not certain though, anyone else?
First, you won't use higher than 4x AA in 1920 'cause it doesn't really make any apparent difference at this high resolution (assuming you are not displaying on a 10 feet projector) - rule of thumb says the lower the resolution the more AA you need.
Second no chance you'll take up 1GB - if I'm not mistaking baseline 1920x1200 8x SSAA means 72MB memory footprint; you have to combine with something else but I can't see any chance to hit 1GB with pp... you need an awful lot of textures etc to fill up that giant memory.
