WOW, sli 7800gtx for UT2k3. The most graphically demanding game today....
Man, that game must push those two cards to the
ABSOLUTE LIMITS
Guandi,
He already pushed overclocks to 490 core and 1.3 ghz mem. That would get 7-8 fps improvements. I doubt you will get more than 2-3 fps improvements on further overclocks. So is it worth your money to watercool when you have artic silencers on already, no unless you want complete silence and some extra juice. IMO, the artic silencers are very quiet already. Removing the thermal pad will just keep temps a couple of degrees lower and is easy to do.
As for Guandi.
a single 7800gtx will handle that old game, UT2K3, with all the bells and whistles enable to the max on a 19 inch and still get 130+ FPS. Why you have them in sli is beyond me when you get nothing out of that second card and the $400-$500 you threw away. Buy some new games man
Sheer FPS.... All you need is 80 fps. That is good enough because it is an average rate so FPS can be drop. At 80 fps, it will hardly ever drop below 60 fps, the rate when your eyes start to notice differences in framerates.

These are more gpu demanding games and still get 80 fps with AA and high quality settings, very large high resolutions that i doubt you can use on 19 inch, and with a single card, not sli.
