PureOverclock has posted a review on the Sapphire X1800 XT

The X1800 XT has significantly dropped in price over a very short period of time. Just a few months ago this card was priced at over 400, but now costs roughly =A3250~=A3270. This is quite a bit cheaper than the 7800 GTX. You can even grab an X1800 XT 256MB for around 230, too. I already know ofmany who are making the logical choice and are moving from 7800 GT's to X1800 XT's. Essentially what I'm saying is, the X1800XT is a very
interesting card right now, much more interesting than when it was launched.
