I'm going to build my own PC pretty soon and I need some help with the parts. The kind of PC I'm going for is an emulator PC. A PC that can easily emulate NES, SNES, Genesis, Genesis 32X, every type of Gameboy, N64, DS, Gamecube, Wii (maybe Dreamcast, 3DS, and Wii U) games without any slow down, lag, freezing, buffering, and viruses. But I don't know what parts are the best for building an emulator PC. If you can give me a list of good parts or a video please reply. I'm looking for a $2000-5000 budget. If you have additional questions, just ask. Thank you. Please include: whether a single, double, triple, or more monitor set up is best, kind of monitor, keyboard, mouse, headphones, and a desk & chair set.
