Motherboard for 2x Tesla C2070

My lab had an old setup with 2 Tesla C2070 GPUs on an ASUS P6T7 WS Supercomputer motherboard. We also had another GeForce card for display and 24GB of DDR3 RAM.

Recently the P6T7 WS broke down and I need a replacement. It would be nice if the board supports DDR3 RAM so I could just use the old ones. CPU needs an update anyways so CPU socket isn’t really an issue. Any suggestion is appreciated.

Just as a follow up question, if I understand it correctly, each of those Tesla cards uses PCIe 2.0 x16 and the old p6t7 board supported triple x16 no problem. Now that all current boards are with PCIe 3.0, do I need boards that support PCIe 3.0 at x16/x16/x8 at least? or is there any chance I could run PCIe 2.0 x16 card at full capacity on PCIe 3.0 x8?

if you were to get a pci 3.0 and plugged it into a pci 2.0 it will then just register it as a pci 2.0

it would be backwards compatible

So basically I would need a board that supports x16/x16/x8 then? Any suggestions?

no you do not need a new board up to yourself if you want a board that is pci 3.0 x16/x16/x8. the board you have now supports x16/x16/x8 2.0 if your were to buy a pci 3.0 gpu card and plug it into your board it will only read as 2.0 it is backwards compatible for example if usb 3.0 you have and you plug it into a 2.0 port it will read as 2.0 and not as a 3.0 backwards compatible
