VST 2 vs. VST3 versions of Neve Portico Plug-Ins

Thanks for the replys.

If EQ or compression is used on a track throughout the entire length of the project are there any benefits/disadvantages between using the Portico VST 2 vs. VST 3 versions?

The reason I ask is the computer system I am using is approaching the limit when using multiple inserts of these plug-ins (along with everything else that is loaded in a given project). I’ve held off moving to a new Win7/Cubase6 system because all is well with the “old” system (XP/C5).
