[mythtv-users] What speed cpu required for encoding 2 streams and watching a third?

[Reza Naima]

I just ordered the ASUS pundit and the LeadTek TV2000XP Deluxe encoder.
I would like get a small height video card and get two encoders in the
motherboard.  The MB takes a P4 CPU.  The end goal is to encode two
streams at about 1G/Hour compression or better, and viewing a third
stream.  What is the minimum speed CPU I would need to get for this?

Thanks!
