Wazza, almost any CPU 2GHZ or better will do for running softsynths. If you plan on using softsynths like Kontakt, GigaStudio, etc., a CPU of this size will do very well. However, these softsynths stream the samples from the hard drive as you play the notes. As a result, it is important to have 2 hard drives (applications, samples) which run at 7200 rpm and have a cache of 8mb. A good soundcard with the appropriate drivers are important as well, e.g., ASIO, GSIF, WDM, etc.

As an overall generalization, I prefer using Intel based ASUS motherboards and Intel Processors. There appears to be less problems with music software. AMD and VIA chipsets have improved so they may be a viable alternative.
