Promiteia or Mach II? Worth my extra $400?

Recently Ive just come into the market for a phase change cooler. Ive always been fond of the Prommy but when I went to browse the chip con site today, Low and Behold! Theres a new Prommy out. MachII.

So I looked up the prices, $1000. Ouch. Worse than the old prommy.

Ive been talkin with some folks over at Bowmans site www.phase-change.com and Id like to get some input from a larger audience.

So any of you guys with prommies, you think its worth an extra $400-500 for an extra 10-15 deg C lower temps, improved computer and software upgrades?

Will it be that much of a difference in your opinion between overclocks from a Prommy-I and a MachII?

Couldnt I gain some ground between a Prommy-I and a MachII just by charging the Prommy-I with R404?

Thanks forum!

Disregard this thread I posted it in the main General Cooling section also.
