The message title says it all. I'm looking for a graphics card that will give me the best performance for FSX, while staying within my budget of around $300. I'm running an AMD Phenom 3.0mhz, with 16gb RAM, 1tb HHD and two, Sapphire Radeon 6770 graphics cards. Even with this configuration, I am unable to fully utilize all the FSX features, i.e., ground traffic, ships, aircraft, ground graphics, etc. Any ideas as to which graphics card would be best for me?
