The TDP on your video card is 71 watts but is only directx 10. If it was directx 11 it would run middleton for laptops without any problems giving around 22-30 fps. You CPU does support 64 bit but you will need a 64 bit operating system. If you're running win 7 or later you should still be able to upgrade to win 10 for free and I seem to recall win 10 64 bit is free from 32 bit. TANE runs the CPU less than TS12 by the way so its not so important.

You should be able to just drop in a GTX 1050 TI since it draws a tdp of 75 watts, not the fastest card but TANE is runnable with it. Faster video cards would mean looking at your power supply etc.
