Thanks a lot for the advice, I will defenitly look into the different things you mention.
In all the years I have had a PC I have never (and never will) overclocked it, so that’s not an option.
I guess my first choice will be to go hunting for a new (used?) GPU, as I gather that my MB and PSU, can handle it.
Someone wrote that I also can use DDR4 RAm sticks instead of my current DDR3, just to confirm, is that correct?
I did consider a Xbox X, but as you also mentions, it wouldn’t allow me to use third party addons (like the FBW Airbus) so that’s out of the question, but yes, that would have been the cheapest way to “update”.
