Hi i'm planning to upgrade my dell optiplex 780 sff to the max but when i search for the best gpu everyone says the gtx 750 ti low profile is the best but the problem is that i would have to move the hard drive and things around to fit it in, so i was wondering whats the best gpu for the dell optiplex 780 sff that doesn't require me to move other parts around in the PC to fit it in
