6970 Crossfire

[Fruitbooter]

Building my first system soon and have been offered a pair of 6970's (not sure what brand) for £100

Would you say this is a good deal and what sort of performance could I expect?

Or would it be better to pay another 80-150 and get a newer single gpu?

Thanks

I was thinking Corsair 600t, 750w Corsair psu and Gigabyte Z77X-D3H
