Yeah water cooling allows you to do some heavy overclocks. BTW my score was done when I had a single HD5850.
I see that is good indeed. What's your temp on full load?
I finally got i7 930 up to 4.0Ghz
Tweaks a few more setting on GTX 480 stock fan and it went pretty well.
Upped core clock to 840 | 1680/2050 | 100% Fan | Temps 74C (sounded like JET engines haha... /Water Cooling Yes Please!)
About 500+ for both High and Low compared to what I got before.
High: 4,244 @1920x1080 | Load Time:10781
Low: 6,250 @1280x720 | Load Time:10808
High: 4,707 @1920x1080 | Load Time:10446
Low: 6,822 @1280x720 | Load Time:10979
