ouch 100c... I wouldn't be happy running a card that hot. My current card reaches 36c maximum. It's a coolish running 5900xt with an overvolted artic coller though :P

Is this not correct? When did we start referring to onboard video memory as the "frame buffer", and why would such a misnomer be typically accepted and used? Do nVidia and/or ATi specifically refer to onboard memory as the frame buffer?
I apologise and I stand corrected - I've had my terminology pickled up. I did some more research myself last night when I got home and your understanding is correct. I've made the requisite change in the article. Thanks.
looks like a nice card. But 100c in passive cooling is a lot. Especialy if you put this card in a allready crowded and not much fan cooled HTPC. But i think that is not going to happen anyway, because it would not fit into a HTPC with this kind of heatsink setup. Unless you get insane with the dremel and make some 'room' for the heatsink... sticking out top of the HTPC.
If you 'mod' this nicely, this would be the 'cool' factor when you get visitors to watch your latest dvd on your 50" plasma. Your amazed visitors would proberly ask you what the strange silver ribbed thing is, that is sticking out of the HTPC hoot. You could always answer that this is the future of satalite discs. But the visitors would be look at you in disbelieve. So you tell them the thruth. And then you could watch them ROFL all over your floor...
You know the excessive heat and bland design of most cards these days is caused primarily by the excessively short product cycle of around 6 months.
If we could convince ATI and nVidia to work on 15 month product cycles the GPU engineers would be able to spin the design a few more times around the fab and hopefully get some good power savings, the board manufacturers would be able to create their own novel designs with the extra time, consumers wouldn't constantly feel shortchanged due to the rapidly shifting GPU technology, etc...
Kudos to XFX though for coming out with something original.
I know a lot of people have mentioned this already but 100c???
And, I also know that others have said that this is an acceptable temperature for a gpu core but tbh, if my 7900gt hit 100c I would probably sh*t myself!
Infact, I was worried about mine hitting the high 50s so I bought a new heatsink lol.
Tim, how were the temps measured? Just through the driver control panel?
And has anyone compared driver measurements to a calibrated temp probe (specifically for GPU's/nVidia GPU's)? I would be interested in seeing what the difference is, if any.

I've just reported the temperatures I was seeing in the driver. I hadn't seen any artifacting without a fan, but I burned myself on the heatsink when removing the card after completing all of the benchmarks. I left the card installed and went off to play some CS: Source for 20 mins and then went back to look at the temperature after quitting CS.
I then went back and did some further testing with an 800RPM fan blowing across the I/O slots.

I'm very curious about the proliferation of this term.
EDIT: Scoured around a bit more. Here are some definitions from a few folk:
I see nothing here that would indicate the frame buffer encompassing texture storage and other buffers, such as the accumulation buffer, the back buffer and the z-buffer.
To drag this one back up.... I'm just going through an NVIDIA reviewer's guide at the moment - here's a quote:
"The GeForce 7900 GS includes a 256MB frame buffer (256-bit memory interface)"
Based on that, I would say that my initial terminology was fine...
I don't think 7950 GT is much better then 7900 GT. I have XFX GeForce 7900 GT 520 Xtreme and it runs good at 600MHz Core and 1800 MHz Mem and i get over 6000 score on 3Dmark 06. The temp. does go up to 76c but that's as high as it gets.

well.... eh... right..
