AsRock 970 Extreme3 R2.0 wanting to Crossfire 7850

bassybekx · Oct 1, 2013

So I have an AsRock 970 Extreme3 R2.0 mobo with a Sapphire HD 7850 OCd to 920mhz clock and 1250mhz memory (help on overclocking graphics wanted aswell)

My main question is how well will crossfire perform on this board with two 7850s .. I onow that there is 2x PCIe 2.0 - 1 @ x16 - 1 @ x4 .. currently getting 55-63 fps in bf3 and 35 - 60fps in bf4 beta .. thinking crosdfire will help or is there a better option to get better fps .. ie upgrade ram or overclock ..

Full Spec:

AMD FX 8320
Sapphire HD 7850
240GB SSD
2TB WD HDD
Corsair GS 700w
ASRock 970 Extreme3 R2.0
Corsair Vengence 8Gb RAM
Corsair H80i Cooling

Thanks for any and all help guys .. first time here so I really hope I can get some help

7850 Crossfire in Battlefield 3 Ultra 1080P is Avg. 98FPS

ok excellent .. but my mobo has 1 x16 PCIe Slot and the other PCIe is an x4 when the x16 is in use .. will that have any performance issues?

patrick47018 · Oct 1, 2013

Yes that will cause some performance issues

im sorry but your being very vague .. such as? in what way? and is it worth crossfiring ??

patrick47018 · Oct 1, 2013

I am sorry I am currently in class. But the x4 will definitely be a bottleneck, it wouldn't be worth it, you would be better off selling your current 7850 and buying a single more powerful card. October 15th AMD is releasing their new cards and some of them are supposed to be quite low cost, I would not recommend doing a x16 + x4 crossfire, not worth it. If you have any other questions I will gladly help
