Hey guys, I'm wondering what do you think is the cheapest graphics card that you can play games with? I need to recommend one for my friend, and want to find the cheapest one that can still play games. It'll just be dropped into a 2008-2009 Dell computer which is why it can be cheap, I'm not sure any of the specs from the computer, but it's a basic desktop computer. Right now the only game I know he'll be playing on it is World of Tanks. So far the cheapest card that I think will work fine on it is the PNY GTX 640 for $58.99, or the XFX 6570, which of those two do you think is better? Again I know nothing about his computer, he just said it's a Dell and he'll get it out next week once he gets through all the stuff blocking it. After that I'll be able to see if it can even take a graphics card, and if the PSU can support it
