I am going to buy a new PC to run Adobe Creative Suite 5.5. Underconsideration is the HP Z600 or Z800. I am also considering a custom built PC. Don't yell at me for not going with a MAC, I have my reasons. In studing the CPUs that would be best for doing light weight video editing to multimediadesign the list is very confusing. Could anyone make a suggestion for best performance and why.
