"AMD is really pushing its advantage while the iron is hot and
continues to bring the Evergreen GPU technology to more price segments and
consumers' budgets. The Radeon HD 5770 and HD 5750 bring DirectX 11 gaming
to a completely new market (even though there is only a single title
available today) while NVIDIA is still months from offering any DX11-ready
hardware. The performance and power efficiency of the Radeon 5800 and 5700
cards also continues to impress; a user could run a pair of HD 5770s in
CrossFire under the same thermal envelope as a single GeForce GTX 260+!"
