I was just wondering if my motherboard supported crossfire (2 graphics cards) because I am planning to buy another Asus r9 290x to go with my build. All replies are very much appreciated.
Also, how much does crossfire GPU's actually improve you performance while gaming and doing the normal tasks a computer does?

My motherboard is the Asrock Z87 Extreme4.

3 x PCI Express 3.0 x16 slots
-single at x16 (PCIE2)
-dual at x8 (PCIE2) / x8 (PCIE4)
-triple at x8 (PCIE2) / x4 ) (PCIE4) / x4 (PCIE5

The 290x goes up about 33% compared to say 47% for SLI

Both are 'averages" thrown off by games that do well enough on one card that the 2nd cards additional performance is both relatively small and unnecessary.

As you can see here and on the following pages, scaling is...

As you can see here and on the following pages, scaling is usually very good in demnanding games.

Few applications are designed to utilize SLI/CF

Click to expand...

Single = One GFX Card (which will work at x16)
Dual (aka SLI / CF x 2) = Two GFX Cards (which will work at x8)
Triple (aka SLI / CF x 3) = Three GFX Cards (with will work at x8 x4 x4)

nVidia doesn't allow SLI at x4, AMD does
