New graphics card..worth it ?

Hi All,
I want to upgrade/replace my whole system at some point
but what with Vista,DX10 etc etc i cannot see the point
at this present time.
So what i was considering was upgrading my Graphics card for now.
I have an ATI Radeon X850XT platinum at the minute.
I was thinking of getting an ATI X1900XTX.
The PC im upgrading is mainly used for gaming the likes of
Ghost Recon Advanced Warfigter,Fear,Call of Duty2 etc.
What id like to know is if its worth upgrading to this card?
Will it really make that much of a difference with the games that
im currently playing ?
My system is A Dell XPS Gen4 with intel P4 640 with 4 gb of ram.
Thanks in advance for any input

 

I wouldn't bother, maybe if you're rich get a 7600GT or something, just to make yourself happy for the time being. That's what I did, and I'm not rich.

 

yep not worth it at the mo. vista is only a couple of months away now....

 

definitely hold off.

a 7600gt would be a completely sideways jump from an x850 and a total waste of money

your current card should handle all those games fine anyways

 

Thanx for the responses guys
i will wait till see what happens with all the new bits and pieces coming
out etc etc.
