Recomended video card for games this 2010?

my video card screwed up dunno why last time i play is lead and gold and at midnight game hangs so i should restart then i can't open any games so i decided to sleep but in the morning when you 1st boot your computer the words written there was purple i think it's damage and it can't boot your windows as long as the nvidia driver is installed can it still be repaired or i need to buy a new one?|||I'd recommend the nVidia GTX260 or better for most games, the GTX275 or 280 for very power-intensive games on high resolutions (1920x1200 or larger)|||ATI Radeon HD 5870 is just what you need, if u have tried this then try Nvidia GeForce GTX 295
