Just purchased an AMD Phenom x 4 2.8 ghx, 640 gb hdd, 6 gigs ddr3 memory, and replaced the stock ATI 4350 with my own ATI 4850 512 mb. Power Supply is 600 watt OCZ. I have finally brought FSX to its' knees. How about that? Aerosoft Manhattan and San Francisco used to bring my AMD X 2 5600 to its crawling, stuttering knees. But not anymore, those 2 Aerosoft scenery packages don't stand a chance anymore. With FPS locked at 30, screen resolution set 1440 x 900 (desktop resolution is the same) this computer simply blows FSX out of the air. Take that Microsoft. One thing that is was wandering is, would a GTX 260 give me even better framerates?
