thanks guys. i guess my last questions are - will there be a significant increase in my FPS and textural qualities? and will the temperature and noise level of my rig be effected?
The noise should be roughly the same, I can hardly see that card make more noise than 2 7850s. It should run cooler, since it doesn't have 2 GPUs anymore. As for the increase... It will mostly depend on the game, but you will surely be seeing an improvement and a reduction of artifacts, if you every had any.
