I looked up the CPU support list for my mb and, supposedly, it will support up to a 2600+ with the 266 mhz front side bus. How much of an improvement would this be? I also have 512mb of pc2100 DDR and an ATI 9800 Pro. I know this sounds like a pretty stupid question, but I'm trying to decide if I want to do this now, or wait 9-12 months and just build a whole new system. I figure it will cost me about $80 to do the upgrade, and hopefully I will be able to put off building a new system a little longer. Thanks for the advice.
