Thanks. From what I've read it should overclock pretty well, and I built in plenty of cooling with that in mind.This thread and the results spreadsheet were a great help in coming up with the components shopping list.I'm going to try to avoid falling into the trap of spending all my time tweaking and tuning instead of flying (been there before with FS9 a few years ago), so I'm going to keep that overclock up my sleeve for the time being, and bring it out when FSX starts to groan under the weight of all the add-ons that are heading its way.Regards,TW Pilot.
