Dual core is well worth it, an X2 3800+ performs just as good as a 3200+ in games infact probably slightly better, dual core games will be here soon so why buy into something your going to have to upgrade again come early/mid 2006? I was using single cores for way too long, infact my 3000+ at 2.7GHz feels dirt slow compared to my X2 3800+ at 2GHz, I can just feel the bottleneck when using a single core for anything, dual core or bust.
