I just updated my video card from a NVIDIA 8600gt to a NVIDIA GeForce 9400 GT 1GB DDR2 PCI Express Graphics and upgraded my ram to 4 gigs. After installing I have not noticed a great jump in my FPS. In fact it stayed about the same. I have turned off the vertical sync in game and the card has it turned off as installed. The question I have,was this a good enough upgrade over my old card to expect an improvement or could it be my overall system? Please be kind as I am a noob when it comes to computers and the interworkings thereof.
