Crossfiring an r9 280x and 7970. Do I need to install both softwares?

Hi!

I am just about to crossfire an MSI r9 280x and Gigabyte 7970 OC and was just wondering that do I need to install the CD which came with the MSI AND gigabyte? Or is it sufficient to just download the latest drivers from AMD?

Thanks

Just download the latest drivers from AMD.
Never use the CD that comes with the GPU they come with different kind of Issues and have an Old driver

Just download and install the drivers.

Set crossfire in CCC

What is CCC? Should I use a single or double bridge?

Single bridge. But length depends on what pcie slot you have the second card in. See http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=crossfire+bridge&N=-1&isNodeId=1

BTW. I marked down all of my 3D mark vantage scores and here is what I am getting.

Gigabyte 7970 OC single card : 27 625
MSI r9 280x + Gigabyte 7970 OC : 35 941

Is that around what anyone would expect? It seems like a small jump...

No idea. Google it.

Crossfire works great in some applications and not at all in others.

WOW. I just launched BF4 and used fraps to measure my min max and average and there was quite a significant increase. here take a look at this

- 7970 OC single card becnhmarks BF4 -

* Avg. 40.252 fps

* Min. 0

* Max. 73

- 7970 OC + r9 280x corssfire benchmarks BF4 -

* Avg. 85.455

* Min. 57

* Max. 116

Seems good to me Looks like x4 x4 isn't the end of the world after all

I know!! I'm so happy now especially after the disappointing results from the 3D mark vantage benchmark.

By the way, those benchmarks are on Ultra settings at 1440p BF4.

Cheers!
