Definatly the most likely release date right now, since any later would null any advantage over ATI's supply issues.
Power requirement is also rumored to be around GT200 levels. I'd exect the high end part to be around £350.
What? Firstly you do of course realise ATi/Nvidia make their cards IN THE SAME PLANT, with the same incredily low yield process, with Nvidia with a bigger core they can't possibly get more cores per waifer, but likely close to 30-40% less cores per waifer.
Whatever supply/manufacturing issues ATi have, Nvidia have, but also with a larger core that gives less per waifer to start with. Null any advantage? ATi are selling right now.
Power requirements at GT200 levels? no, high end at £350? very very very unlikely. Released in 2009, with anything more than a half dozen available worldwide, no. Nvidia had to fake the part they "showed" while claiming it was real, they lied about it working, yields, the fact its working and the fact they were getting A1 silicon only what a month ago. Its just not going to happen.
The only way Nvidia will sell cheap is if they make no profit, which I'm happy with, it will still push prices down on ATi cards, which is good for us, but I can't see a card listed as pre-order for 2 months will cause price drops.
Hope I'm wrong, but considering Nvidia lied so publically about having working cards just to fake launch their products just to delay people buying ATi doesn't inspire confidence
I want 2x5850's, at £150 though, sooner Nvidia come out the better, sooner TSMC up yields, the better for all of us, end users, ATi, Nvidia.
