Generally, most people are not going to run into problems at 10C below TJmax, even with a fairly substantial OC, at least not within the typical lifetime of a chip for an enthusiast, but the point remains that you can easily run unsafe settings without causing the CPU to throttle or shut off.

True, although Intel are usually a bit conservative with it in my experience.

Wrong. HD7970s only have 500MB/s on the CFX interconnect, they need a lot more bandwidth to share data fast enough and 8x/8x PCIe 2.0 actually becomes a limitation with HD7970 CFX. Single card? No problems. I've heard multiple users with HD7970s saying that going from Z68 to X78 (8x/8x to 16x/16x, PCIe 3.0 on X78 notwithstanding) netted them not only slightly more FPS, but a much smoother game. Reviews don't usually show smoothness, just fps. You can get FPS in the hundreds but still have a stuttery game.

2.0 x16 is no longer good enough for current-gen cards:

*Snip*

That first graph is interesting albeit useless... Those numbers mean nothing, and its multiplayer.

That 2nd graph is well known. Everybody knows 3.0 is only useful with 3 or more gpus.

i got to say game smoothness feeling or whatever it may end up be called is one aspect that is probably hard to quantify and may take a while since issue arise after about 3 hour of gaming or so

For multi GPU Ivy looks much better than Sandy, but doesnt look worthwhile for single GPU SB owners.

Keen to get my hands on a 3770K just purely for PCI-E 3.0, when I get the money :<<br />

If we are seeing losses in FPS using PCIe 2.0 now with 2-3x GTX 680s or 2-3x 7970s, just think in a year or two we shall see even more of an impact in FPS! One importance note PoopaScoopa stated was that it's not all about FPS but how smoothly the game runs, as you'll probably notice (sig) I don't upgrade as often as most so getting a MB with PCIe 3.0 (X79 - x16/x16) is a must for me! I don't upgrade every 1-2 years like most, knowing there will be an even bigger limitation down the road is the reason why I'm getting X79. My plan is to run two dual GPU cards so already I'm limited by Z77 running at PCIe 2.0 8x/8x!
