PCI-E 3.0 boards for AMD?

[blim]

Hi,

I have read about the ASUS 990FX Sabertooth Gen3 R2.0 having PCI-E v3.0 but the one on OC is v2.0!?!

http://www.overclockers.co.uk/showproduct.php?prodid=MB-576-AS&groupid=701&catid=1903&subcat=2046

Is this not Gen3 or something or just a misprint?


This isn't a budget board but if any other boards support this, could anyone recommend one that isn't too pricy.

Thanks

As far as i know, FM2 is the only PCI-E 3 platform.
AM3 is a dead platform, it's finished.

I'm not sure on what to do atm. I wont to upgrade but AM3 is old and I'm running a bulldozer which doesn't help.

I basically wont in on AMD mantle and would need to upgrade my card (6970 atm) but my motherboard might be a problem. Crosshair IV formula 890FX, not sure if it will support a R9 280x.

Plus it would be nice to move up to 990FX chip but is it worth it, can I still run the R9 280x with my setup?

Any ideas?

PCI 2.0 is fine, won't any difference at 3.0, not yet anyway. You will see a difference from bulldozer to steamroller, not sure how much though.

A 8350 OC'D is half decent with good cooling, and the 280X is a good upgrade.

Not 8350, get the 8320. Really not worth the extra £30 for like a couple of hundred Mhz of extra clock speed which you can overclock anyway

If memory serves, the ASUS 990FX Sabertooth Gen3 R2.0 uses a bridge chip to provide PCIe 3.0 by using two PCIe 2.0 links to the CPU.

You can't get native pci e 3 on am3+.
Not that it matters, the 280x will work with your set up as is. Your bottleneck will be your CPU.

Yeah, no need for PCIe 3.0 for a 280x (or any single GPU card, I would think)

Anandtech investigated PCIe bottleneck a couple of years ago using a 7970 (which the 280x is a rebadge of);

No difference found between PCIe 3.0 and 2.0 (PCIe 3.0 at x8 is the same as PCIe 2.0 at x16)
And only a small difference dropping down to PCIe 1.0 speeds.

Yeah, I remember reading that when it came out. I wonder if it's still the case with 290x/780Ti's .etc...
