Hi Jason,
Thanks for your reply. The seller told me that the GPU could not achieve 100% performance (maybe 50%) when the motherboard is a server model one. And he recommend me to change the motherboard to a workstation model one.
But I think the server model motherboard ASUS Z8PE-D12X could 100% support GTX580/GTX680.
So what do you think of that? You agree with me or the seller?
Thanks.
