I have a P4 3.4 and a ASUS P5GV-MX mobo with 2 gigs of DDR 400, ATI X1950 Pro 256 PCI-Ex16 and I like gaming. It has worked pretty well until I played the COD4 demo. I got such low FPS, like 8-15 when action became high. So I thought that I was going to be very happy with buying a high end card for gaming and went ahead and ordered a XFX 8800GTS (G92) 512 PCI-Ex16 card. Well my new card has not arrived yet and I was just in my Catalyst Control Center and noticed that the x16 bus is only running at x4 . I was very alarmed so I went to the ASUS website and found that the board I have has a x16 bus in x4 mode. I really feel stupid for not realizing this before I spent so much on a card that can't be used to it's full potential with the mobo I have! I wonder if I can still install it and it will give me good enough FPS to play COD4 until I can afford to upgrade CPU, mobo and ram?
