Sorry for the mistake of English. I'm from Brazil, I'm new here and use GoogleTranslate.I want to thank everyone on this site, it is of great importance, where I'm taking all the doubts in choosing the computer for FSX.flight1986, I'm already two weeks analyzing everything about computers, I'm in the same boat as you. Which GPU to choose?In my case I am building a i7-2600k, Corsair HX 850, 500GB HD SATA3, P8Z68Deluxe/Gen3, 4GB Kingston Ram, ATX Chassis BX1 Sentey-4285, Hydro CoolerH60.In a matter of choice, I'm going to have the best, but if money is tight, I'm taking theram and GPU cheaper because I still have to buy the Saitek controllers.Here on the site, I saw a lot and also the recommendation that staff uses GTX 580and GTX 570. About the GTX 460, I saw very little comment, but I'm between 520GT or AMD for that I am still thinking. But six months from now I will buy the GTX 580.Any doubt I am to help.
