So I went ahead and ordered FS One with Mode 2 controller. From my experience with sims generally I should be able to tweak the performance to a good level until I get more ram and better GPU.

I wanted to mention here also that reading about RC sims in this forum has been extremely useful to me. Special thanks go to Cybert99 for the comparison chart.

Another very useful insight I got from the posts here is that it's good to get the sim WITH the sim's own TX, because you ideally don't want to be using your field-TX every time. That shouldn't be used like a joystick and with a dedicated sim-TX you can care freely practice as much as you need. And you can still connect your real TX when needed.

Thanks to all who post on this forum. I learned a lot from the posts and I think I made a good choice for RC sim'ing.

Cheers
