Look you talk rubbish, if you think the 2900 runs the cooler than the G80 series then you are lying through your teeth, as some of you fan boys are in denial.
actually, you'll find not every single gts runs the same temp, thermal paste can be better or worse on some cards, the core itself can run hotter because its from a poorer yield or for other reasons. they can all run differently, just like you can get a hot or cold gts, you can get a hot or cold 2900. my 2900 on air ran about the same temps as my gts load, which somehow ran a fairly similar temp to my gtx despite using more juice. thats life.
also in general overclock gpu's is mainly a 3dmark thing, you might find that increase aa one more level is possible with a small overclock, but you'd very rarely find that a small clock would allow a higher detail level, or to go up a resolution and still have playable framerates. but most cards don't clock very high. if with a bit of voltage you can go fro 743 up to 1000 that isn't a small overclock, likewise 825 mem up to 1000, or even more isn't that small. so many there is some point.
when it comes to reviews also, one site said, looky here, if i turn the fan off completely, it can hit a massive 100C
go stick your finger on the g80 fan while its running 3dmark and see how hot it gets. some of the reviews made me utterly cringe from their not only bias, but ridiculous claims they came out with. essientially they said "look with no cooling this hot thing keeps getting hotter, so its crap".
as i've got watercooling on my r600 which gives it 39c idle and about 45 load at the moment, i'll try some voltages, might have a quick read on xtremesys to see what volts people have tried.
