Can the 870A-UD3 do Crossfire/SLI? - Page 2

post #11 of 15
Depends on your price range.

Might want to wait a bit, Bulldozer should be comming out in a few months, and all of the major manufacturers will probably refresh their lineups

I wouldn't recommend that as the 5xxx cards have scaling issues so it would be pretty hard to judge if the 4x is bottlenecking. Just run your existing single 5870 on the 4x instead of 16x and see how much perf you lose

I have the board in crossfire mode and it works just fine. Have no problems with bottle necking. It works just make sure you have more cpu memory than both boards combined and u will have no bottle necking.

Tell me, what do you plan on running. What do you want your motherboard do? Just Crossfire? Plans for SLI if you change your mind? Or would you like both options? Do you Overclock your GPU and CPUs?? How many SATA ports do you like?

Familar with BIOS or UEFI?

With your 1055T, I see that a basic board like Gigabyte 990XA-UD3 would do. If you want a simple build with the option to Crossfire/SLI down the road.

But if you're tinker, wants to go extreme and plan for mutliple cards setup, then I recommend a step up in the 990FX series.

ASUS Crosshair V Formula
ASUS Sabertooth 990FX
Gigabyte 990FX-UD5
ASRock Fata1ty 990FX
Asrock 990FX Extreme3 (if you hate the Gaming Fata1ty).

Good luck!
