So we're fanboys because we're enjoying the game huh?
Why do you even post here Sotonin? Just to spend time insulting people for *gasp* enjoying a game that you don't enjoy? Please just go away.
As far as the original poster, 1 gig of RAM will help, but as Druss said, you will really want to consider a better graphics card also. You can get something decent for $100 if you look around, but if you can spend at least $150 you can definitely move up a few notches.
I ran extremely decent with a Radeon 9600, and I think it cost me maybe $125? And that was a few months ago. Its not high end and its not going to run well at high graphics, but with high performance turned on, it was very doable, and the lag was not significant. I used to be virtually unable to run through SQ or NQ because I would constantly freeze up, its a ton better now, because I cleaned up my settings (balancing more towards the performance side instead of the graphics side), and also SOE patched some stuff that seemed to have reduced the lag.
