Graphic card(new PC build question)

More VRAM does not mean more performance. Just more memory to load stuff. I'd recommend the 760, although I don't know anything about Palit's reputation. The 280 is a good option as well, and Sapphire has a very good reputation. Oh, and avoid AMDs 200 series cards with stock cooling.

Why a 1000W PSU?

The 280 is better than the 760, go for that.

I'd say spending $200-250 on a GPU is way beyond a budget graphic card. I usually aim to spend about $100, for which you can get great performance for a great price. But I also never buy games within the first year of release. I think gaming is a hobby best done cheaply, and its quite easy to do.

"budget graphic card" twice as good as mine, while i'm playing most games on ultra ;D

Get the R9 280 or even better R9 280x.

i7-4770 and a "budget card" don't mix very well unless you want to upgrade in the future. And if its a non K (i7-4770K vs i7-4770) and you don't want to overclock, don't get a Z87 get H87 mobo unless it has some features you really want/need.
Also a 1000W PSU is overkill, unless you want to upgrade in the future or plant to SLI/crossfire.

Vram does not effect you in any way unless you have multiple monitors being set up. You don't need 1000W maybe like 600 or even 550. Try getting r9 280/280x.

The R9 270X is enough for a budget computer.

Go with the Sapphire R9 280 3GB DDR5 OC , that Palit brand is total poop...

And wait what? 1000 W PSU? extreme waste of money and completely unnecessary...!

750TI can be had incredibly cheaply (120 bucks from newegg at times) and due to its insanely low power usage you can also skimp on the PSU's wattage.

1k PSU is def overkill. Same for the i7 unless you actually have need for it like video encoding or got a great deal on it. You say an "everything" PC, but if you are going for a gamer focused PC, an i5-4690 or equivalent would certainly work well enough.

Sapphire R9 280 3GB DDR5 OC > GTX 760 > R9 270X, with 3Gb is more than enough, I would say the ideal, minimum should be 2Gb, you won't get more performance with an R9 270X with 4 vRAM, it's not the way it works, more vRAM doesn't increase performance, you will practically never use more than 2Gb anyways.

Also for what you're planning to buy, "budget", is not the correct word because your computer is not cheap xd, your computer will end in mid-high range, also you don't need and i7, get the best i5 without the "K" if you won't Overclock you don't need the one with the "K", you won't get more performance from an i7 so it's useless spending more money on it, and you don't need a 1000W PSU, just get one from 650-750W from Corsair, also you don't need more than 8Gb of RAM unless you are making videos, for gaming 8Gb is enough.

I suggest getting an i5 instead if you're just gaming on it, and stick with just 8gb of ram. With that, you have a bit more cash to spend on a better GPU.

Th gtx 750 ti is so awesome and you don't need to connect to the psu so it does not consume too much power and it stays cool and you will probably be able to play most games on high- ultra on full hd on most recent games

Edit: and i believe it's the cheapest from all around 150-160$ and i found how much it consumes 60 W

The higher on the table, the better. If they are on the same tier then they are roughly equivalent.

Thats far beyond budget chategory card, budget is around $100,

So, I am in the same position right now wanting to upgrade my old GTX 560 TI.

The AMD 280 is probably the slightly better performance choice, while the NVIDIA is pretty much the same (a little bit (!) slower), but is from NVIDIA. This means better performance in some scaling processes.

I would probably take AMD, because of 3gb RAM

Also: http://versus.com/en/nvidia-geforce-gtx-760-vs-amd-radeon-r9-280

760 is way slower than 280... and is slower than 270x too.
I can't really understand why so people don't research in a proper forum like overclockersnet or linus tech tips, toms hardware's, the tek, tech of tomorrow, pcper, etc etc etc more than a thousand great reviewers that really do review and overview...and most of them try to cover it for gamers. So why would anyone seek for advice about hardware on a gaming forum. it don' make sense to me. almost always a nonsene PSU , with a nonsense amout of ram, with a too good cpu for a crap gpu, or too crap cpu for a great gpu... why people NEVER want to read about it in a proper place ... and read pages and pages in a forum like this...

The worst is most of people never tried what they say and probably never read about ... or have read once and can't remember numbers so ... well
I know I'm too upset about it.. but I see this kind of thing on facebook, on twitter, here everywhere... D: I needed to put it all out of my chest. sorry;

SAPPHIRE R9 270X 4G GD5 OC VER is better

280 vs 760 benchmark 7950 boost = r9 280

I suggest the Sapphire R9 280 3GB DDR5 OC available to your retailer, it's way better than the others and you don't have to pay shipping.

I saw you chose i7-4770 instead of 4770K so I guess you won't OC anytime soon. Then I'll choose the Shappire R9 280. IMHO Shappire is the best brand for R9 graphics cards.
Gigabyte is awesome for GTX cards. I've got a Gigabite GTX 760 and it's an awesome beast, a Gigabyte motherboard (very good) and a Gigabyte mouse/keyboard combo wireless pack (pretty shitty, the box says 10m range but it can't even reach 5m u.u)
But for graphics card from the R9 series I heard bad things about Gigabyte so I won't choose the Gigabyte R9 270X, even if it has got more VRAM.
I never ever heard about Palit.
