hi

i currently own a creative gforce fx5900 ultra, do you think it is worth me
upgrading to a GeForce 6800 ultra GT, is there a major difference in these
cards that would justify the upgrade. I am looking for better performance
with games like doom 3 and far cry.

my system is asus p4pe, 2.53 pentiun 4, 1.50 gigs of ram

thanks for any help
