I would say if your PC is a desktop that has a fast processor, and a good video card ... TS 12 would be worth buying.
You would need an excelent laptop to run TS12, one that Does Not have integrated graphics, for it should have a 1Gb dedicated graphics memory or better.
If you want all the great assets that have errors to show up ... TS12 is not capable of using them, without complex fixing of assets errors.
