You're right, looking at the tech specs both the BFG cards from Scan and Dabs are the same:
dabs.com - BFG Graphics GeForce 8800GTS 512MB GDDR3 PCIE Dual DVI (BFGR88512GTSE)
£167.39
Computer hardware and software at amazing prices, available online from Scan Computers UK
£163.31
Of course neither have one in stock yet....
I'll get mine from Scan as I get free delivery.
I think this is the card to go for so good call.
