Hi I've played the game some days now but I think my computer is a bit too slow. The FPS i horriblr some times. When I enter open areas and areas with alot of ppl the pace goes very slow. Now I have an Intel Core 2 Duo 3,0 GHz, 3GB RAM, and an ATI Readeon 4800 series. What would be my main upgrades to get it running smooth? RAM CPU or GPHX? Please advice...
