Rene and other knowledgeable folks,
In short, I'm wondering whether to upgrade my HTPC from a Sapphire 4550 (fanless) to a 4670 (probably this one)
in the near future or whether to wait for the 5670 or similar model early next year.
The 4550 won't go to waste; it will go upstairs to my desktop replacing a truly horrendous HD3450.
The only reason I would spend good money to replace an otherwise excellently-performing card is that I've apparently got the "judder bug"
when watching some live/recorded HD OTA content. I only see it on one channel, but that's CBS and I watch CSI and CSI-NY, and it bugs the crap out of me.
There are some reports that the 4670 reduces the severity of the problem. And other reports that it doesn't... and other reports that it's strictly a MS bug, and others that it's a video decoder issue...
Frankly I never saw the issue until I switched from Vista HP/Radeon3200HD to W7RC/HD4550. I swapped OS and video card at the same time otherwise no changes.
I understand the 4670 will have better SD rendering (Vector Adaptive) but I probably wouldn't notice the difference on my 1080i plasma.
Will the 5670 (or whatever number) have any seriously beneficial improvements over the 4670? Note that I'm not into the high end sound stuff... my receiver is strictly DTS/DD and I'm unlikely to change it within the horizon of interest here; I'm strictly interested in video handling on a single screen.
Frustration with this judder bug would lead me to spending the ~80 bucks for the fanless 4670 card if there's a reasonable chance it will cure the judder or give me any real benefits in quality of rendering either HD or SD content onto a 50" 1080i plasma (via HDMI). Or I can wait until the new crop of HTPC tailored cards is available...
Any comments appreciated.
