Re: All Graphics Cards related queries here.
Please do not take this as me harping about the new 5xxx series and/or ATI. I am clearly stating this from a technical point of view with reference to the above and current line up of GPUs.
There is quite a bit difference when using Dx11. It offers stuff like Tessellation, multi threading, Dynamic Shader, Shader Model 5.0 to name a few.
Here is a good link to an article. If you are from a programing background you would understand the new powerful features and capabilities which are available via the enhanced API. This will take make game programing to a higher level, and greater advanced features will be shown. Game programmers will quickly adopt to this new technology, and we as end users will see more game on this codepath.
I personally feel Tessellation will 'change the way' 3D will appear on our screens. Basically as of now 3D is rendered via polygons. Shapes are drawn inside wireframes, and pieced together using multiple polygons. And this wireframe is drawn over and over really quickly to shown movement. What Tessellation offers is that: these polygons can be further subdivided automatically into smaller and more detailed shapes, and each of these shapes can be 'controlled' for color, geometry. It gives power for greater detail and image enhancement, with far far greater control. All ATI cards which are >= 4xxx series have this tessellation engine in-built.
To see a classic example, go to this link, and click on the wireframe buttons for the dragon and house. You will see the amount of polygon counts increasing by a massive amount to render the same image.
You could download the Unigine demo from the same link above, and run it. If you do not have Windows 7 and a GPU > HD4xxx, then run the demo in Dx9, and press F9 to see the wireframes. Its phenomenal.
Regarding the change from a HD4850 as of now. Depends, if you want to see all of the above, and have the cash... go for it. Simple as that. I doubt prices are really going to get that low. nVidia has not even announced its paper release. It is confirmed that their line is facing issues at TSMC. We could argue that getting a 5xxx card, we miss out on PhysX. But a lot of it can be (not all) processed by the CPU. I ran Scorpion Disfigured and saw PhysX affects. Not the best, but they were there. But imagine with a Tessellation capable card (and of course it will be powerful too), what the gaming experience will be.
Choose and be a winner...else wait and watch. (Like most of us are).

@Tkin: Excellent write up.....!
I guess both Tkin and I were writing our essays at the same time, I did not even see his, doubt he saw mine. But now both are there.
