Sapphire Radeon HD 4670 512MB video card review
Elite Bastards posted a review on the Sapphire Radeon HD 4670 512MB video card

Compared to the RV770 core and its 956 million transistors on a 55 nanometre manufacturing node, RV730 is made up of 514 million transistors (also manufactured on a 55 nanometre process) and squeezed into a 146mm squared die. RV730 carries all of the same basic functionality as its big brother, from Shader Model 4.1 and DirectX 10.1 support through to the second generation UVD engine and hardware tessellation unit.

Into that transistor count, AMD have managed to pack the same basic amount of processing power as their previous generation high-end core (RV670), giving the Radeon HD 4670 a total of 320 Stream Processors to play with, which are arranged as eight SIMD cores, each of which sports forty Stream Processors (against ten cores with eighty Stream Processors in RV770).

Samsung LN-T4681F 46 Inch 1080P LED Backlit LCD TV Review
Tweaknews.net posted Samsung LN-T4681F 46 Inch 1080P LED Backlit LCD TV Review

At first I thought there is no way that LED technology can make up for the cost difference when compared to a standard panel lit LCD TV. Boy did the LN-T4681F take those thoughts, write them down on a sheet and paper and shred them to confetti right before my eyes.
