Those PCIe 2.0 vs 3.0 benchmarks apply to current gen cards (HD7000 and gtx600 and prior)  I am fairly certain that someone with Z67 board and sandy bridge would be running in to bottlenecks with a dual Titan sli running pcie 2.0 8x8x. 3-4 years down the road when a single card can offer dual titan performance, pcie 2.0 may no be enough. Also since steamroller is using AM3+, there is no reason why he cant upgrade to that in a year or two...

If money was of no concern, Id definetly say go for fx 8320 (not 8350) and a beefy water AIO cooler and get it to 4.8 Ghz...but in a build hes putting together, I dont think its worth 50 bucks more.

Oh god. I've ran tests with my Triple Radeon 7970's with PCI-E 2.0 against 3.0, there was no difference outside of compute. None, nada, nil, with the rate GPU's are advancing these days, it will be a long time before PCI-E 2.0 ever becomes a limiting factor, by then it would be time to overhaul the machine anyway.
People still drop high-end cards into Socket 775 (PCI-E 1.0 16x = PCI-E 3.0 4x) motherboards without a problem or massive performance impact.

PCI-E 2.0 16x = PCI-E 3.0 8x in terms of bandwidth.

Also, don't hedge your bets on Steamroller, it hasn't been confirmed to be coming to AM3+, AMD may release a new socket, A-la. AM4 possibly requiring a new Motherboard.
