4x HD 7750 (XFire) or 2x 7870?

Hey guys, should I go for 4 7750s (single slots, XFire) or 2 7870s? I am coming at this from a £1k budget for a system - monitor not included. I have resolved everything but the GPUs for which I have 4x PCI-E 16x. Which set has more value for money? Thanks.

Two HD7870. Alternatively get one HD7970 3GB for now and another one at a later date:

I'd get 2 7870's. Makes much more sense in my eyes.

Also how do you get free scan postage?

Thanks. Did not know this :)

Thanks. I am a newbie so I cannot directly thank you. Thanks again!
