What is the use of a ati 6950 2gb

[vishalaestro]

will it accelerate the performance at 1080p game res with good frame rates..the monitor res is 1920x1080p..so will a 1gb card is enough or a 2gb card will be a future proof..and is a ati 6950 is better than gtx 570 or same as gtx 570

A 1GB card will be alright for 1080p but if you might crossfire and/or raise your resolution in the future then the 2GB would be a good idea.
The GTX 570 is a bit faster.
