The ATI name needs to go. I associate it more with their bad products in the past and associate the Radeon name with many successes. Tons of companies are named ATI regardless.
AMD is a good brand name, just (as with any brand) could use more promotion and an even better brand name. AMD made the legendary Athlon, and there's nothing wrong with the Phenoms, I just built one and would have no qualm using one. They make good stuff. Nvidia's wishing they were making x86 CPUs, that much is sure.
I hope they stick with the green logo for AMD. As far as the video cards, it doesn't matter, Nvidia's going to be pushed out of the x86 market completely by the AMD/Intel alliance since they continually attempt to prod Intel (lately with the shouting about ARM). This is a company I wouldn't bet on, buy from or hope to have support from for too many years to come.
