I’ve been planning to build a new PC for many months now. Unfortunately, final decision still hasn’t been made due to rumors that this and that newer and better hardware are coming in a few months — I know we never can catch up with the latest technology.
Anyway, the following guide from Jetline Systems that I came across is a good quick reference. For example, I originally put Nvidia GTX 690 on my purchase list for the new PC since I am planning to expand my system into a 3-monitor setup. The guide reminds me again that Nvidia GTX 690 and other dual GPU cards might significantly impact FSX performance. Even though the info isn’t detailed and comprehensive, I am now putting the card on hold and searching for more information.
If you are planning an upgrade for your computer like me, worth taking a look of this guide to get some references of what hardware we should focus on for a better FSX system. We could also gain some hardware information that the company selects to build their PCs for FSX customers.
