You should only get that crossfire board if you plan on going crossfire later. I don't see a point in it, you'll only see a big improvement in 3dmark and on higher resolutions. -Charlie
I'm sticking with the Hiper. If anything you should do it to bycott rediculouse prices on the Antec PSU's with their 1$ =~£1 (I'm really annoyed about that today due to seeing 3 places it has happened, once on the watercooling, once on the 7900gt and another when specing a PC.)
Have a look on some reviews for the Type R, you will fall in love with it
Yeah there's nothing wrong with it, OCZ is a good manufacture. The timmings could be tighter and for £20 more you can get the platinum which has 2-3-2-5 timmings and will overclock better (at www.overclockers.co.uk) but it is not essential to get low timmings as most users will not see the benefit of it.
