Hello, I'm currently looking to replace my white MacBook (3GB RAM) with either a new 17" MBP or the 8-core mac pro. My inclination is to buy the MBP because it lets me take everything with me - however, I'm concerned about whether or not it will run Windows Vista (in VMWare Fusion) at close to native speed. My current MacBook is not nearly up to the challenge (although it appears to be more memory bound than CPU) and unfortunately its a requirement for my daily work requirements. Does anyone here have experience running Fusion/Windows Vista on the 17 MBP? Will it run with the standard 4 GB or do I need to shell out for 8 to get decent performance? Thanks in advance!
