Heyas Gorath Alpha
How did you measure the shader performances?

(The Official nVIDIA DAO Minimum was wrong and is way below here in the ranks, and various relatively recent cards, such as the HD 6800s, don't have the right benchmarks available yet for addition to the list)

What kind of Benchmarks are you talking about here?
I do own a HD 6850 and all of the Futuremark Products run on it, also the Unigine (Heaven) runs perfectly fine here.

I always look to Toms hardware for a benchmark on a game with similar
graphics to place the cards in the appropriate ranks, and neither those
nor the Radeon HD 6800s are included in those VGA charts yet.

Right I should have read the other posts, I can't find my Futuremark account settings right now or I would post/link my results here. But I can say:

The DA2 Demo runs with constant 60 FPS  on 1920x1080 (Vsync on, determined by fraps fps overlay)

GTA4:

Gorath needs a game very much like Dragon Age 2 to really be able to determine the order of the individual video card (or more accurately GPU) models in the ranking. Without scores for the HD 6800, 6900 and GTX 5xx families for a game like Mass Effect 2 or Dragon Age : Origins it is hard to make an accurate list. We will probably not see accurate benchmarks of the latest cards in such games anymore, so we will have to wait until Dragon Age 2 is released and it can be benchmarked.

Okay Gorath I did benchmark the Castle Cousland (Human Noble Origin) to give you a value to compare against DA:O chart over at tomshardware:

Frames, Time (ms), Min, Max, Avg
299420, 3227872, 0,1046, 92.761

Those values are measured under not optimal conditions for benchmarks eg. I had programs running in background (Firewall,Anti Virus, Firefox4 Beta) and my system is not overclocked in anyway.

My System:
AMD Phenom II X4 @ 3.2Ghz
8GB of Corsair RAM ddr3-1333@666Mhz (4x2gb dualchannel;unganged)
Sapphire HD6850 1GB of RAM (no crossfire)
Win7 SP1 64bit

Each time Toms Hardware drops whichever high-shader content games I choose for comparisons, I have to backtrack to the cards already ranked, and make new determinations how the various series fit together.  Where possible, I take an average for the very high end parts, putting all HD 6900s together, to keep the numbers of enties from being overwhelming. Combining still more like that is tempting, but for now, I'll stick with what I have. 

If you have other video cards besides your own that you can run the exact same test, with all the same background software running, on the same hardware, so you have a series of tests, repeated (you should re-run each three times to be assured than nothing odd affects a single result, and choose the mean value), that would be fantastic.  And that is what a formal benchmark amounts to, you know.

So, if my PC runs the demo ok, should it handle the full game as well?

Here's why I ask, I'm running a  Sony Vaio All-in-one unit with Windows 7, 2gb ram,  dual core 1.6 ghz processor and Nvidia 8400M 256mb graphics card.

Running on low settings and it had no lag troubles, and honestly looked fine to me. (I'm not particularly picky about the graphics anyway.)

I've already pre-purchased the game for ps3, but after testing the demo, may want to get the PC version for modding access in the future.

When your video device is that terrible, don't make any bets that the Demo is really a good predictor.

Hey Gorath... long time no see (my fault, been busy). Just to toss a wildcard into the mix, the HD4890s actually out perform any GeForce 2xx series GPU in the benchmarks I've seen, including the ones where they downclock the 4890 to compare it to cards like the 275.

Something to note: I have played through the demo on a laptop with a GeForce Go 7400. It will run with some lag on low settings, but it will run. The main thing holding me back on it at the moment is the processor: Mobile Core2Duo T2600, 1.83GHz.

Anyone have a T7600 floating around that I can relieve you of?

The nature of modern laptops being what it is, attempting to access the "inside" where the CPU is probably permanently soldered in place is far more likely to literally DESTROY both the mainboard itself and the chassis while trying to get them apart. 

Anyone reading that rosy description should wait for next Tuesday to check with others before trying the full game on anything as weak as that Mobile card (about the same as the desktop 7300 GS). 

Well, as a PC Support Tech, let me tell you that taking a processor out of a Dell Latitude D820 (which I'm currently running) is almost as easy as working on a desktop. The only difference is you're much more limited on choices with regards to what processors will actually run in the thing. I looked it up on Dell's own support page: the max this thing will handle is an Intel Mobile Core2Duo T7600, 2.33GHz.

Also, I've already removed and reinstalled the processor on this rig twice while cleaning the rest of the machine. The Latitudes' (and most other laptops I've come across over the last couple of years) processor is held in a neat little socket that, in order to remove the processor, once you've removed the heatsink, turn one flat head screw about 90 degrees and lift the processor right out.

Don't let Dell find out; unless you're certified through them on the machine, it voids the warranty to work on it yourself unless they know in advance (and they won't cover the work if you mess it up somehow).

Since in my opinion, this forum is beyond merely dead, I'm going to bail out and leave this one bumped to the top.

 i don't know what my problem is but i have 2 oc gtx 480's at 1.5gb each an i7 950 oc to 3.6ghz per core 6gb of ram. i turn the 3d off run dx11 with it on very high settings and 4x each for aa and af and the game is very very choppy and it has excessive screen tearing i have all the newest drivers and everything any clues? or is my cards not that good for that high graphics im also running the game at 1920*1080p
