Hello, I'm back 4 years later after getting my own desktop (whose parts were mainly free) to ask another question. Is there a way to hook up an external GPU to my desktop? The dilemma I face is that since I am using two Radeon 5870's right now in my desktop, I want to create a hybrid PhysX solution, but the last PCI-E slot on my motherboard will only allow a single-slot GPU to fit in my case, it makes my Quadro FX 4600 useless right now. I was just wondering, is there a way to connect the Quadro externally, either by USB 3.0 or some other method? I'm hoping that there will be enough bandwidth so the card doesn't get bottlenecked too much. I still have my PE4H and EC2C from all the way back then.
