I'm coming from a X4-860K with a 750ti......so this might be a little better. I don't play a lot of games, mostly FFXiV and Overwatch.
I can have multiple tabs open while gaming with no lag/stutter, so good for me.
CPU- It's like night and day.
Cooler- I just like how it looks.
Motherboard- Super easy, no problems and more than enough for what I need. MSI Mystic light works but it seems like they half-assed it compared to my sisters ASUS. Got it with CPU bundle at Micro Center.......good price but I had to drive to Houston, next time I'll probably pay extra so I don't have to do that again.
Ram- Really the only thing I'd change, but I got it on a Google Express sale.
Storage- Got the M.2 to see what the fuss was about and while my PC boots up super fast, I'm not sure it was worth it for me. Using another SSD from old PC.
GPU- Love the look.
Case- I originally wanted the NZXT 500 for the simple reason of the front panel connector, but I'm happy with the Fractal. It was easy to build in and I like the mesh front.
PSU- 650 watt might be overkill for me but the price was really good....sister got it for me. (All the $0 prices were gifts)
Case fans- I love the simple ring and that they aren't overly bright.
Cable extensions- Better than I thought they would be for the price.
The build was super smooth and Windows booted right up. I'm super happy with the outcome and can't wait for the next one.
