Soldato
Bit like RAM really... I'll happily recommend brands other than Corsair, but if I was parting with my own money, I'd much prefer to pay the slight premium and buy Corsair, despite the fact that there is very little reasoning behind it...

GPUs are very similar to ram. Given that they are usually made by one or two manufacturers (Elpida or Hynix) and then just have something stuck on them before being sold as a branded product.
Heatsinks on ram have been pretty much proven to be a waste of time, yet, it's quite amazing how much value they seem to add.
I also usually pick Corsair products. Not because they are better than others, but simply as I have used their warranty service and they are excellent.
Mind you, they are in every way identical to Patriot's products given they both reside in Holland
It all just comes down to warranty in the end.
