It mandatary a 3-Way AMD CrossFireX support?
this expensive motherboard:
Gigabyte GA-990FXA-UD5

a sistem with 2 5850 Crossfire is about 550 euro, a 3way almost 800

do not worry about crossfire support

just pointing out the price of those 2 Gigabyte motherboards is pretty close to the MSI GDFXA-GD70 which is a very good board

you just plug your 3 video cards into the PCIEx16 slots... no crossfire cables needed as it works better to not have them set up in crossfire for bitmining..... you may need some dummy plugs or have them all plugged into a monitor though.

I'll comment on the PSU since I own that exact same one. It's a stud, plenty for 3 X 5850's.

I have mine running 2 x 5870's and a 6950.

Thanks for feedback, I have a HX650 whit asus crossair3, amd955 and gtx 570; i need a 5850 also for this pc ^_^

It's all about the game, and how you play it

if the bottom slot does or not is up to your case(the case does have a bottom) get one with 8 expansion slots you'll be fine otherwise go caseless. as far as crossfire is concerned it's determental to mining performance.

Hi mate,

I have the Z68 Extreme4, and the bottom pcie slot won't fit a dual slot card. You'd need to use a riser.

i would go with a more powerful power supply like 1000+ and this mobo http://www.newegg.com/Product/Product.aspx?Item=N82E16813130274

That way you can add up to 5 pcie16 slots with risers for future video cards

also open air instead of a case for mining alone seems to produce the best temps.
