I use onboard graphics these days, but before that I had several AMD graphics cards. I never had issues with them and preferred them over NVidia.
In the not to distant future, and if you still want to use a desktop PC, then there may be no other choice than an AMD based system.
Regarding these AMD SSDs. I look at it this way. Till now, the only way of getting a state of the art SSD controller is to buy either an OCZ branded SSD, or a Samsung SSD.
AMD SSDs will most likely use the OCZ Indilinx Barefoot 3 SSD controller. Bring it on, I say.
