Aside: One thing I did with both NV cards that did not work well with ati chip is to enable the OpenGL for verticle sync option. I haven't tried without it so it may be important (or not).

However, for ATI, it certainly applies. With compiz the opengl overlay on my x700 has massive screen flicker.

Like deanjo I put a cheap fanless NV card in (7200GS I think) and presto, great video quality on the mythfe.
So right now I'm pretty annoyed at the suggestion that ATI/AMD video hardware is appropriate for linux HTPC use. I think it is totaly fair and understandable that ATI has the vsync feature low on their prority list (or they are hoping the OSS driver will implement it or whatever); I just think that linux information on the ATI hardware should be pretty clear that there are several applications it won't work well for.

So my experience is that both makers have decent hardware for HTPC uses, or at least NV44 and R580 gear works nicely. The R580 has the edge in image quality outputting to a CRT TV while the NV44 card is really more appropriate for an HTPC due to it being fanless and small (R580s are large, rather warm cards.)

does anybody know, if the 4670 is supported by OpenSolaris ?

So far I would be happy just with 2D, better than nothing ;-)
I searched myself a little bit on phoronix, it seems like there is a RadeonHD Port for Solaris:
Phoronix, Linux Hardware Reviews, Linux hardware benchmarks, Linux server benchmarks, Linux benchmarking, Desktop Linux, Linux performance, Open Source graphics, Linux How To, Ubuntu benchmarks, Ubuntu hardware, Phoronix Test Suite
But RadeonHD itself has some issues with the 4670:
Phoronix, Linux Hardware Reviews, Linux hardware benchmarks, Linux server benchmarks, Linux benchmarking, Desktop Linux, Linux performance, Open Source graphics, Linux How To, Ubuntu benchmarks, Ubuntu hardware, Phoronix Test Suite
Well I'll wait and see what kind of RadeonHD will be included in the 2008.11 OpenSolaris release ...
thx for the answer

There is only one graphics engine in the HD2xxx, 3xxx and 4xxx parts -- a unified shader 3D block -- so 2D, video and 3D acceleration all more or less come together. That is why you aren't seeing 2D, then video, then 3D spread out over time like we did with previous chip generations.Test signature

I guess I'll go with the 4670 and wait for the RadeonHD Team to fix the current problems. To me it seems not to be overcomplicated. According to the article posted above it works, just the DVI Output does not function.
