PCIe 3.0

I was just going to ask a similar question.
I'm currently running a Gigabyte X58A-UD7 with a 8800GTS-512, I'm going to be updating the vid card shortly but how far away is PCIe 3.0?, if Mobo's and Vid cards are going to be moving to PCIe 3.0 pretty soon I will hold off on the Vid Card purchase.
Regards

The first PCIE 3.0 boards are expected in Q3 when Intel release their "enthusiast" level Sandy Bridge CPUs and motherboards.
If your graphics card need an update then I would not hold off on account of PCIE 3.0 - a x16 PCIE 2.0 slot provides more than enough bandwidth for modern top-end graphics cards. Also, PCIE 3.0 tech will be comaptible with PCIE 2.0 tech.

What is the maximum bandwidth of x 16 PCIE 2.0? My 5850 has a bandwidth of 128.0 GB/s. Or in other words what bandwidth/speed is required by the graphics card before it gets bottlenecked by the x16 PCIE 2.0?
8 GB/s on PCI-E 2.0 16x. Bandwidth isn't as needed now as it once was though because the GPUs are so much more powerful and have much more on-board VRAM so they do not need to access the CPU or RAM as much as they used to. Using an 8x slot instead of a 16x usually results in a ~2% performance drop, which shows you how little an upgrade to PCI-E 3.0 is needed today.
I always wondered how big a drop in performance you'd see from that. Guess it's mostly a case of motherboard manufacturers wanting to sell new, more expensive tech to the customer than us actually really needing those new fast lanes as soon as possible!
