The 9800Gtx has been available in retail stores in Australia for a week.

It's about $375 in a cheap shop - thats a lot less than 200 UK pounds. Performance is better than the 8800GTX, but not a lot better. It's 512mb memory is blamed for it not being quicker in some games.

Word is that the replacement to the 9800GTX, due by Xmas, is a LOT quicker.

As benchmarked by hexus it does not out perform the 8800GTX it is actually worse in some cases which is scary.

I'd wait til nvidia get 55nm GPU's out. It might help quieten the loud fans.
