I'm running Quicken on a 1.4GHz dual-core Intel Core i5 (Turbo Boost up to 2.7GHz) with 3MB shared L3 cache with Windows 10.  I have no idea if I have TurboBoost turned on. I'm not running anything else on that laptop besides Quicken. 

Quicken can't handle it any more.    It was doing ok up until about a year ago until the new updated version came out.  I'm assuming Quickbooks would have higher requirements than Quicken.
