Some are: ASRock 990FX Extreme 3, ASRock 990FX Extreme 4, Gigabyte 990FX UD3, Gigabyte 990FX UD5, ASRock 990FX Fatality, ASRock 990FX Extreme 9, ASUS Sabertooth 990FX, ASUS Crosshair Formula-V or Z, ASUS M5A99FX PRO, MSI 990FXA-GD80V2, BIOSTAR TA990FXE, and the Gigabyte 990FX UD7.

I'd recommend the Gigagbyte UD3 or UD5 though.

While I'm all about systems performing at peak potential, I gotta wonder if buying a new motherboard is the best move. I would think invest in a single 7850 and sell the 5770's. I'm betting the overall cost would end up being about the same, and you would never have situations when crossfire performance is less than optimal.

If I upgrade to an AM3+ I can also upgrade to a better CPU at a later time. Perhaps one of those fancy new 8 cores once I have the cash. I prefer to keep my current GPUs because my wife gets my hand me down components and the HTPC gets hers. So once I finally do upgrade my GPUs she will be getting my crossfire setup etc.

I would certainly go for the motherboard given your situation, I have an ASUS Crosshair V Formula-Z, With Dual crossfire it will run both the PCI-e lanes at 16x. If you put 3X crossfire it will run them at 16x/8x/8x. (from the manual) I don't think it can support quad SLI/crossfire though

It uses the 990FX chipset and supports 32GB ram. It also comes stacked with tonnes of bonus features like inbuilt Supreme FX III sound chip, OC'ing features etc.

I'm starting to sound like a salesman tongue.gif

I think the red and black theme looks great too thumb.gif

Basically any X8/X8 or x16/x16 will do perfectly. HD5770 will not bottleneck a x8.

I would avoid MSI AMD boards. Biostar is a good 4+1. But I would stay with a traditional 8+2 or digital 6+2 VRM setup.
