Thanks for the reaffirmation Jaydee. I suppose that to my untrained eye this block has the potential for "best in class" performance. Allthough I'm not sure what that means since my impression is that with GPU blocks the goal has resided in minimal restriction. My unsderstanding is that restriction is always an issue to take into account when introducing multiple blocks in a small loop.

A while back I bought one of the asetek GPU blocks with no pins or channels (aside from manufacturing defects). I purchased it because of the price and because of the unscientific assumption that it would be the least restrictive solution. Aside from the fact that I fully expect it to eventually crack, I'm more than satisfied with its' performance and minimal impact on cpu temps.

The fact that the product page recomends 1/2" or 7/16 tubing seems odd to me and I've never seen a GPU block advertised this way. This lends me to beleive there's potential for restriction issues. While I like the look of this part, I would likely install it in a 3/8" loop.

I'm in the midst of rebuilding my loop and there's a good deal of equally priced GPU solutions out there. At the same time there's little data available. Ultimately my question boils down to how would the MP-1 affect performance compared to the MAZE4, Swiftech, etc. I suspect the answer is 'no significant difference' within a limited testing environment.

My planned setup: 3/8" loop with a MCW6000, DDC, MCRES1000, and a PA160 cooling an OC'ed Venice A64 and 7800GT. I would welcome anyone's comments if they think one GPU block would be better than another with this system.
