What's disappointing, the lack of PCI-E 3 chipsets or the performance gain between 2 and 3? Nobody should have had any hope that 3.0 would bring any real performance gains.

I love how another article completely misses the mark. Of course a single card running a single monitor isn't going to max out PCI-E 2.0 and fully utilize 3.0. It will be useful in multi-GPU setups with multi-screens where GPU use is heavy frame swapping in crossfire/SLI and PCI-E lanes are limited. An example would be IB using two 7990's in 8x slots running eyefinity. I guarantee you will see a nice performance boost with 3.0 over 2.0 in that scenario.

shows that x8 is enough for most people. which is why Z68/P67 is the ideal gaming platform.

Just to clarify for those of you who are thinking this is a bad result: The "bottleneck" here are the current fastest GPUs. The PCIe link is actually capable of supporting way more bandwidth.

for now. but not if you're building a new rig today to use for many years into the future.

people ran tests to compare pcie 1 to 2 when the first pcie 2 cards came to market. there was less than 3% difference back then. but 1-2 generations of cards later and the difference widens.

^^ But those of us with PCI-E 3.0 compatible boards that are z68, are fine for the future.

If it were worth it, I would go buy an IVybridge CPU and a let's say 8970 3gb GPU next year or the year after.

This doesn't look good for LGA1155 HD7970 crossfiring, since PCI-e 2.0 x8 ~ PCI-e 3.0 x4

Just so people know, it's not the PCI-E protocol that will make a card faster, it's the architecture...

just saying.

I wouldn't go that far and say it doesn't look good, you'll still get a big performance boost either way.
