The GTX 550Ti has been fine in the games I've played, though the newest I've played but it's a couple of years old and will likely really start showing it's age soon. Medium settings are fine for me. I'm not looking for graphics any greater than current consoles and fluidity of gameplay is much more important to me than high res. Will I get a lot of benefit by adding a card? IS there a better single card to upgrade to around the price of an additional 550 Ti that will offer better performance than the SLI setup? (650 Ti?) Are should I just wait to upgrade to a better single card. I'm not going to upgrade to a more expensive better card now because I'm deploying in February so an even better card, or current cards at a a cheaper price, will be available by the time I return about this time next year.
