I recently upgraded from a three 4 x 3 monitor setup using an analog TH2G to the digital TH2G and three 16 x 9 monitors. About two years ago I upgraded computer to a AMD Phenom II X6 1090T with 4GB RAM but retained an older ATI 4870 x 512K video card. Knowing that FSX is not terrible dependant on video card, would there be any advantage to upgrading video card to something newer with more memory?
