Replacing my wife's 10 year old PC.
That machine was running Intel Core 2 Duo E8400 3GHz (Wolfdale), Gigabyte EP45-UD3L Mobo, Corsair 4GB DDR2, Nvidia GeForce 9800 GT 512MB, Windows 10 (64bit). This machine was explicitly built for her to play TF2.
This new one is for her to play Overwatch and stream 1080 content.
Lol definitely agree it's overkill for Overwatch. But like the previous computer she had, we plan for this machine to last her a decade as well. Maybe in that sense, not so overkill, i hope!
