I want to get three monitors for a racing sim. At the moment i have a gtx 960 2gb vram. Im sure 2 gb vram wont be good enough. So the question is, should I buy a gtx 1050ti (4 gb VRAM), slot it into the first pcie slot and use its vram. to then put my gtx 960 into the second pcie slot and put them in SLI. Should I do this?
