I've looked at review after review of different brands and versions. One complains about the Gigabyte Windforce edition having no heatsinks on the VRM, posts on a different forum say VRM gets too hot on the Sapphire Vapor-X version despite having heatsinks, MSI seems to have a bad reputation after the 660ti overvolting ordeal, etc.
It's hard to know what to trust. I'm certainly at a loss as to what brand/version would be best in the long run (with no overclocking).
I always go Asus,MSI,Sapphire for video cards and have not regret it yet.I think you already did the best you can do and that's read professional reliable reviews people on public forums will give you bias answers.
