ADDITIONAL COMMENTS: My old card is dead and I have to buy a new one. As I don't want to upgrade other components till September 2011, I'm afraid that I may face some CPU bottlenecks with a new card... I would like to know if it makes sense to buy a GTX 460 with my old CPU? Or should I buy a less powerful card like GTS 450, 5750 or 5770?
Thank you for your time and answers

The GTS 450 isn't the best card to buy and ATI is op atm but at hopefully their prices will sink soon. The GTX 460 is one of the best bang for buck cards out at this time.
Either a 150$ 5770, or get a 220$ 460 1gb. I would go with the 460, you could get a 768mb version, their cheaper and will still give you better performance then what your 7800 could ever do.
Notice: With that resolution you'd be fine to buy either a 5770 or the 460 768mb and play games on high with more than 30fps.
