Mag, I don’t think memory’s the big clincher in this software. Most of the power draw is from the CPU. Best bet is Intel Dual-Core or better. Although I saw a major improvement in stability and clean sound going from a p4 2.6ghz (non-HT) to a p4 2.8 Hyper-Threading CPU. I was amazed!
Athlon CPUs will work but Leif’s code is built upon the Intel feature set and takes advantage of it.
The other key hardware is the sound card.
Hope that helps at least some.
