ok very well, regarding the systems I want to emulate everything up to the 6th generation of consoles (gamecube, ps1 and 2, xbox, Dreamcast, etc) what are the portable ones then up to the nintendo DS and little more. I have a GPU Ati Radeon R7 2400 2gb (Would this GPU?) and as I said I have in mind the i3 series 12 (I have spoken very well of it and above is a good price) but I would also look at the i5 (what model would it be?). I'm not going to play in 4k or high resolutions, that's why I'm not sure about the components, as the resolutions I'm going to use are no higher than 1280x1024.
