Numbers are true based on this article at Guru3D "Core i7 Multi-GPU SLI Crossfire Game performance review" but THG's review is a better proof because there is a Phenom 9950 in too and we can extrapolate Phenom II numbers with it, just here "Core i7: 4-Way CrossFire, 3-way SLI, Paradise?
".


Moreover numbers seeing in HardOCP are impressive but the big picture is clearly inflated because Far Cry 2 is the game where there is the most difference in performance between AMD and Intel. About 20% difference clock for clock where other games show like 5% difference in average.
If a review with Tri Sli, will use UT3, Crysis, COD4 or whatever other game, i7 will still dominate easyly but difference between Deneb and Yorkfield will be much more tiny. The big issue of this review is that using ONE game to draw a conclusion is quite stupid.

Moreover based on Savantu's link, Crysis test on HardOCP is false because between 2GB and 4GB it show that there is 20% difference in framerate at 1280x1024. We can suppose that at 800x600 like on HardOCP Phenom II numbers might be 20% better maybe more.
