Well the prelim pictures of the NV40 I posted here over a week ago were laughed at, but turned out to be real, and the Aquamark scores I posted are looking like they might be the real deal also. So scoff away if you want, and I promise I won't say I told you so
Some more pics and and a possible price point for the GeForce 6800 and GeForce 6800 over here. Another foreign site I'm afraid, but you get the gist.
Sounds OK to me, if they translate into British prices at the normal exchange rate, you'll be able to get a 6800 for under £200.
