I'm thinking about upgrading to a new machine with a Q6600 processor OC'd to 2.93 ghz. Currently have Radar Contact, Flightsim Commander, Active Sky and FDC networked to a client laptop via wideclient. I know that neither FS9 or FSX will use all the Q6600 cores but can the add-ons run on the unused cores so that I can eliminate the laptop but not suffer a performance hit.Any advice is appreciated.ThanksJeb

If you have a dual core now, after initial load up it can handle FS9 or FSX + addons without a performance hit while running. Quad core may be the future, but dual core does the job quite well for FS for now.Gary

Thanks Gary...no I currently have a P4 3ghz Dell Dimension. Runs FS9 pretty well, FSX not so good.Jeb
