where in southern scotland?
Mathwat: At the border, 15 mins from carlisle.
Sorry if this has been mentioned earlier but I don't have time to go through all the posts right now.
I had a similar situation in the past, in the end it turns out that I just had a faulty cable. Also have you run a stability test to scan for artefacts or defects? If not I'd recommended doing so.
So 6850 V GTX460, Am I right 6850 offers more frames ? (Than 1GB GTX460)

Not strictly true. Depends as always on the game you're playing and your settings etcetc.
Bit-tech's review of the 6850
The GTX 460 and HD6850 are so close together the biggest difference really is that one has PhysX and the other Eyefinity.
Best of luck and hope you finally get this problem fixed!
EDIT - also, the 460 generally has a quieter cooler
