KillyKillall,
About a month ago I upgraded my man computer from a P4 3.4C (800 MHz FSB w/HT) to an FX-53 939. I now have the MSI K8N Neo2 Platinum. Until Monday I was running the ATI Radeon 9800 Pro 256MB from my "old" system. Now I have an HIS Excalibur X800 XT Platinum (256MB) which smokes! It literally gives me twice the framerate in the Halo timedemo as my 9800 Pro 256MB did. It was very expensive though ($550.00 + tax and shipping)!
A few numbers (everything set to "High" and/or turned-on:
1280x1024 = 84.115 FPS
1024x768 = 103.575 FPS
800x600 = 112.286
I play at "Legendary", and even at 1280x1024 the gameplay is REALLY fast and smooth. The badguys move a lot faster now! The game looks absolutely fantastic with everything turned on and maxed-out.
It all comes down to three things:
(1) How bad do you want the performance? Do you "have to have it" now?
(2) How much are you willing to pay for it? Six months from now the prices may come down substantially
(3) Does upgrading the video card make since without upgrading the motherboard and CPU? To run an X800 XT ot 6800-Series card you need a pretty fast system to get the most out of the card. You don't want to drop BIG bucks on a new card only to have your CPU and/or other components be a bottleneck.
From the tests that I've seen, the 6800 Ultra (which is the competition for the X800 XT) runs the majority of games slightly faster than the X800 XT WHEN ANTI-ALIASING AND ANISOTROPIC FILTERING ARE TURNED OFF OR NOT USED. When turned-on and run at high resolution the story changes.
Both the 6800-Series and the X800-Series are both good cards. I bought the HIS Excalibur X800 XT Platinum because it features the Artic Cooling IceQ II cooling solution. If you haven't seen it its' really cool. The heat from the VPU is vented to the outside of the computer case so you don't get the heat build-up you normally would without the venting.
Here's a link to the HIS website:

And one to reviews of the HIS Excalibur X800 Pro and HIS Excalibur X800 XT Platinum on Tom's Hardware Guide:

If you want to see the performance difference, try running one of the the timedemos to see what you numbers are. Of course, your system is probably very different from mine or Tom's testbed system, but you can get an idea of what you could be playing.
