My motherboard has 2 x PCI Express for the GPUs so yes, it is ok. My case is a Midi Coolermaster GLite, but it can fit a reasonable large GPU. The PSU is a 450W Coolermaster.
I found that VGA ASUS GEFORCE GT710 GT710-SL-2GD5-BRK 2GB GDDR5 PCI-E can support 3 monitors at once.
My monitors have only D-Sub inputs, so I guess with the right convertors (DVI to VGA and HDMI to VGA) the job can be done. Right?
My question is, can I use two GT710 gpu cards at once?
