I'm wanting to put together a new ESXi server (my first, actually), to just run some simple VMs to provide services for myself and my roommates (AirVideo for their iPads, Subsonic for music/movies for my Android stuff, an XBMC database/updater VM, etc.), so I'm probably going to go for consumer-level hardware to save money, since this won't be super critical stuff I'm running- well, that, and I want to fit it all into a micro ATX case, which it is not that easy to find server motherboards for.
I originally was set on waiting for Bulldozer, but I'm not really sure how the whole two-cores-are-one-module-sharing-stuff thing will impact VMs (that and I'm getting tired of the continued delays from AMD). If I get an 8 core Bulldozer CPU, would the fact it's not really 8 "cores" drastically impact performance if I'm, say, transcoding and streaming two or three 1080p movies at once inside VMs? Or would I be better off buying a Phenom II X6 1090T for its six real cores (even if it is old tech now)? Or, to rephrase: how drastically will the changes that AMD is making with Bulldozer in terms of it's core/module dynamic impact virtualization?
