planning to upgrade first my current pc before buying a new one. unfortunately, the slot for this mobo is agp 8x . now, i've been researching on the net about agp video cards, the 6800 ultra caught my attention but too pricey and some online stores don't have that card anymore. any recommendation on what graphics cards should i get, aside from the 6800 ultra???? hopefully the card that you guys chose will be able to run/play oblivion 4, FEAR, GRAW and the upcoming c&c tiberium wars. i don't expect it to be at the max graphical settings, but i do expect it to run the games above without framing or slowdown.. by the way, does the memory of the card matters?? does it affect the overall performance of the card??
