Faster Cache is good to have, but the CPU and the RAM is where it really counts. Then top that with a fast SERIAL ATA hard-drive and you have a good system going. Since LE is very much CPU dependent, the faster BUS speed chips and chipset will get you where you want. Do not focus on the "cache" alone. Bus speeds are your pipeline and the Hard-drive speed is your carrier as well. As for the Bartons, I am really not sure. I run a Athon 3000+ and it is fine. 1 gig of ram and I am set for all that I need to do really. - Doc
