I didnt read the article but I'm assuming a driver will fix this. (based on other members posts in this thread) And ivy isn't even out yet so we can't get pci-e 3 until then ANYWAY...?

LGA1155 SB doesn't even have pci-e 3.0 so... The boards might have but the CPUs don't support it.

PCI-E 3.0 works, it is just not ratafied yet, so nobody can officially claim it, though Intel themselves has no problem claiming so.

(PCIe 3.0 just need a cert driver.)

post #33 of 100
obviously this hardware still works with 2.0 and well at that, Good neough for me, I wont be buying any time soon, but Im hoping for a godly revision to be released, I only ever buy nifty revisions lol

Like the 8800GTS 640MB, (not as good as the ones released right after it, but the higher Memory Bit interface and Memory allowed my MMO's to run better with my resolution)
and my GTX 275, its just the proper kind of card for me =)

I would have grabbed a GTX 560ti 448, but Its too early, i think i have another year left in this GTX 275 before Im done with it =)

There aren't any problems, my 7970's work great on x79.

The EVGA website lists the GTX 680 as running PCIE 3.0. Did I miss something?

What do I care? I paid proper money for X79 board and that card!
Even if it would decrease performance I would want PCI-E 3.0. mad.gif
When I had AMD/ATI card everyone complained about their drives (even I did sometimes tongue.gif ) but they dont/didn`t take 3.0 from us!

Also if you're going to go Ivy Bridge and spend that kind of money on a new CPU, you might as well get the new chipset to match it to get the full benefits. There's a lot more to Ivy Bridge than just PCIE 3.0.

The 'articles' you describe benchmarking the difference in PCI scaling have since become obsolete with the release of the 7970 and gtx 680. They are pushing the same rendering performance as the older DUAL GPU cards were back when those articles were published. To date, there hasn't been more than 1 or 2 articles published on PCI-E scaling with the 7970 and especially not one with the GTX 680. With the 7970, 8x PCI-E 2.0 actually diminished performance up to 30% in some games that depended upon the bandwidth, such as titles that are memory intensive.
