I have built many computers over the years for myself, for audio recording purposes. Some have been built with Intel CPU's. and some with AMD.
The fastest machine I had contained an Intel CPU (i7 2600k) a few years back, with 32 GB of memory. VERY quick machine, and I never had performance issues with it.
I built other machines since then, all using AMD multi-core processors, and have to say that I can put an AMD-based CPU and motherboard in place for quite a bit less than an equivalent level of Intel CPU and an accompanying motherboard for an Intel socket.
In fact, the online place where I happen to pick up a lot of my computer parts from (Micro Center), offers AMD CPU/Motherboard bundled deals all the time, where you can get a top-level AMD CPU and a good motherboard for between $150-$200, which to me and MY budget (being disabled), makes very good sense. The other components are not CPU based, so their cost would be the same, so overall, I get VERY good bang for the buck putting systems together for myself using AMD CPU's, rather than Intel.
That being said, the Intel CPU's ARE faster - but they ARE also more expensive, as are the motherboards, compared to a decent motherboard for an AMD socket - specially with the bundled prices available.
My AMD-based computers have ZERO performance issues dealing with audio streaming and processing for Sonar, so I will for myself continue to look at all options whenever putting a new computer together, but will likely continue to land on the side of saving some bucks going with AMD over Intel.
