Hey, I have a Gigabyte 78LMT USB3 Motherboard, and I've been told by a TigerDirect online service rep that it won't be able to use an EVGA GeForce GTX 750 Ti GPU. Is this true? If so, what are some GPUs of the same or lower price that offer performance to rival an ASUS Radeon HD7770, which I'm returning due to general driver and card issues/framerate lockage.
 


Thanks. He actually admitted to being wrong after I questioned him. I have a 550w PSU, so I'm good on that front. I notice you said it has PCIe 2. The GPU has PCIe 3, will that cause problems?
