But starting with v5, I really noticed some speed issues. Much much worse, of course, with 6.0.9 (Vicki's version.)
On 6.1.2, the i3/i5/17 machines are a good bit faster than the older single core Pentiums. These have 4 GB memory, so I do not think that this is a memory issue, but one of processor speed.
So my actual recommendation to Vicki is to spend $1000, get an i7 PC, put AC 6.1.2 on it, and enjoy the difference. If she wants to get a new server at some point, then the i7 PC would make a really nice workstation.
