Id love to mate, but im only on air cooling, (prolimatech super mega + dual vipers), been clocking my gpu's this week, hit a modest 800/1600/1700, have to whack the gpu fans up pretty high when running benchmarks, guys on watercooling are hitting 850+ on the gpu cores, (shaders linked) and 2000 memory, coupled with 4.3ghz+ cpu's. To watercool my current setup would cost a small fortune.
