Thanks for all the replies guys.
Since the vast majority of you reckon that POV are basically ok I've changed my order over to them with SCAN on the understanding that should the EVGA cards come into stock before they start the build that they will amend the order accordingly.
The two sales guys I spoke to at SCAN were also very positive about POV and from what I understand they insure the cards for 6 months and POV will cover them for 3 years which is as long as I'm likely to have them in my main PC for anyway.
I have a feeling that it could be quite a wait for the EVGA's and I really want the PC before the summer starts
