That doesn't mean nearly anything when balanced with how much performance increase you get with Kepler. If you're looking at HWCompare then you're looking at the wrong place. Look at some real benchmarks. The 670 performs almost at 680 level! the 670 is MUCH MUCH faster. Everyone is way too worried about how much VRAM something has these days. If you have only one monitor then 2GB is PLENTY and for most things 1GB is GREAT!
