Well, are you not satisfied with the performance of any game you are now playing? If you are not, check benchmarks and see if either option will give you the FPS and/or eye candy you want. If neither will, don't bother. Otherwise, which option will you regret in 6 months? You can get a second 295 for SLI in a few months, but if you do SLI now, you'd be throwing even more away if you need a further upgrade.
