That CPU type will be fine, subject to the processor requirements outlined in the Installation Guide here.
A new installation should be based on LMS 4.2 however, and not 4.1. LMS 4.1 will limit you to being hosted on VMWare 3.0-4.1 (see elsewhere in the same Installation Guide). LMS 4.2 introduced support for VMWare 5.
There are also a fair number of updated features and bug fixes in 4.2. See the Release Notes for the full listing.
