Hardware recommendation request

[John Hayward <John.C.Hayward%wheaton.edu@localhost>]

Dear NetBSD Xen People,
   I will be getting a new computer soon and am pressed for time and I 
know people on this list will have good recommendations.  I am pretty
much restrcted to desktop which are in the HP line.
   My concern is that there is a 4GB address limitation with 32 bit 
addressing.
   What chip and motherboard would work best with NetBSD-Xen to support 
more than 4GB of memory to allow a reasonable number and amount of memory 
for DomUs?

TIA
