(please don't say OCZ or thermaltake) The voltage regulation/current supply is the issue, not the wattage, and with such a high wattage running at what is almost inevitably such low efficiency the voltages are far more likely to go out of spec.
If you suspect a faulty card I don't see why the 4850x2 won't help you troubleshoot. 7850 TDP 130W, 4850X2 TDP 220W; 90 W isn't going to make any difference to power issues when you're going to have about 700W spare capacity anyway.
Whats the RAM?
Its a Corsair PSU and its actually only 860 the previous was 600 (I remember thinking 1000w was overkill at the time but was looking at both) The reason I wanted a similar card was to test as close as possible to the same settings etc.. if I'm honest I know for a fact its not the power as I hooked up the old PSU just to the gfx card once I put this one in and it still bombed.
Specs
Mobo - Asrock Z77 Extreme6
CPU - Intel Core i5 3570K 3.4GHz
RAM - 16GB Corsair Vengeance DDR3 1600Mhz CL9 1.5V Non-ECC Unbuffered 4x4 sticks
The setup I have is with 2 monitors one from the graphics card via DVI and the other is directly from the mobo using the inbuilt intelHD(I need new monitors really but can't justify that as I spend more time working that gaming these days and if I want 1080 gaming action I can just run the HMDI from the graphics card to the 50" TV and use that!) however when I did the reformat I didn't install the intelHD or the second monitor and ran the PC and again still died.
I was originally convinced it was the card being faulty I've tried some of the fixes people posted about the catalyst control center causing issues no luck, I even
reformatted and just in case it was corrupted drivers but after posting on another forum (sorry!!) they convinced me my old PSU was out of spec and old although I didn't think so (was made by Hiper) but again spending £50 on a PSU isn't the end of the world especially as I needed another one for my test environment anyway as that was running on some old 300w PSU that died in a blaze of glory due to overheating.
I also ran memtest on the RAM and there was nothing there, I couldn't find an app to test the GPU RAM.
I'll give the 4850 a go and try to stress it out and see if it BSOD's
The only external factor really is that the base unit is plugged into a UPS that shared with 2 Monitors and a NAS but again being logical if it was to do with that I would assume I would see the other devices fail more, plus the PC stays on and the sound keeps looping just freezes up, the CPU fan keeps spinning but the graphics card fans all stop and for all intents and purpose its dead until I reboot, its looks like an overheat but if i'm running a monitor it stays well within normal temps, even the GPU load doesn't seem to matter I've had it crash when its been running at 99% for half an hour and crash when its at 40% for 10 minutes.
Just because I don't care doesn't mean I don't understand.
