I was wondering which processor to choose for a small upgrade on an older computer, currently I have a athalon xp2600 I'd like to put into another spare parts computer to sell in order to get rid of some spare parts in my basement. The computer I want to put the new processor into is a Gigabyte Nforce 2 Ultra. Should I go with a xp 2800 mobil processor or a sempron 3000 processor at 2 ghz. both are socket 462 and I don't see how the sempron can really outperform the xp 2800 am I missing something or is there a place to buy a motherboard combo with an xp 3000 under $125? Thanks for any help
