First I put you in situation:
OS: Win XP SP.
PC:
Videocard: Sapphire HD 3870 X2
Processor: Q6600 @ 2.40GHz
Mainboard: GIGABYTE DQ6 X38 (Latest BIOS on Gigabyte website)
Memory: GeiL BlackDragon DDR2 2GB @ 800MHz
Soundcard: SB Live 5.1
PSU: Thermaltake Toughpower 750W Modular
Everything at default clocks.
When playing Crysis on very high (DX9) settings my PC shuts down at some point between 5 minutes and 10 (random). Other games that cause shutdowns are COD4 and the Racedriver GRID demo.
Things checked:
-I have the 6pin + the 8pin connected.
-I have the molex cable that supplies extra power to the PCI slots on the motherboard connected.
-I tried CAT 8.2, 8.3, 8.3+hotfix and 8.4 (using Driver Cleaner when deleting).
-Temp goes at 81ºC max when auto, but I tried with the fan blowing at 50% and 100% constantly with RivaTuner and it still shuts down.
I remember I played Crysis on very high (DX9) settings with my 8800gt for hours (rest of components where the same) and it never made my PC shut down just like if someone pulled off the power cable out.
Now the drama:
I asked at the Sappiretech forums and basically they told me that my PSU isn't enought for a 3870x2.
Read the history here:
SappireTech
At the same time, I asked at the guru3d forums and they said exactly the opposite.
Guru3D
As you can see, there was a confrontation and that G33ngecko guy banned a guru3d member that tried to dismantle their "you need a PSU with more than 20A on the 12V Rail" theory.
At this point, i've tried plenty of things, like downgrading the GPU, set a bit higher the CPU voltage, switch RAM slots... I always get a shutdown. An interesting thing is that it only aparently happens when Catalyst AI is set to Standard or Advanced (Crossfire is activated).
Already tried without the extra HD and DVD and case fans to leave all max power possible to the GPU. The thermal options in the BIOS are all OFF.
I got Everest to log everything while playing GRID with A.I set to Standard. It shut down after 1 minute 20 seconds and here are the stats until that point:

Im totally left of ideas for things to try and I cannot swap components since I don't know anyone with a PC that has PCI-E (not gamers) and don't know a store where they will let you test stuff (at least without paying).
I don't have many options left besides:
RMA'ing card.
Buying another PSU.
But both things will cost me money and time, which means I need to know WHO is right (Sappire tech forum or guru3d forum).
Thanks all.
