Any idea if you can get a quad core into the T420 itself ? I have a dual core i5 that is still doing decently (probably because they still sold i5 CPUs with hyper threading back then) but a quad core 35w CPU with HT would be a great pair with the dedicated Nvidia graphics.
Some person on Web says yes: https://forum.thinkpads.com/viewtopic.php?t=133646#p864052
There's also the W520, which looks like a T520, but is set up for a larger PSU, and had quad-core and better GPUs as factory options. (I own a few each of T520 and W520, but don't like the huge power bricks of the W. So I'm using the T as daily driver, until I really need something in the W.)
