Anyone tested the same GFX card on PCI-e 2.0 and 3.0

Is there any noticeable gains?

Is there any noticeable gains?

Kaap has (I'm sure he will post his results) and now i could, however no there is not very big gains. At 4k or triple screen resolutions might you start to see more than a couple of percent difference, but anything below that the difference is small.

Not anything I noticed from using my x58 setup or the haswell system in sig. Maybe a bit with multi gpu. Which I haven't ran in the old system.

Thought as much...Just ordered a Samsung Evo for steam and OS do you think I need a sata 3 card for my x58?

With a single GPU card, you'll notice a difference between gen2 and 3 in a slot with only 8 lanes, but not with 16. A dual GPU card like the Titan Z or 295X2 would probably show a measurable difference in a 16x slot.

Ivy Bridge PCI-Express Scaling with HD 7970 and GTX 680

Only 1% between 2 x16 and 3 x16.

The new PCI-Express 3.0 interface can provide around 1% performance boost for both HD 7970 and GTX 680. While this confirms that both cards provide working support for Gen 3, such a small improvement is clearly not worth worrying about. It certainly does not warrant buying a new processor or motherboard. PCI-Express is forward and backward compatible, so any PCI-Express graphics card will work in any motherboard's PCI-Express slot, no matter which version each component supports.
