Radeon 9800 or Nvida 6600?

[GbrNole]

the last time i delved into ati land was when i had my 9500 pro and i could get 1080i working over dvi out of that (using powerstrip) but got massive audio stuttering although the video was pretty smooth - i sold that card to a friend but i have since learnt that the audio stuttering was a conflict between that card and the onboard realtek spdif audio i was using.

so with that in mind i'm on the fence between off loading my fx5900xt (man that thing is quiet for a stock card) and picking up a 9550 extreme/9600 pro or maybe a used 9700 or 9800 (either one of those would have to be 256-bit to consider them though)

the whole 6600gt thing is really annoying me though because it's a great card but all i keep seeing is people bitching that it's using high cpu for wmv-hd and even dvd playback.

maybe those doing the bitching just don't have dxva enabled - not that dxva would help wmv-hd.

In this thread powedercarrot says:

my only problem now is that I can't get 1080i through my DVI output to DVI in on the TV. It works perfectly with component, but if I try the same settings with DVI (or try adjusting the underscan percentages in the nvidia control software) the screen just goes blank.

He later goes on to say:

I've tried 67.03 and it still does it. 70.90 worked great, though.

Regarding this:

I have never gotten 1080i to work long on my ATI though out of DVI. What info do you have on that?

I have a plain 9600 fanless card, and have it working with 1080i using Cat 4.8. It's overscanned, but it doesn't bother me since I just adjust the SageTV interface to fit within my screen.

I just followed these instructions.

To get 1080i with DVI I just go to to Properties > Advanced > FPD > Troubleshoot. From there I just check both the "force 720" and "force 1080" checkboxes.

The annoying thing is that after a reboot I have to do the samething again for it to work. Not too bad since I hardly ever reboot or shutdown my HTPC.

I get that far with the ATI DVI at 1080i but then when I run some apps, MCE and ZP, it goes haywire and out of zync.

That sucks! Running Sage, BTV, and Theatertek has been fine with it for me.
