Well since its an onboard video card you would want to disable the onboard one you do this by reseting the computer and entering the bios setup its either f2 or f11 on HP's I forget. But if your going to go SLI with two monitors I would get two good pci express 16x video cards and not use the onboard which wouldn't work since its not SLI certified. And FPS always has to do mainly with your video ram when runing a game. Unless minecraft takes 4gbs of ram because of a major memory leak there is no way you will ever need much more then that. I'm running 32bit vista ultimate takes around 1.3gbs to run all of my program processes that leaves almost 3 gbs for gaming a window for starwars the old republic is about 1.6gbs cause it memory leaks like a hoe but i still manage to keep msn up 24/7 and open other pages and listen to music. If you told me you only had like 2gbs or 1gb i would say sure ram would do it but knowing your onboard card sucks because i have the same card i can bet that if you upgrade your video and your gaming is gonna see major improvements. If your ram was low you would be seeing stuff like opening IE and get like memory errors or like using your normal programs outside of games you would notice lag or not loading or memory errors but if all of that is fine then its video only. There is sites that let you check to see if you can run certain games with the video card you have just search google and try one to see what it says but I know that video card can barely run world of warcraft which is a pretty old game and thats with lowest settings.
