Every computer I've ever built has alwys been a price/performance machine focussing on
it's use. My current studio PC is a 6 core AMD. At the time of purchase, the CPU was 40%
the price of an i7, so it was a no-brainer for me.
And guess what? I have loads
of audio tracks, compressors, limiters, amp sims, reverbs etc. and the CPU sits at about
15% load.
I'm glad I didn't spend another £150 on the i7.
