    I think the 550ti is the most useless release this year and yes even though the 6790 card draws more power than i would like its still miles ahead of the 550 ti. As for the gtx460 768 i think it would be stupid to take it off the market its nvidia's new 8800gt and only competition for amd 6790.

    The best part of 6790 appears to be the bitchin' CF scaling, if nothing else. Depending on where prices end up, it still would be hard to recommend when a few dollars more can get you the 6850.

    Should be a bit cheaper imo.

    I would hope that prices end up around $139 or so, without rebates. Still the 5770 and 460s are the value kings, so I'm glad to see AMD not over pricing them. nVidia could take a lesson.

    rohitbaranWow. Great card for the price, considering what nVidia has for the same segement.Nvidia no longer has anything in this segment. Well, maybe the GTX460 768, but on average it's still priced above $150. The GTX550Ti underwent an expected below MSRP price drop soon after launch, and the average price is now around $130, probably where it should've been to start.

The GTX560 is set to replace the GTX460 768 and compete directly against the HD6790 at the $150 price point.

    Nvidia fail at the mid range segment. the only good card they have released recently was the 460. the 450, 550, failed hard. this card will be good if the companies can lower the the power usage. good job ati

    On the final graph, why is the 6790 listed below the 460? According to the graph it should be above it.
