Well this card has been tested again by Scan, and No fault found.
This is from my RMA ticket:
"I guess I can leave it overnigh. TBH - this is two different tests - two different boards - different O/S - different games - DX10 and 9c - the card is fine. Whatever is causing it is isn't the card. And I doubt it is incompatible. An open bench is worse than a case. The heat can't go anywhere, it kinda sits in a pocket and they get hotter and hotter. At least in a case there are fans shifting and circulating the air.
Scan diagnosis Ran Colin McRae Dirt as requested - did a few laps then left the recorded demo looping all day. It has been on for at least 5 hours now without a break. Tried all the different camera angles. All Gfx settings are the max possible and 1280*1024. AirCon is off - it is roasting in the room today - no need to put it in a case. That isn't feasable anyway. The card is blowing some serious heat out of the fan so I know it is well and truly loaded."
They weren't prepared to do anymore - which is fair enough, they've got other customers aswell.
Shame higher resolutions weren't tested - I never had a problem at 1280x1024 on any app, also the bit about the cooling is just plain wrong. An open case will be cooler for this card - as its got an active cooling system (so will suck air in). The stagnant air thing is only an issue with passive cooling systems. And to say heat isn't an issue as its "blowing some serious heat out so I know its fully loaded" errr this card idles in the 60'cs so its always hot you can always feel heat out of the back.
I'm just gonna cut my losses with this one and take it back, better the devil you know they say. Adjusting the fan speed with rivatuner is no big hardship I suppose. At least the card has never produced artifacts or such like poor Paradox's did.

Scan have offered to send it back to XFX but the whole time frame of that is anybodies guess, plus what if they find no fault ?
This whole charade with this card is begining to effect me and its just not worth it for a poxy graphics card. Some people out there have REAL problems, and i'm getting up in the morining/going to work thinking about that POS graphics card. Its just not normal.
I've learn some lessons and will know next time to avoid XFX like the plague, and any single big purchases like a £500 card will be done at a local store only, so any problems I can physically take it back myself.
To conclude with A big salute to all the Scan returns staff who have worked hard for me on this longwinded issue and in particular Phillipp who has truely gone out of his way to help me.
Now Roll on the 9800's.............
