I'm trying to figure out what's the beter buy, a Q9450 Quad 2.66ghz Yorkfield (12mb cache) vs. a E8500 Duo 3.16ghz (6mb cache).... The quad's about $60 more, I was going to go the Quad and now am reading the 3.16 duo will kill the quad 2.66 in most things... I'd be using the cpu for light multitasking, but most of the time just downloading, surfing web and listening to music..... what's the better buy??
