I don't understand why people have problems with AMD drivers, I've never had any major problems with drivers from either manufacturer personally. A friend of mine has actually had far more problems with Nvidia than AMD.
They are right as well, the HD 7850 2GB is a lot better. It consumes far less power and performs a bit worse than the GTX 570, a lot better than the GTX 560.
A CX430 is enough, if you can pay the parts in ncix.ca (from canada), it's worth, the corsair cx500w is terrible overpriced in newegg.ca, in ncix you can get a xfx 450w (made by seasonic) for much less, if not good luck with your build.
