1. Brand :: Any as long as its reliable and easy to obtain drivers.
2. Budget :: Nothing more than 4-5K
3. Specs :: Lots of RAM. Something long term, plan to use primarily for lots of virtualization, testing, messing around with software, downloading, light gaming (eg: DoTA, Unreal Tournament 2004, nothing super recent)
4. Size :: As light as possible. I move around alot.

I would greatly appreciate if someone could kindly provide some valuable advice for me. I am stuck in that, I am not sure if I should just wait for the new Intel processors or buy one now.. Any advice would help me out tremendously. Thanks again
