I have a Asus P4R800-VM mobo, bought new video card and having problems. My new video card is ATI Sapphire X1650 Pro 8X APG 512mb DDR2 memory, I have a Intel P4 2.8 Prescott pcu, 4- 512 memory sticks, a cd rom drive, DVD RW Drive and so on. I want to buy a another mobo that will handle the stuff I have now with the new video card. Anyone knows or has one that is working well for them please let me know, make and model#.
