I can validate this outcome: I recently re-worked Ellyn's Haswell PC-- which she no longer needed due to the 7700k/GTX 1080 behemoth I built her-- and sold it to my sister-in-law.

It's a 4670k, with 24 gig of DDR3, and an 8 gig RX480 (I bought her the card for her birthday, got a steal of a deal from Micro Center), on 64-bit Windows 10. "Mass Effect: Andromeda" runs butter smooth with a mix of high and ultra settings, at 1080p. Incidentally, she's loving the game, from every possible angle. I watched her play for a couple of hours, and it's now next on my list of games to buy and review.

And while we're on the PC note, one of Ellyn's friends recently bought a GTX 1080, and she gave me her free game code. With it, I redeemed "Ghost Recon: Wildlands". I'm running the game at 4k on my Haswell/GTX 1070 duo, at high detail (but with shadows turned down), and it's a rock-stable 30-40 fps at all times. It's almost like a dream game for me: GRAW in an open world setting? Sign me up!

When the second wave of Ryzen hits on April 11, I'm going to build a Ryzen 5 1600 system. I already have a buyer lined up for my current PC, so the new system is only going to cost me $230 in net.
