Hi i bought couple of VGA cards as mentioned on the compatibility list, like HD4650, 8600gt as mentioned, but i am having some trouble on 8600gt on windows 7, my arcade monitor is as mentioned earlier 31khz one and can display 640x480, it works fine with hd4650 with soft15khz but when i change the card to 8600 gt the screen is like a junk and flickering too much, cant see any thing, it happens when i install the driver for it. without driver it is fine i dont know what to do..
help is needed as i am really new to arcade machines by the way i have naomi universal cab if it helps.
