I'd be abit skeptical about the sempron 3000+ from ebuyer, as ebuyer are reknowned for poor listing descriptions. Seeing as i cant find any other retailer with a sempron 3000+ for comparison and even amd dont directly specify that exits on there main pages it just appears under processer prices. (

As i was to believe all desktop semprons so far have 256l2 cache, and only the 3100+ (skt754) has sse2. The rest DO NOT have it. Btw they're built on a 130nm process, which is inferior these days, intel have been on the 90nm for a while now, amd are just making in roads to 90nm, and ati & nvidia are begining to use 110nm (the smaller the better)
