Overclock snady bridge and forgo pcie 3.0? Longevity?

[gr8mohawk]

I've heard the ivy bridge doesn't overclock much at all because heat issues. So I was thinking of just getting a sandy bridge. But then no pcie 3.0

So what would give a new build more longevity, more CPU power or PCIe 3.0?

I've read that newer GPUs don't really need PCIe 3, they work almost as well on 2.0, do you think this will remain the situation for the next 2/3 years, or do you think newer GPUs will really need 3.0.

you should be able to get 4.5ghz out of your ivy bridge chip, which is about the same as a sandy bridge 4.8ghz.

pci-e 3 isnt useful right now. you can go without it
