Ok if anyone wants to chime in with any suggestions that would be great!
Looking for a pre-built computer: would like to keep it under 1,000 if possible. I'm interested in emulating old games, up to PS2 and Gamecube if possible, and playing games that aren't easy to play on console: sim, building, etc. I may want to play more demanding games if the PC can handle it! I would need a keyboard and mouse, and I plan on hooking it up to my TV.
I had an ASRock P67 Pro3 with my 2500k and it worked very well for about 6 years before I sold it. No complaints there. I've been using an ASRock X399M Taichi for about two weeks now and it has worked flawlessly as well, albeit that's a short amount of time to test it.
