AnandTech has a mid-range summer 2006 GPU roundup:
The current landscape of $200 - $300 graphics cards is quite well suited to the enthusiast who wants good performance and quality for a reasonable amount of money. As such, we will be taking a look at this market segment as it stands. This really does seem to be the sweet spot in terms of bang for the buck right now. We won't be able to run Oblivion with all the options enabled, but all the games we test will look good and play well. We won't be surprised to see a few more entries into this market before the end of the year, but we are certainly over due for a good hard look at anything but the high end.
