Only a few days until we do find out!
It's not launching at CES, almost impossible, shown, sure, launched with specific specs we can believe seen on slides that are official, almost 0% chance of that. Might we here the 380GTX is a 512sp part at 2Ghz, sure, might that become a 380gtx ultra mega can't buy me EVGA part by release, sure.
Its trolling without question but the load temps aren't anything out of the ordinary, its a power monster sure, but temps are based on concentration of that power on the size of the core. the 58XX series uses less power, sure, and probably a lot less leakage, but its also 2/3rds the size, maybe even a little less than 2/3rds.
You have more heat to dissipate, but a 50-60% larger surface area its being generated over and can pass that heat onto the heatsink. Considering my 5850 overclocked runs pretty damn cool, I have no real reason to believe a GF100 will run at 462C load, its completely possible for it to use twice the power and run cooler. Power and temperature aren't directly correlated, there are a tonne of variables and all the things that would help reduce the temp, like massive, massive, massive Arizona sized core, work in Nvidia's favour there.
But its pretty simple, its NOT faster than a 5970. If, and its a big if, they said it was 8% faster thana 5970 and left it at that, easily, there will probably be one two Nvidia made games that will work better on Nvidia hardware just enough to pull that lead, on average, it will without question be slower, significantly. Same goes for the 5870, it won't be 48% faster on average, in a couple games, maybe, in everything, no.
Ofcourse, again average could be the average over Nvidia's best games over the past 4 years, and of course, Batman AA with physx enabled

, infact those numbers are perfectly possible if Nvidia only went with physx enabled games.
The biggest issue we'll have is that Nvidia have a reputation for releases of late, where they only give cards to those that sign NDA's with clauses forcing them to ONLY run very specific benchmarks, which can significantly alter the outlook of any card.
Of course the single most obvious part, the GF100 will perform 40% faster than a 295GTX, but cost less............. lol. Sure it will be sub £300.
