Which is good Dell system for GTX 680? GTX 680 PCIe 3.0

I need to order a new system for GPU development
with GTX 680 (Kepler)
Intel Ivy Bridge processor
and PCIe 3.0
I need fastest data transfer rate in both directions,
host to GPU and from GPU to host.

Can somebody recommend which Dell desktop system
to order?
If not Dell then which manufacturer and which system or which motherboard
best to order?

Is there known list of systems or motherboards which works well with GTX 680?
