Nice review there, I really thought I would have to be canceling my 8800gt order! But not quite. I've never had an Ati card, but I take it the price will be around £130 and up for pre oc'ed cards. Is the powercolor a reasonably middle of the road brand for Ati?
The cooler looks pretty decent, found a link to manufactures of them:
For a stock clocked 8800gt you can get it for 250 at zipzoomfly.com right now its out of stock but if anything its less. I do love the fact that ati is cutting down on power consumtion and higher temps.
