from experience, you'd want at least 4 GB of ram, Solid-State Drive, a highly overclocked quad-core (take a look at the Core i5 2500K. that CPU at 4.5 GHz should be beast for FSX).http://www.simforums.com/forums/topic29041_page1.html
^that is immensely helpful. I play this game also and there is no way you can max it out at >40 fps wih this gen or next gen of hardware. we'll have to wait for 22nm. but this game benefits from fast quad-core and ram
notes: with my sig rig right now, i can pull 28fps (limited with built-in fps limiter) in all areas with all sliders in the game cranked up according to the forum post above except for densely populated cities. CPU usage minimum is 60% and maximum is 100%; usage peaks at regular interval when game is loading texture on the fly. ram usage peaks regularly in the 90% with only 3 GB. CPU: 3.5 GHz. RAM: 1600 MHz cas 8.
again, investing in the lastest core i5 2500K will be worth it if ur serious about this game.Edited by james8 - 5/24/11 at 5:22pm
