Is it worth waiting for Ivy Bridge for PCIe 3.0, even if it won't be useful for a while?

More about : pcie ivy worth

If that is your only reason for waiting, probably not then...There's tons of other reasons on top of that to wait for in my book.

Yes PCIe 3.0 is available, but I'm pretty sure SB doesn't use advantage of it like IB will. So only if you were to get a Radeon HD 7XXX or GTX 6XX GPU, then it would be useful to its full potential.

ivy bridge and pcie 3.0 are two brand new tachs to be introduced this year.
afaik pcie standards change every 4 years, so this year pcie 3.0 starts. it might be around for the next 4 years as more platforms adopt it. games still don't take advantage of the pcie 3.0, but tasks like gpu computing and other bandwidth-hungry tasks already utilize pcie 3.0. amd has already launched 2 pcie 3.0 gfx cards. many more will follow.
among sandy bridge cpus, only sandy bridge-e cpus e.g. core i7 3820, 3930k, 3960x and their chipset - x79 support pcie 3.0. mainstream sandy bridge cpus e.g. core i3/i5/i7 2xxx cpus do not support pcie 3.0.
the motherboard mcnumpty linked only works in pcie 3.0 mode if an ivy bridge cpu is used after a bios upgrade to make the mobo compatible with ivy bridge (in case it didn't come upgraded from the factory).

For the 22nm CPU's 3570k and 3770k yes as they show about an 9% gain clock for clock. They should also up the max OC on air by about 500MHz. For the motherboards the z77 may give an additional boost of 2% with some tests show 15% total for both the board and CPU. The USB 3.0 on the z77 is to be built in so if you know the Etron problems its a good move. I have seen no information on the z77 having 8 dimm slots like the x79's. I say yes they are worth a 2 month wait.
tomsharware has Ivy bridge near 17%.

Cache could help a small bit also.

Research your case, PSU, RAM, SSDs, heatsinkfan, thermal grease, bluray, and OS choices. The other 6 weeks is enough time to pray for HD prices to return to normal. :)
