I guess I can't do max with my 4850, huh? :( 

The second game I have come across that my PC may not be able to max, the first being Metro 2033... damn you Crysis 2 for lulling me into a false sense of security!

guys, recommended =/= max a lot of the time.

Would still be just shy though :(

Depends on the game and resolution, some studios will list reccomended as the specs needed to run at a specific resolution without AA etc others will include AA so everyone is different.

They have got to be over exaggerating. Generally games only require Radeon HD 3000 series graphics as their minimum.

well this game only requires a HD 2000 series for it's minimum it's the reccomended that is the problem, at least that suggests the game is scalable.

Wouldn't surprise me if you can run it on max and at top res and still get 60fps. Half the time I swear the recommended is just picked as what's nearly the best at the time and will likely give you >120fps at max settings and 1920x1080 res.

some AMD features detailed 

Square Enix have told us more about Deus Ex: Human Revolution’s PC specific features. The game will have full DirectX 11 support, and will work with AMD Eyefinity, which will let players hook up an incredible FIVE monitors to play the game in uber-widescreen. It will even run in 3D for those with compatible screens. The development team discuss the advantages of playing Human Revolution with 3D and Eyefinity set ups in a new video, embedded below.
 

Head of Nixxes, Jurjen Katsman describes a few of the improvements players with DX11 cards can look forward to. “We do use tessellation; this was one of the first features we started making use of with DX11. We mainly used it to improve character silhouettes, but also used it for some other objects in the world.

“In Deus Ex: Human Revolution you see characters up close a lot as you interact with them, like in dialogues. Using tessellation to improve their look really helps make the world and the characters more believable, which is important in a story-heavy game like Deus Ex: Human Revolution.”

The team say that they’ve significantly rewritten the engine to take advantage of the extra processing power of the PC. Even without DirectX 11, players with multiple core CPUs can expect increased frame rates. Eidos say that a dual core setup can be “up to a 70% increase” in speed on machines running on dual core rigs.

Eidos Montreal director of technology, Julien Bouvrais says “when it comes to DX11 or AMD-specific features we have developed, we wanted to make sure they were adding to the game and not just tacked on without real purpose.”

Deus Ex: Human Revolution is due out in August. For a closer look at the game, check out the firstexclusive PC screenshots, and have a read of our huge preview of the first ten hours.
