Alt didn't say anything about a 6800Ultra just 2x6800... I dunno Alt were you talking about Ultras?
Either way, The new 7950 will blow a 6800Ultra AWAY! And we're not talking about an advanced setup here with phase changers and the likes. Just a standard setup. Its just the price for the 6800s which ever he wants.
Side note: If you already have the 6800s then rock out.
Its just buying 2 gpus, a sli ready mobo ( if not owned ) and a good sli psu would be a lot more than buying lets say a 7950 or a X1900XTX.
For that price though you could get a 8800GT which will be available soon and cost from 450-500 and be DX10 ready core 1.5ghz and enable HDR+AA. Something Nvidia has been behind ATI in.
Also COM check out the new 8800s. The GTX which will be above 600$ comes with LIQUID cooling on the HSF.
