A minimum of 1GB GPU memory and use of the most recent Nvidia drivers, AMD drivers, or Intel drivers is recommended. TouchDesigner uses OpenGL.
A: TouchDesigner runs on laptops, desktops, and
rackmounts. You don't need to buy the fastest CPU, but CPU clock speed
is more important than number of cores. Get the best Nvidia graphics
card with the most graphics RAM you can afford. TouchDesigner can use a
lot of CPU RAM, so get as much as possible.
Really, the right GPU for you would depend on your budget.
