virtual appliances CPU/RAM/performance

If you want to run a bunch of CSR1000s, and/or virtual appliances from other vendors for lab purposes only, is the speed of the CPU important? Or could you just get a cheap CPU and just spend your money on more RAM instead?

You will want as many cores as you can reasonably afford if you want to run these things concurrently. A Quad core desktop processor is not that expensive these days.

Maybe I should have been more specific. Is there a benefit to anything faster than a mid-range quad core consumer grade CPU? I essentially would only be running the control plane so I can't imagine that CPU would be a major factor, but there's also the issue of how gracefully these virtualized routers handle being CPU constrained.

I don't know about CSR's but running Dynamips with 16+ routers (3725 with advanced image) and i get about 15% CPU on a mid range laptop.
