But furthermore i can say that its very rewarding to buy a small nvidia-graphics card. Im a ATI-Fanboy, too, have a HD5850, had lots of problems. At the moment the linux-drivers are very good, but still some problems dont get better. Then i found, that i had an old Asus mainboard with a core 2 duo on it, and i decided to create a second pc out of it. My GTS250 cost 30? on ebay, i paid 40? but for a good AMP! model with guarantee. I made a list of nvidia-models with price in ebay: GTS 450 -> -3% 45? -> only model, which i CANNOT! suggest GTS 250 30? GTX 260 -> 14% 40? GTX 280 -> 20% 50? GTX 460 -> 41% 80? (but if youre lucky 60-70) GTX 560 -> 80% 120? GTX 470 -> 96% 110? GTX 570 -> 128% 140? GTX 480 -> 142% 160? GTX 580 -> 155% 260?
