I have a P4 2.6 GHz (800 MHz FSB ? overclocked to 3.1 GHz) on an 865PE MB and am trying to figure out if an upgrade is worthwhile. I desperately need more RAM and plan to buy a new video card (currently have GF4 Ti4200) for DVI out and Vista support. Since my MB doesn?t support PCI-E or DDR2 RAM, I am wondering if I should just swap out the MB and processor while I?m at it so I don?t put more money into DDR1 and an AGP card. I don?t use the system for gaming at all, but I do use it for DVD encoding. If I did upgrade, I?d be looking at spending only $200 or so on the CPU and MB, so I certainly wouldn?t be getting the latest and greatest? Is it worth upgrading the CPU and MB while I spend $ on RAM and video, or will I not see much of a speed increase for that amount of money? Any advice is appreciated.
