I bought this card before realising that there is a £30 cheaper version, which is factory over-clocked, and can be pumped up a fair bit from there.
Amazon were great; they advised me to refuse the order of the new shape standard card, with the 2 mini-ports (This, the Sapphire 11200-07-20G Graphics Card (2GB HD7850, GDDR5)) and order the older shape, x2 DVI x2 HDMI but superior in every other way Factory OC Edition ( Sapphire 11200-14-20G OC Sapphire Card (2GB, HD7850, GDDR5).
Less a review, more a tale of experience to save others. The two cards only difference on Amazon is the two letters 'OC'. Other than that the details are exactly the same. I didn't notice it, and I would like to save others.
Physically the only difference is this new model has mini ports, and a slightly rounded shape. I would recommend paying £30 less for the far superior factory over-clocked edition, unless you are jonesing for mini ports, in which case probably the MSi card is more for you.
Hope this helps everyone!
