Turn down your CPU OC then test it at it's preset clocks, this should free up some power draw and enable you to rule out your PSU as the culprit.
Also: I'm not going to be so bold as to say your OC isn't solid, but somtimes they can still have issues. My CPU OC holds up to 8+ hours of prime and lots of runs through IBT yet source games sometimes stutter unless I reduce it to 3.4.
I'm pretty sure it's the card and the competitor didn't stress it enough or they put the fan at 100%
Sorry - you're limiting the fan speed? And you're surprised that it's shutting down? I did post above that I had an XFX XXX and it was incredibly hot and the the fan ran 100% and noisy the whole time. That's part of the deal with a heavily overclocked card like this.
Have you tried RMA'ing to manufacturer?
lol, You're not expected to force the fan at 100% on a factory OC'd card. Fan speed is automatic based on temperature. If a factory OC'd card requires 100% fan then it needs to be RMA'd. I'm not limiting it, It's not supposed to be at 100%!
BFG only go to 675MHz with water cooling, so you'd have to question why XFX thought the stock cooler could cope?
WOW, MIGHT HAVE CRACKED IT!
ACCORDING TO MY GTX 280 BOX, I NEED 40A ON THE +12V RAIL. FROM LOOKING AT THE SPECS OF MY PSU ON THE ENERMAX WEBSITE http://enermax.de/en/products/power-supply/infiniti.html IT APPEARS TO HAVE ONLY 30A. IS THIS NOT CRAZY RUBBISH FOR A 720W PSU? ANYWAY, IS IT IN FACT 90A BECAUSE IT COMBINES THE THREE RAILS OR WILL I INDEED NEED TO FORK OUT ON A TX850. AT LEAST I'LL KNOW.
Sorry to burst your bubble, but there is no way that a 720w PSU can combine 3x30 amp rails into a 90amp 12v rail. Try it, and it will go bang, or at the very least shutdown. 90amp x 12v = 1080 watts!. The label on the side will probably tell you something like combined maximum watts 650, or whatever.... Anyway, its nothing to worry about, your PSU will still easily handle an overclocked 280GTX.. Trouble is XFX suck, their testing is terrible, and they will slap overclocked stickers on cards without actually doing much testing, and their support/RMA is dreadfull.
However, if its stable at stock speed, it should be fine, or at least just as good as any other stock speed 280gtx. I certainly wouldnt bother selling it and getting a 260.
I take it that's a joke? My loan comes in one day and the whole thing goes on rent the next day.
I would look at reducing the OC on the card in small increments to find out what its maximum stable OC is
it really sounds like the card is not able to support the preapplied OC XFX have applied.
Once you can prove it is stable with a smaller OC you can send it back requesting either a replacment or refund stating that the product is not fit for purpose ie it doesnt work properly as stated on the box/manual.
Thanks. Good advice. If i can get a refund though I can probably afford a GTX285 stock or 4870x2. worth a try i reckon. I'd hapily stick with this card but i'll always be wondering if those crashes are down to it.

RMAing to XFX is akin to sitting in a bath of dog faeces. Not pleasant and best avoided. Hopefully i can convince the competitor to reconsider a refund
As stated in email, offer is still open to pop round mine at the weekend, or me to yours, to test it in another mobo
With the long hours at work atm, I cant do mid week.
For someone with your setup in your sig then I think at least one of your loan payments has gone in the direction of buying computer equipment
Or was it mumsie and dadsie got it for you?
