I build PC's for a living, supplying a number of business and schools. I have based this on AMD stuff as that is what I know, they work very well and tend to offer a few more features at a given price. The computing industry is going multi-core, and as software catches up AMD's stuff just gets better.
If I were to go with an AMD CPU would I be best off getting an ATI GPU too? I just wondered, with them being from the same company, if there's any benefits? I'd rather have an NVidia GPU though, if I'm honest, as the Linux drivers are much better than the ATI ones.
