Crysis
The famous Crysis, at 1680x1050, points up the closeness of the various cards performance-wise, if you exclude the GeForce GTX 200 and Radeon HD 3870. Under those circumstances, the GTX + had the performance edge it needed (9%) to move ahead of the 4850. On the other hand, enabling antialiasing seemed to favor the Radeons once again, with the 4850 showing performance that was 39% better than the 9800 GTX +. With the other settings, only at 1920x1200 was the game playable, provided we kept expectations low, and only in certain lightweight scenes. At that resolution, the two cards posted the same performance – 16% below that of the GTX 260.

$450 in Best Buy for a GTX 260.
And the 4850 is pretty close to the 280.
Ouu the 4870 is going to give Nvidia a run for there money
for the first time in a while.
P.S. +1000 -> 2222
MaxSmoothedFrameRate=62 in the Engine.GameEngine section
"it was unavailable due to the sloppy handling of this launch"
Seriously? AMD can't control if their retail partners screwed the pooch on the release date, because they were so anxious to get people this great product. They made sure the product was readily available well before the launch date.
They should be praised for not having a paper launch, not told that it was a sloppy launch, very poor form saying that.
Hell i went to best buy and bought 2 4850's on sunday, when the cards weren't even supposed to be available yet, the guy told me "they have been in stock for over a month in the back, they aren't supposed to be available yet but i can get two for you." Were the AMD police supposed to come and smack best buy on it's hand and keep me from giving them profits?
Sorry if i'm ranting, just put the blame where it belongs.

In french, but the graphs talk by themselves. Ho, and if you want a short translation = impressive and incredibly more efficient than Nvidia (if you compare the size of the GPU, yes it's A LOT more efficient)
The next couple of months are going to be interesting.
The review uses OLD DRIVERS for the ATI cards & gets worse from there.
The drivers used for Nvidia's cards> ForceWare 177.34 beta. Release Date: June 15, 2008
The drivers used for HD4850> Catalyst 8.22 Release Date: July 17, 2006!!!
Malovane > Unfortunately we needed to review Crysis in 25*16 in order to be able to calculate the average framerates of each board with each resolution, including the 25*16 that is playable on most games. And to show that no board can currently run Crysis in 25*16.
"If you attribute your 4850 test crashing due to your motherboard.. why throw in results of 0 across the board for the 4850?" > No, I attribute the crashing to the Asus Radeon 4850 TOP that we reviewed.
