For those of you who can't or don't want to drop 1500 bucks +, I think you'll still enjoy a good experience. It 'seems' like this sim will not be like the others where you needed a machine that has not yet been invented to run at max sliders.
I did build a new machine - not exclusive for the sim but partly for that and partly b/c my old rig is a 2009 Core2Quad. Costs roughly $700 and I think the specs will allow a good experience (I hope) although maybe not to the level of the eyecandy i'll see here and elsewhere.
Core i3-10100 - air cooled
EVGA Bronze 450W PSU
GTX 1660 Super
32GB DDR4
500GB NVMe, 1TB SSD, 2TB HDD
Asus Prime B460M-A Mobo
If any interest, I'll post my experiences with this rig after launch.
Good luck to all!
