Graphic Card question?

It seems that they are the same. I would go for the 1 GB card if I were you though. That way, you can turn up the texture resolutions with minimal frame rate loss.

better you buy 4850 ...it much better..if you buy that graphic you will not really satisfiy with the graphic

Hey, I got the same HIS hd 4670 its overclocked to 780/1000 but I overclocked it further to 831/1200 and it seems very stable and was able to get crysis at an average of 33fps on just high settings which isn't really bad for a low/mid end card. Save yourself the money and get the 512mb but if you wanted to spend on the 1gig might as well get something higher such as the 9600gt/9800gt
