No addons, lowest graphical settings, and I get about 17FPS max in most low pop areas. I have tried multiple resolutions (from 800X600 and up) and I didnt' get any noticible difference between any of them (1-3 FPS difference). Granted, when I increase the graphics settings, everything crawls down to mid single digits.

With the ram I typicly see the system usually floating around 600mb loaded in task manager, but againt 300+ is fromt he video card so it's not that bad. I had vista stripped down to the basics and removed the majority of bloatware that came with HP but still no difference

Again, I have not put in the card yet as I haven't had the time to open the case up and take a look yet.
