Saved another one from going pre-built.
He said he had $1100 to spend so we went to work. He mainly uses it for games and some VR . It's one of the main things in his living room so we had to make it somewhat pretty.
Had a spare CPU cooler from my 3800x so I gave it to him for an upgrade. I think it came out better than he expected and he was ecstatic and very pleased when he saw the final product. The 3600 was OC'd to 4.2ghz @ 1.325v and runs like a champ.
Should last him a few years before needing any upgrades. I focused more on the GPU because he was a "gamer" per se.
