying to save money. Part of it is that upgrading my GPU is more a question of "am I going to feel like I overpaid?" I'd probably weigh things differently if upgrading meant an actual change in my spending, like my eating ramen for months to come or not being able to buy games to play on the new card. Part of its that I tend to buy only on a deep sale, so the price difference seems to be less and the many relatively small factors add up, death-of-a-thousand-cuts style.

• Warranty/returnability - this has saved my bacon, so it's a fairly big factor.

• Noise - also a fairly big factor for me, and back when I was deciding on a GTX 760 card, it was down to ASUS or MSI (went MSI, great card).

• Features - differences are few on GPUs compared to motherboards, and tend to be found more in the higher-end cards, but even at the 1060 level, ASUS has RGB lighting, an extra HDMI connector (good for a VR headset or TV out), and a 4 pin fan header that lets the card control an off-board fan pointing at it (if you've got integrated fan software, it's not a big issue, since it can read the GPU temp and control any number of fans based on it, but I think it's a neat feature and gives you another cable routing option).

• Aesthetics - appearance varies, but I tend to like the look of higher-end boards, a clean backplate, etc., so this counts for a few bucks in my loose arithmetic that goes into weighing different features. Whether you're dealing with an open/windowed case can be a factor here, too.

• Resale - you're never going to get back what you put into a card (with very rare exceptions - I've seen a few cases of breaking even on great buys with GPU market volatility), but it's going to be easier to sell an ASUS or MSI for the same price (or a bit more) than the average price on /r/hardwareswap or some other marketplace than a Tingyao. Time can translate into money, especially if the card is on a downward spiral when you're looking to upgrade. Even if it ends up as a hand-me-down, I'd rather pass along an ASUS or MSI board to a friend or family member than some off brand.

• Performance - while I'll be seeing a significant improvement in performance anytime I am seriously looking at an upgrade, my decision to take that plunge is going to be based on in-game performance, either my favorite game at the time or benchmarks on a game I'm planning on getting. If the performance difference of the overclocked brand name card beats the off-brand one, that may mean I delay my purchase until the next game that I get that's more demanding, which may be months later. Again, time can translate into money.

• Reliability/peace of mind - I honestly don't know how much longer my current card (an EVGA 980ti Classified edition) might last compared to a 980ti from Colorful. The odds are they'd both last longer than I'll be using the card. However, if there is a difference and it fails off-warranty, it's a few hundred bucks to replace it and no residual value in the faulty card. Divide the cost by the delta in the probability of failure and there's some dollar amount there - I don't know how much, but this would be the 7th factor. Even if each pro only added accounted for $5-$10, that can put a more expensive card's value above the cheaper one, on top of the subjective satisfaction of having a nicer card as opposed to a sense that you compromised on one of the most expensive parts of your gaming rig.

However, $300+ is a lot to ask for something that is just used for gaming, especially when your old GPU might still be able to play everything at a lower resolution and quality settings, so I don't begrudge anyone looking to save money up front. Ultimately, the gauge on whether one card's a better choice for you is how you're going to feel about it after the fact, rather than some calculation used to estimate the value objectively. That doesn't make these factors meaningless - they are factors in whether you feel satisfied - but the overall sense of value you have about the card as a purchase is going to have a significant subjective component, outside of any attempts to dissect the value.

It does matter more than we think. Most of the time we look at the temps cause the cooling solution is one of the main features, but what about the internals? This guy does an analisys of the PCB components:

He checked most of the RX-480s and for me It was a surprise that the Gigabyte components were not the best since I've always trusted this brand on the motherboard side. The winners are the Asus Strix and Sapphire Nitro, premium quality components that will give the graphics card a better "lifespan".

This doesn't mean that a specific brand can't messed up. It all comes to each model, this is why HW reviews are pretty good but sometimes It's hard to find a really in depth analisys.

Like others said above, good customer support and RMA is really important. It doesn't matter if your card has great quality if you're gonna struggle with the company because of a faulty component (one of the fans, coil whine, artifacts etc).

My advice as they already told you here, do the most research you can on the model you want. Everybody wants a die hard graphics card, even more if you're on a budget.

Here is the video for the Asus GTX 1060:

I do prefer Nvidia GPU's but if an AMD GPU is much cheaper i'll get that one (not really seeing it atm though). I'm an Intel fanboy though and i'll probably never get an AMD CPU , atm they're better value but it probably won't take long for Intel to dethrone them again just like a few years ago.

always go for asus for the same price

Never heard of Colorful or TINGYAO. That said, I always stick to MSI, Asus or Gigabyte. Would go for Elsa or Zotac too.

It depends on the implementation if it's custom or reference. If custom, then the manufacturer makes a difference, otherwise for reference cards, it's the same crap with a different brand. So, in other words, unless there's a custom implementation then it makes no difference.

i checked benchmarks and temperatures of the graphic cards and their customer service. these are the ones who matter for me. anything else is not important.

I recall my vote, I'd not buy shit that has no website!

Brand, aside from other factors listed by LittleBibo1, matters to me. I am more likely to buy from a company I had a positive experience than a new company that I never bought from. The opposite is true as well. I will try a new brand if the one I usually buy from has a streak of inferior products. No one should place trust, as the expression goes "the brand I trust", because each product should be individually judged based on quality. Even if MSI, for example, produces three quality laptops in a row does not mean the fourth laptop will be as valued as the previous laptops. To have mutual, optimistic, yet cautious relationship with the brands a person buys from is healthier to the wallet than blatant loyalty.

I voted B.
