Get the latest drivers from Nvidia if you don't already have them (ver. 61.77)
Not true! Most of the newer drivers will decrease performance with the 5200. I have basically the same set up and find the 61.11 to be the best drivers yet.
I have tried just about every driver there is for the Nvidia cards and anything above 61.11 either decreases performance or becomes unstable . The newer drivers have all been made to run games like Far Cry which most know won't run good on a 5200, so it is really pointless trying to update to a newer driver for a video card that you know still won't run a game smooth, sort of like putting racing fuel in a lawnmower.
Of course though no two computers are alike and you may find that different drivers might work for you than for me. Only way to tell is to give them a try. But may I recommend before doing the "driver challenge" to download Driver Cleaner 3, and use it everytime you install , be sure to follow instructions and no conflicts should arise, this is the important part you must remove the old driver completely before install of a new one!!! Otherwise you'll end up with problems that will affect more than frame rates
