I just got Altiverb for PC and I want to dedicate an old PC to it, but I'm not sure if it's potent enough and thought I'd ask opinions here before I spent any money on it (I need to purchase RAM for it).

Processor: AMD 1.6Mhz
Motherboard: Gigabyte GA-7ZXE
Memory: 168pin PC-133 SDRAM

It will be completely dedicated to Altiverb, nothing else - do you think it's a fast enough processor? Think I'll be able to run TWO instances? This is what I'm really concerned about, their specs say 1Ghz proc is minimum

Also, I can put up to 1.5G ram in it - do you think 1.5 is overkill, and that 1G is sufficient? It's only $35 for 512MB.
