I think AMD's recent 6 core chip for the desktop market is a decent chip for the price. I still mostly run WCG and they only use CPU at the current time. I have been running a few GPU, but most of that science doesn't thrill me. The money i spend on electricity I feel is better spent on Medical research projects. If its heating season i don't mind putting a few GPU to work as a guy can always use the heat. In the summer time it gets to be to much for me when I'm trying to keep the house cool. The GPU can really rack up the points if thats all your interested in.
