It would have made sense to choose 149USD. I recall my school purchasing netbooks and wow, those devices were quite slow. My Q6600 also ran reasonably well, though it's been a while. It's definitely not the kind of performance you'd expect at 1080p on a desktop, but I would have noticed that. Absolutely, I’d suggest doing the same. Consider a ThinkPad X250 or X260, T450 or T460—still new batteries are available from brands like GreenCell, even if the quality isn’t top-notch.
Sure, your new laptop is definitely faster than the ThinkPad T61 you're using. The newer battery from 2009 should charge quicker and last longer.
My 10-year-old laptop (Fujitsu Lifebook AH532 - i5 3230M @ 3.0GHz all core GT 620M @ 800MHz 1100MHz 2x4GB DDR3 1600MHz) handles Battlefield 3, Skyrim (with mods) and Tomb Raider 2013 smoothly... It also runs Nintendo Switch games very well with Ryujinx.
It depends on the device and available games. Some systems support older titles while others do not.
