why ? why doesnt you put it on a new system?
i use a 1024*768 resolution monitor does that improve its performance?
It will play the games you want. The BF3, Skyrim type games will be med to high, all other games will be fine. In my opinion when you build a new rig it would be better to put in a better gaming card.
Like the GTX 560 Ti or better as compaired to the GTS 450. This what I ment by that. I do wish you good luck on your new card and your new rig when you get around to it.
