Second graphics card in X4 slot?

Hey Guys,

I have to buy a second graphics card beside my GTX 570 for CUDA. My motherboard only has one PCI-E X16 slot, so i’m looking for a card to run in an X4 slot. Of course, only NVIDIA. What would you suggest? The GT 430 looks good, but i don’t know if the X4 is enough for that card. I have an FSP Aurum 600W PSU. Thanks.

x4 aint for gpus you need a motherboard that supports SLI…

PCI-E x4 is perfect for a GPU such as GT 430, but you will have hard-time to find a PCI-Express 4x version of this card :(
