I currently have a P4 2.8C @ 3.5GHZ, 250MHZ FSB with 1GB Corsair PC 4000 Ram, ATI Radeon 9800PRO 128 @ 425/365, Abit IC7-G motherboard etc.. and wanted to know if upgrading to a X850 PE, X800 PE or X800XL (either of the choices) would be a wise decision or not. I'm just wondering if these video cards would be too powerful for this system or not and whether or not I should upgrade the system completely before upgrading to the next video card. (I'm also considering if it ever comes out the ATI video card with 512MB, 24/32pipelines etc.)
