Re: 6600 256MB vs. 6600GT 128MB
You could get the gigabyte one, even if it does not have a japanese manual, as you seem to read and write english quite fluently. Anyways, there is not too much of a difference in the card manufacturers. If the site has reviews, read the reviews on both the asus and gigabyte. The gigabyte looks like a good deal in this situation. Good luck with the upgrade!
