Cheap Computer Equipment

I need a motherboard that has the following specs:

Supports ECC RAM
Supports a fast processor socket
Supports Virtual Machines
Has PCI-E 2.0 (at least 2 PCIE slots for two NVIDIA Geforce 295 graphics cards)
Supports RAID at various levels
Has modern bus speeds

I have absolutely NO NEED for SLI. I am not a gamer, but plan to use the graphics cards instead to run time intensive CUDA code. (Hence the need for ECC ram).

It seems like I can always find a motherboard that supports all but ONE of these specs. For example, if it supports PCIE 2.0, it doesn't support ECC ram.

I'm hoping to not have to spend an arm and a leg for an expensive server motherboard, but if that's my only option.... We'll see.

Thanks.
