#2 There are no games that require even 128Mb of video memory (to my knowledge. and if there is, the visuals must be ****ing stunning) so why have 256MB when no game requires anything close to that?
The highest video memory requirement I have ever seen is 64MB.
About the only thing you would need 256MB of video memory for would be if you are editing gigabytes upon gigabytes of video files.
