Between those 2 the X2 6000. You would have to get a 8750 to be close in a Tri core. Then again you could get a 9550 for close to what a 8750 cost. Did I confuse you even more? The prices on the Tri and Quad AMD are all screwed up right now. I think the only one I like is the 9750 95Watt model right now, but they are hard to find. And they are selling the 9850BE cheaper than the 9750. Go figure.
