Aparajith said:Does it support Crossfire as well as SLI? Cos from the website I see that only Crossfire is supported.
This's the board:
GIGABYTE - Product - Motherboard - Overview - GA-EX58-UD3R-SLI (rev. 1.0)
AFAIK the integration of both SLI & CF on X58 chipset boards came later on and seems like Gigabyte has released the newere revision of the UD3R board under the name UD3R-SLI.

U can as well go for the MSI Eclipse. SiriusB, a TE member owns the board for over a couple of weeks and seems like he's doing some good stable OCs on it.
