Software Windows Server 2003 R2 as a Workstation now migrated to W10 with regrets.
AGP X8 = PCIe 2.0 x4

That equation requires that BOTH the chipset AND the GPU are running PCIe v2.0

If either or both of them are still PCIe v1.1 then AGP x8 = PCIe x8.

Actually, AGP x8 is about 10% faster than PCIe x8 for GPU tasks (One way communication). A small number, therefore moot.

I dont think Tweaktown lied... I just think they were very quick to point out how slow the p45 is.. There is also a chance that the p45 board they used simply needed work and didnt handle the DDR3 bandwidth very well..

You might be right, but I think the key to good XF performance is to use P45,X38,X48 and 1 gig cards, cause even a 4850 1 gig will beat a 4870 512 at hi-res on some games.....probably Crysis, Grid and maybe StalkerCS.

Isn't the comparison supposed to be between PCI E 2 x8 and PCI E 1.1 x16?
