AMD's new Radeon HD 6670 offers decent 3D performance for resolutions up to, including, 1280x1024. If you are willing to sacrifice some details settings or live without anti-aliasing then 1680x1050 will be possible too in many games. Even though AMD's EyeFinity support promises a better gaming experience, for this segment I think it's usefullness shows in non-3D desktop applications. Being able to use multiple monitors can be beneficial to productivity, the added screen estate really helps. For an office PC the HD 6670's low power consumption is also useful since it helps with the power bill, which can make a difference when deploying a lot of systems. For gaming we saw outstanding performance per watt scores, in 1024x768 no other card is even close to the HD 6670.
HD 6670 is sitting in a tight spot price/performance wise. For just $10 more you can get a HD 5750 and $20 more gets you a HD 5770, both of which offer more performance. For the case of HD 5770, which leads our performance per Dollar chart, $20 more gets you a 46% performance increase! If you want a cheap, sub $100 gamer card then a used GTS 250 will give you more bang for the money - if you can live without DirectX 11. In this performance segment DirectX 11 support really doesn't offer much of a benefit, instead of improving performance by using the new API, all developers use it to add eye candy which reduces performance even more.
A realistic market price for the HD 6670 would be somewhere around the $80 mark where the card is sufficiently far away from the more powerful $100+ cards and $80 last generation cards would quickly lose out to a $80 HD 6670 because HD 6670 adds more features and better resale value at the same price.
