So I've got somewhat of a frankenstein of a system going. My mobo/graphics card are new(relative to my old parts), P4C800-E deluxe and GeForce 6800 respectively, but my CPU and RAM are older, a P4 2.8 (400 fsb I THINK, COULD be 533, but I doubt it) and 1gb of DDR333. Now, would upgrading my CPU and/or RAM really give my computer any noticible performance difference? I do game, finished Doom 3 and it's expansion, FarCry, and now working on Quake 4. I'm basically wondering if getting a new CPU and some new RAM would allow my 6800 to open up a bit. Any advice would be appreciated. Thanks guys.
