ATI Radeon X1600 / 256MBs, and RAM

Does this video card run better with more RAM? Cause I need to know if I should get 1 gig, 1.5 gigs, or 2gigs. I'm mostly going to be playing games like, Halo, WoW, Battlefield 2, Need for speed, quake 4, Unreal Tournement 2004, Call of Duty 2, and others games like those.

Thanks.

I have this card, i recently upgraded from 1g to 2g, i dont know about every game but gained

6fps on average score in f.e.a.r,

I gained like 20fps on max score,

and 3fps on minimum,

(in performance test) 

I mean is it worth the extra cash? I want to spend as little money as possible without losing any performance.

I spent $50 on a second 1g mem stick (2gb total), the whole computer seems more responsive and runs smoother, it's not a huge difference but i think it's worth the $50

I never tried 1.5gb so i cant say

If you have a intel core 2 duo processor upgrading to a better video card would be worth it.

Anything else (even x2 athlon) you will be dissapointed in the amount you spent for the performance gain.

(is $300 really worth 10fps in a video game)
