Something like Ryzen 5 / high i5/low i7 with 4060Ti or 6800XT/7700XT. I think you’ll be better off going a bit higher than that. But then again, a pc does more than just gaming so if you would want it just to game with a console has better optimisation for lower price.
I thought I saw Zampella from Respawn saying stuff about it. All we need is for it to be Titanfall x Battlefield 3
Edit: It adds up to what one might call classic Battlefield, but bigger — big enough that it merits the efforts of four separate studios in DICE, Motive, Ripple Effect, and Criterion (Ridgeline Games was briefly part of its development before being shuttered after founder Marcus Lehto’s departure). EA CEO Andrew Wilson claims it’s one of the “most ambitious projects in [EA’s] history.”
