I've been away from FSX for a number of years. I'm going to get back to it now. My old system that I built when I was running fsx is an i7 950 with 6 GB of RAM and a GTX 470 card. I'm not going to do a new build right now but I would like to do a small upgrade perhaps on the RAM. My Asus board has 6 memory slots and will accept up to 24 GB of RAM. Should I increase the RAM? Get a new SSD dedicated to fsx? A new video card? Upgrade to windows 10? All of the above? After the upgrade I will do a clean install of windows, fsx, and any of my addons that I plan to run.
