I would spare around $150 compared to the i7 platform, and still be able to do a Radeon HD 5870 Crossfire when the cards come out. Someone knows how much performance I would lose regarding multi-GPU gaming using the Phenom processor? |

Theres some indication, though I believe the Phenom 2 3.2 would be about as fast as the 3.33Ghz example, especially once you tweaked the performance a little higher though its probably slightly slower with DDR2, DDR3 should give it the edge here.
If you only go with two cards your CPU overhead will be lower and you can achieve better performance with less and achieve better scaling than with 3 GPUs and a faster CPU. That third GPU really doesn't seem to be worth it from a cost perpective. Sure it looks really cool, but its definately not going to give you the same bang vs buck.
@Vetteman check out www.techreport.com, they have excellent builds up every month.
Tease.
