Here's my system. iBUYPOWER Desktop PC T.T SERIES NE729i. It's unchanged since 2014. I got a brand new monitor and I'm wanting to game on it. It's the Acer XG270HU. It was about $360. I only had $1100 to spend so that's $740 left. Can it be upgraded so I can game on it with the $740 I have left? I'd like to take as full of an advantage as I can of my monitor. I can stetch the budget a little if I must. I'm willing to buy used parts as well.
