I am a huge AMD fan, when they aquired ATI I pretty much stopped looking at Nvidia. ATI/AMD has had a combination of performance / price / features that made them my clear choice (at least 4000 series and after)
I purchased two 7970's at launch and im happy to report that from bitcoin mining alone they have paid themselves off and then some. I am still bringing in $100 a month mining after electric. talk about ROI!
I've respected AMD's performance competition with nVidia ,
When NVidia comes out with something that outperforms AMD GPU somehow AMD comes around and releases a product that is cheaper, scalable, greener and way faster than nVidia has and holds the spot for a while.
I respect a company that bring us inovation without hurting the pocket much
What do I like best about the Radeon 7770. Well...for me its' the next word in it's name. "Crossfire" and what that word means to me. It means I can run my 3 montiors balls-out without worry that I'll end up watching a slide show instead of smooth gaming graphics.
