I just installed Vista Ultimate 64 bit on a new pc I just built. System properties shows 64-bit Operating system. But when I go to display settings the tab where it says "color" says Highest(32 bit). What does that mean? Does one have any thing to do with the other? My PC Specs:MoBo: Asus M3A32-MVP Deluxe/WiFi-AP, a MSI RX3870-T2D512E OCgraphics card. 2gig memory And a AMD Phenom X4 9600.
