Would I be able to run Flight Sim X on the very highest settings with the following rig; 2600K 16GB 570 GTX F3 OCZ 3 Thx...
A lot depends on what resolution you're running it mate. I know it was very CPU hungry - the more threads the better - and it has been patched a couple of times to improve performance so, providing you're not running a mahooosive monitor you should be alright. Check out the FlightSim forums clicky - they ought to have a bit more knowledge.
Yes, but FSX can be maxed with older hardware too. You can always expect to go as low as 10-15fps no matter what hardware you have, but the average fps will be considerably higher with the system you outlined. I had a quick look at the flightsim forums and people who have the 2600K are reporting as low as 10fps with the settings maxed out, but that can be improved by tweaking the config file. FWIW I run it with the system in my sig @ 1920x1200 and it runs fast, but go to a busy airport or city and the fps will drop considerably.
