Built this for an old friend who has been suffering with her Macbook for the past 5 years. She used to be into TF2 heavily and played WoW, but ended up having to focus on school and couldn't game that much. Then Overwatch came out and she started playing on someone else's computer and got hooked, but had no system of her own to play on. I already had half a computer in spare parts hanging around and would love to enable someone else's Overwatch addiction!
I ordered the processor, RAM, and mobo off eBay for a pretty good deal, and then had the GPU, PSU, and hard drive/OS already in my collection from Craigslist PC scavenging. I picked up the case on Amazon for $33.00 and it seems like it has some nice features for a budget case, and the size is great. The prices listed are what you can expect to pay in the used market for most of these parts, although I already had some in my possession.
This rig plays eSports titles with ease, which is the goal. I've tested it with Overwatch, CS:GO, and Fortnite mainly and it can handle 60 FPS at 1080p on Medium/High settings depending on the title. I would have liked to go with something more modern like a Ryzen APU system for the upgrade path, but the price of DDR4 was prohibitive, especially since I'll be donating this build for free! I've really been impressed by the performance, and would recommend a build like this to any 1080p gamer on a tight budget.
She is stoked!
