I've paid a hefty deposit last week for my new build (link to it here) and have just now been told that the Gigabyte HD7850 I initally ordered won't be available for about two more weeks. I now have to quickly decide between the two remaining options: Sapphire HD7850 OC or PowerColor HD7850.

The Sapphire one is the only one that has a fair amount of reviews, while the PowerColor and Gigabyte ones haven't been reviewed even once, anywhere. There is also a substantial difference between the Sapphire OC and the PowerColor one, firstly the core speeds (920 vs 860) and secondly the cooling mechanism. While the Sapphire looks way better with two huge fans and the PowerColor one has one scrawny fan, it does seem to work better with my case (which has only one 120 mm front fan sucking in and one 120 mm fan blowing air out the back) since the PowerColor is the only one that blows air right out the case instead of mixing it up inside. Or so I've been told by the guy from the company who will be putting it all together.

I now have about 12 hours to decide whether I want to wait it out for the Gigabyte to be available again, or whether I want to switch to the one remaining Sapphire in Slovenia (seriously, one card remaining in an entire country!) or pick one of the four remaining PowerColor ones. Prices in € are about 260€ Gigabyte, 272€ Sapphire, 240€ PowerColor.
