It's been almost 7 years since I built my PC. It's been a solid computer, but she's starting to show her age a bit. I'd like to upgrade her but I've been out of the PC building loop for a couple years now.

​

This is my setup...

I'm willing to spend about $500-$750 on upgrades right now, but I'm also open to future (more expensive) suggestions as well.

Please help!
