Asrock Z77 Extreme 6 & 2 Way SLI Support

they should be far enough unless you had like a triple slot cooler on your cards.

My 2 GTX 560 Ti's look like this;

Would there be any noticeable difference between PCIe 2.0 & 3.0? I'd upgrade my graphics cards if it were possible, but money is an issue & I'm pretty happy with the 2 GTX 560 Ti's in SLI

A GTX 670 or 660 TI would be great, but I'm already at my upgrade limit of about $700

I checked out the Asus P8Z77-V Pro & it looks like a nice board & is only a little more then the Asrock Z77 Extreme 6 (I'll have to think more on that)

the difference between pci-e 2.0 and 3.0 is like 1-2 fps, and thats only applies to pci-3.0 cards. GPU's this age havent fully utilized the full speed of a pci-e 2.0 lane. heck technically a gtx 680 in a 4x slot still runs at like 94% speed according to a slightly old test i cant remember which page it was on. Its going to be awhile till gpus fully utilize a pci-e 2.0 slot+

Here's a great PCIe 3.0 Scaling bandwidth article - http://www.techpowerup.com/reviews/Intel/Ivy_Bridge_PCI...

Short answer the PCIe 'Interface' is negligible until you look at 3/4-WAY SLI with very High Resolutions and Settings. 1 GTX 670/680 = 2 GTX 560 Ti's.

SLI GTX 560Ti is perfectly fine for HD (1920x1080) and there's only a few games where you'll have issues with very high settings and AA.

Thanks for the article   It was nice to read & check out some of the results (there's not much difference between 2.0 & 3.0 with only a few FPS difference)

Thanks for your replies guys   I'll have to decide on either the Asrock Z77 Extreme6 or the Asus P8Z77-V Pro. Both boards seem like a great addition to my upcoming upgrade paired with an I5 3570K.
