I'm putting together a bitbucket for home, and intend to run 1 virtual machine on a regular basis with other often as experiments on what will likely be a 64bit Server 2k3 host. Intel E2140 / Intel E4400 / Intel E6320 2 gig DDR2 Gigabyte GA-G33M-DS2R 1 x 300 gig SATA OS / SWAP 4 x 500 gig SATA RAID5 on ICH9 IntelMatrix Antec TruePower2 480w I'll likely use VMware at this point for familiarity's sake. My question is weather or not it is worth getting a CPU with hardware visualization, and how significant a role will cache play. The machine will be infrequently be serving a large volume data, downloading and folding whilst occasionally playing host to experiments in virtual machines. Is it worth the extra $70 for 2 meg cache over 1 meg? Is it worth an extra $140 for 4 meg cache and VT? Appreciate any knowledge and experience you people are willing to share.
