My dual XP 1800 system is getting long in the tooth, the main vid card of an ATI AIW 7500 is getting old. It is good for capturing tv, but I would like to play UT04 with better settings and no choppiness. I was thinking a AIW 9600 128mb 4x/8x would do me since they are around 100 bucks and I could keep basically my same capture interface and everything. My board (Tyan s2460) only has a 1x/2x/4x slot, so will a 4x/8x card work in it?
