It's possible, not ideal but possible. If you read my original post and OPs original post he didn't state a budget and was mostly talking about emulation.
You could probably play next generation games with your budget. You don't need an i7 get an i5, get a good GPU like a GTX1080, 8gb DDR4 and your set for a good 6-7 years.
I recently bought a Ultrawide Monitor and I'm completely in love with it. 21:9 aspect ratio is so much better than I thought it would be for gaming and movies.
