After my previous upgrade, my graphics card has been overheating. From 75'C under load previously to 125'C (where it throttles itself and everything lags) now. The fan on the graphics card is still running, I've even put a case fan underneath the card to try and cool it but it still reaches 125'C... It's not dust and nothing has changed on the card itself, the heatsink and fan is still making proper contact with the card itself. I didn't break it :D

Time to replace the card (since I don't want to shell out on aftermarket graphics card coolers)? I might just buy an 8800GT...
 
125'C is a bit high for a 7900GT i must say, but a Card usually underclocks itself if the powersupply isn't sufficient.

If a card overheats, you'll start seeing "artifacts" wich is basically little white Triangles or weird lines over the screen, when you play games.

U sure the card is a real 7900GT (not a firmware flashed 7800GT wich in turn means its overclocked)

Yes I'm sure it is a 7900GT... I've been monitoring the temperatures. It reaches 125'C, everything lags for a while, the temperature drops to 110'C, the temperature rises to 125'C, everything lags for a while, etc, etc...
 
Check too see if the HSF is seated properly... pull it off and reapply some thermal paste and slap the sukker back on
 
Do you see any Artifacts on the screen though??

Cause i think the 7900GT's chipset has a automatic Safegaurd for overheating.
(hence the automatic underclocking)

U don't have any special overclocking or Boosting Drivers for that 3dcard??

Cause my one buddy had 3rd party drivers wich basically boosted the speed by overlocking the card and automatically clocking it back to normal once the card got too hot.
 
No real artifacts that I've noticed and no special boosting drivers. I use NVIDIAs stock drivers (162.18) and don't overclock my graphics card...

Yeah, it's so fast that the graphics card has to try overclocking itself to keep up, hence the overheating ;)

No, your graphics card throws up because its in such close proximity. Your Quad has given your card an STD :sick:

:p

Either the 8800GT or the new 8800GTS

For the 8800GTS it all really depends how much higher it scores in the benchmarks. Is it coming out in the 320mb and 640mb versions again because the old 320mb had certain RAM issues with some games.

Don't really know... I think an XFX 8800GT XXX edition would suffice, though :)

24th November is a day to remember (If the graphics card arrives when its supposed to I will have a new computer). Hey who wants my Athlon 2800+ and Nvidia FX5200 :P.

GPU's will slow down when overheating, it's called throttling, that's why you have those slowdowns until the temp drops enough then it speeds up and temps rise again.

This isn't serious and you don't need to get a new car (if you don't believe me and still think it's buggered and that you have to get a new card I will happily pay for postage for you old "broken" card to me)

The two most likely reasons are, the heat-sink isn't making proper contact with the core or the fan isn't going fast enough because of software or is malfunctioning. You could quite easily fix either.
