hi i brought a poc a few weeks ago (still waiting for it) and in the antisipation of waiting for it ive been buying games here are the computer specs AMD 64 3500+ 250GB 1GB RAM Nividi 7800 GT BUY! my question is i have just found out that that graphic card isnt the best out on the market! So should i be worried that these games wont work on it now? The games i brought are singles, DOOM 3, UT 2004 (and pre orderd) UT 2007. They are the fasts games i brought. so should i be worried?
