Good GPU for games

for about 30-60$ more (or wait for sales) you can get a 660 and can max out most modern games at 40fps

edit: most of the more graphics intensive games like bf3

GTX 660ti is the best ratio perf/price around. Stay away from AMD cards (terrible drivers, bad performance on newer games and higher failure rate)

AMD HD7890

i still own a 9500gt 1gb and it works quite well even with the newest titles :)

Yeah, a decent card will run you around 300 to just under 400. The low end cards are just that, low end. Also, the top of the line cards are always a TERRIBLE idea because their power/cost ratio is stupidly out of sync with the mid-high range cards of the same manufacturer. eg. 680 is about 500 bucks, 670 is about 370 bucks, 680 is about a 5-8% increase in performance for a bit more than 30% increase in price. Whereas the 660ti is about 330 or 340 and the performance difference in a 660ti and a 670 is (depending on the game) anywhere from 10-35% increase. You do not buy a new card every year I assume, so why not just get a good card to start with and not cripple yourself with such a low budget.

With that money your best bet will be either Radeon HD 7870 or GeForce 660. If they cost too much for you go for Radeon 7850, GeForce 650 Ti is much slower. Manufacturer wise I would sugest Gigabyte as their cards have very good coolers and often come with little overclocking done.
Take a look here to decide which one of them depending on what games you play/want to play. Also you will most likely get one or more free games with your card, it should be Far Cry 3 if you choose AMD or Assassins Creed 3 for Nvidia.

GTX 660.... NOW!

Get a HD7870. 660 is terribad compared to it's ancestors.
