as u can see from the pic here i had a 6150se integrated. and bought a 8400 GS. I disabled the old graphics card, plugged in the new one, then proceeded to download the latest drivers for windows 7 64 bit off the website. But i dont really notice any performance boost when i go to play games. still same settings as before and still lag like before. im convinced that i didnt install something right. or is it something else.
