Yes. 1G will draw a bit less power.

No difference in performance for hashing, some difference in performance on games, particularly at higher resolutions and higher AA.

Get the one that is cheaper! But make sure in either case to underclock your memory (VRAM) to 300 MHz or lower. This will make a noticeable difference in the cards overall power consumption (20-40W typically. for me it shaved off 40W!)
