Besides I buy what I think is best for me. I still own 2 radeon HD 5870s.
The point of tessellation isn't to increase performance.

Tessellation allows for much higher poly models in games without a large impact on framerate. It basically allows for a continuous LOD on any mesh. This kind of LOD has been around for a long time, but usually only on terrain, whereas polygon soup meshes that generally makeup most of what you see in a game would just have a few levels of LOD. When you have LOD levels players will often notice that, where you're walking through a level in-game and you suddenly see a model become much more detailed in an instant. Developers did their best to setup the LOD levels to hide this so it isn't always noticeable, but even the best games still have it. Once you switch to tessellation you have a continuous LOD, which makes the removal or addition of polygons virtually unnoticeable.

Long story short: Adding tessellation to a game just allows for higher poly models and a smooth LOD without the huge performance impact that you would get without tessellation. What tessellation won't do is increase performance on any game that doesn't utilize it properly.

Umm, your tessellation performance would plummet in a game though. AMD only has a dedicated unit for this stuff, where as your card is using it's "Polymorph Engine" 100% for tessellation. In a game you could never get that kind of performance.

They probably need to rerun the test anyways. I get 727 in the Insane test at the same settings and I'm only running at 950 core right now and that's with the CCC tessellation setting at "Program Default".

You are correct.But Ati's goal is to increase performance during tessellation. But as far as Nvidia gpu's Tessellation it reduces performance coz it uses its cuda shaders. Where ati always has better performance when it comes in-game tessellation due to its dedicated unit. low quality tessellation like Aliens vs predators will give huge boost to ATi owners but sadly it can't handle very high no.of polys like this test this in turn developers are forced to follow to implement low quality tessellation to satisfy ati customers

Not to sound rude but I know that. Why exactly did you think that I did not know what tessellation does? The 'gains' part I guess? Well I didn't mean fps gains, so I was not talking about performance

sorry if the post was confusing. I meant that I have not seen any significant visual improvements because of tessellation in games.

Great news, i'll take any gain in fps anywhere. As it turns out metro 2033 at 5760x1080 makes my computer cry with all of the settings are cranked, Not sure if metro uses tes or not, but hey gains are gains, I see crossfire in my future...

I wish they'd stop worrying about tessellation for about 15 minutes and just stop the idle clock drops when you overclock the card. I am sick of this issue and its been around since the HD4XXX series. It wouldn't be so bad if I didn't know they are PURPOSELY doing it. It causes dual or triple monitors to flicker and flash something horible.

You can fix this yourself, search on how to fix it. You overclock the card, you fix it.
