Yeah, I've never really seen those coolers before but there again I haven't been to much watching the CPU market these days >.> Feels like I spent tons of money/time on mine and got it to 4.2GHz with a kickass full load temp on my CPU and do nothing special with it these days. The likes of Prolimatech and Thermalright make some really nice coolers. Here's what I am using.

Yah, It's a beast
Dropping back to XI running a single GTX 275 (when I have two) and a 4.2GHz overclock seems sooooo much overkill for the game (Yes, we both know it is >.>).
Enjoy your rig!
