Wanna ask, is it gonna get huge improvement ?
cause i plant to stick with my current rig, and get next gpu, but it seems 7970/new line of gpu come with pcie 3.0 ....

will it bottleneck much with pcie 2.0 if i use next gen gpu ?

sorry if there are similiar kind of thread...

It is a very little improvement over PCIe 2.0. Defiantly not worth swapping CPU and MOBO for. It is a very little performance loss almost not noticeable.

i have been waiting to see this as well how cards like the HD7970 and others once realease will do in a PCIe 2.0 slots if xfired/sli

the new HD7970 shouldnt satuarte PCIe 2.0. though the where do we go next?? could be worth the upgrade in the future but for now PCIe 2.0 is atleast fine for a single cpu

One area, however, where Gen 3.0 could have a performance incentive, could be with future Ivy Bridge LGA1155 platforms, where to run 2-way CrossFire, the single x16 link from the CPU is split into two PCI Express 3.0 x8 links. Those numbers could be interesting.
this is what im wondering about once intels z7x chipset is released or how current z68 gen 3 boards and these results

As we are all aware, even PCIe 2.0 split to x8/x8, the performance hit is negligible to matter at all.

As far as grahichs card goes, the only adavantage of PCIe 3.0 will allow more power draw from the PCIe slot. I burnt many X58 boards' power plane with crazy graphics overclock. But if we are not a benchmarker with multi-gpu setup will have no benefit at all.

But PCIe 3.0 is not all about graphics, other controllers will have huge benefit of the double bandwidth/transfer rate from PCIe 2.0.

Most 1155 boards will support Ivy bridge, and Im almost 100% sure Ivy Bridge supports PCIe Gen 3

like Sandy Bridge-E, Ivy Bridge-E will use LGA2011
