I reckon it's gonna look pretty good - see quill's system for example, not a super computer by any means. I'm on a 6700k and 980ti (so 4 years old at least, but runs anything decently) but with terrible internet which might be a kicker. I think it'll be mindblowing even not set to max on these given FSX fully modded looks good even now, but has a nasty frame hit sometimes. Either way, I can see myself shelling out for the full version after about 2 hours in the basic one. Particularly looking forward to the third party stuff. I wouldn't touch FSX now without Traffic Global and FSXWX etc.
It's a shame Manchester isn't one of the premium airports, but I'm sure someone will resolve that before long.
