i have a gtx 650 and a 9800 gx2 can i run both as dual or would it not even make a difference as far as fps and if not which one should i use for games like titanfall and bf4
Dear SLI can be created on same model only. So it would not do any good if you connect both without SLI. So, pl use GTX 650 as it has better support for games as compared to the 9800 in terms of speed, support for new versions of DirectX etc.
