for upscaling in emu's like pcsx2 its your GPU that is used, so that is your weakness with the specs you posted. That is only for the 3D based systems though, all the older systems only use the CPU and usually just the one core, so you want a high clock speed there, i see yours is at 3.0GHz that should be fine for most things but will struggle with some emus, higan and beetle saturn retroarch cores for example. i see its ai5-4590s and a GT730, is it a Laptop?
