So with the Xeon Sandy Bridge delays I realize they won't be here until next year and I need to buy a Mac Pro this year for tax consideration so I'm looking to buy a mac late in the refresh cycle for the first time ever. I know the 6 core MP seems to be the "best buy" for most users but what about a real heavy multitasking user? With multiple Virtual Machines running? Logic would indicate a 8 core MP might be the better buy with this use case right? I have a i7 PC with 12 gb ram and it seems to use between 4 and 6 cores (hyperthreaded). I'm looking to do the same workload I'm doing now on my PC + almost double that on the mac side, so wouldn't a 8 core be better? Also, if sandy bridge only bring a 10-15% performance gain it doesn't seem that wise to wait if you simply cannot, right? Also, would the grafx card in a MP be able to run 2x 27 inch cinema display easily? What about 3? And what about 3 with 1 running starcraft 2? What about Windows 7 with aero on inside a VM with 3 x 27 inch monitors? I know there's a lot of questions but I can't seem to find good articles about MP and VMs.
