I don't know if this would be much help to @Jason Carr but I've notices a small bit of a trend googling the different CPU's and it seems that most of the CPU's that are having the most performance issues her all have 1mb of L2 Cache, which when split across four Cores really is only a quarter of a mb of L2 cache per core. Take my computer its CPU is a lowly Dual core E7300 yet runs LaunchBox/BigBox flawlessly but yet it has 3mb of L2 Cache, which in essence is 1.5 mb of L2 cache split across 2 cores. This is just an observation of course and i might be completely wrong.
