Looks promising; I hope the features of the game live up to the high-performance requirements. I figure my rig falls somewhere between recommended and high-performance; due to Cypress' tessellation and compute limitations such features will probably cause the 5870 to choke where a 7870 will not.
One detail that seems out of place is an FX 4150 being the AMD CPU recommended for high performance. That's only two Bulldozer modules (four cores/threads), and not even the highest clocked version at that. An i5-2500k would blow it away, let alone the high performance recommended 2600k. Other than that, the minimum and recommended requirements only name dual core CPUs. Makes me wonder just how optimized this game will be for multiple threads.
This is an EA published game...might not come to steam but Origin instead.
Well, it depends. EA games not being on Steam is not entirely EA's decision. Essentially it comes down to how updates and DLC are delivered. Valve wants a piece of the DLC pie and changed their policy for newer games, and EA doesn't want to share. Thus, recently developed games that EA provides DLC for directly, like Dragon Age II or Mass Effect 3, aren't on Steam. Crysis 2 used to be on Steam, but got taken down because EA would not comply with Steam's new terms of service. However, EA has since then released Crysis 2 Maximum Edition, which included all of Crysis 2's DLC on the disc/single download. Since EA was not going to release any more DLC for Crysis 2, Valve allowed it to be released onto Steam. You can go on Steam right now and purchase it.
So essentially, Crysis 3 will not be on Steam initially. When EA finishes releasing DLC for Crysis 3 and if it releases a similar edition of the game which compiles the DLC all onto one disc or download, it will probably be released on Steam. But it will probably take a while for that to happen, if it happens at all.
