Benchmark Results: Left 4 Dead
This one has never been particularly GPU-limited, so it’s hardly a surprise that the Radeon HD 4850, Radeon HD 4770, Radeon HD 4830, and GeForce GTS 250 perform at least somewhat similarly. Any of those four cards will serve up a satisfying experience if you keep anti-aliasing and anisotropic filtering turned off.
The Radeon HD 4850 and GeForce GTS 250 hang in a tight grouping as additional eye candy is applied. The Radeon HD 4770 falls back a little bit, but still manages to deliver playable frame rates through 1920x1200. The only card incapable of keeping up is the Radeon HD 4670 with 512 MB of GDDR4 memory.

What a shame they could not shave few watts off power consumtion to use it without PCIe power connector. Or at least made the card to work without it and PCIe power connection as optional when You overclock. Hopefully some of the board partners will do that.
Pretty decent review.
Question on Test Setup: what are the GPU/GDDR clocks? Reference?
This just goes to show that AMD is more than CPU's. Looks like you get a lot of card for your money here, and it's not a hand-me-down technology, either; it's cutting-edge.
Here is a rivetuner edit that works. Just change RV770 = 9440h-9443h,944Ch into RV770 = 9440h-9443h,944Ch,94B3h in Rivatuner.cfg
I got mine to 888/1000
