This confuses me. (GPU Question)

$50?
Well don't get a new card then. You'll get a better one second hand for that little of money.

Those old cards you are linking are nearly worthless for most gaming. They aren't a whole lot better than the aging integrated intel 4k series.

edit: OK, not quite - http://www.pc-specs.com/gpu/comparison-versus/1793/328/intel-hd-graphics-4400-desktop-vs-geforce-gt-240
but still take that 50 bucks and either save it for something more useful, or get someone's more modern 2nd hand card they swapped out for a new one and is sitting in their junk drawer.

brand and model of your PSU. I can guarantee you that 6670 can work even with a generic PSU.

The 240 is a much older card, and the 6670 would be better, but I am not sure how much you want to risk your system. What are your current specs?

Both HD6670 and GT240 do not require any additional power connector (as long as you don't buy OCed versions), so your PSU can handle them.

The recommended PSU of 300 and 400 watts is for your entire system. They don't know what other parts you will be running so it is pretty much a guess.

You can get better cards than what you listed while staying in your price range if you are willing to do some research and have some patience on ebay. The GT 240 from EVGA has been selling on ebay for under $20, some as low as $10.

You need to do a search to see if you can find a review that shows actual power usage of the card under 100% load and then do the same for all the other parts in your computer and make sure your PSU can handle your entire system when under a full load. There are websites that will allow you to enter all your system parts in and it will calculate how much power it will draw, but I never found them to be that exact.

If you end up getting a power supply, make sure you do some research first. They can be very cheap and you don't have to spend much money, but you want to make sure you get something reliable since if it fails it can take out the rest of your computer with it.

you be better off saving for this http://www.newegg.com/Product/Product.aspx?Item=N82E16814487114&ignorebbr=1&cm_re=750_ti-_-14-487-114-_-Product.. its faster, more efficient, uses less power and well here http://www.game-debate.com/gpu/index.php?gid=883&gid2=450&compare=geforce-gtx-750-ti-vs-radeon-hd-6670.

i would visit a small local pc shop and see if they can part with a slightly more powerful power supply for you they normally have bins just piled over of them in the back from people who upgrade and will likely part with one for a few dollars if not just hand you one for free, i mean i dont think they are going to just hand you a 700 watt one or anything but they will likely have a handful of 450 watt ones that most current pre-built systems come with,and any extra power will give you a little more headroom especially if your 375 watt is aged at all.

Anyways, first question one has to ask is what do you plan to play with these cards, what resolution will you be playing on and what are your expectations... Because these two definitely are not the best choice for gaming.

Well you should take a look for AMD R7 line, they are really cheap and more recent! You might find an R7 240 for $50 that's very similar to the HD 6670, but if you can wait and save up some more I recommend you a GTX 750 or an R7 260X!

Here is short list of modern low-end cards that you should check:

• R7 240
• R7 250
• R7 250X
• R7 260X
• GTX 750
