Which Nvidia 6xxx card to get?

I'm considering building a client for my den (will be SD content scaled to 1080i) and was wondering which video card to get. I want a Nvidia 6xxx card, but I'm not sure which model to go for.

I'm currently running a 6600GT using VMR9 at 720p. I only have SD and don't forsee myself getting HD anytime in the near future. From what I understand the vanilla 6600's have all the same features as the GT except for HD Spatial-Temporal De-Interlacing. Since I'm viewing SD upscaled to HD resolutions I assume the GT isn't providing any benefits over a regular 6600. Is this correct?

Also how does a 6200 compare to the 6600GT as far as upscaled SDTV goes?

Basically I'm looking for the cheapest video card that will still provide comparable quality to the 6600GT in my particular setup.

For SD, the 6600 and 6600GT should be equivalent. As for 6200 vs 6600, the 6200 is missing the film mode/inverse telecine/bad edit correction, which IMO, is something worth having, given a lot of TV content is mangled film source.

Stanger, are you 'positive' that NONE of the 6200's do "film mode/inverse telecine/bad edit correction"?

I've seen all the matrix(ies) at Nvidia, yet none of them specify the newest 6200A, which uses the NV44a chipset. Note that this chipset is specifically for the AGP bus. It is the newest chipset for the 6200 series.

I know that the PCIe flavors of the 6200 are crippled in this regard, especially the TC models. (they use the NV43 chipset)

Any thoughts?

The bottom line is that the 6200 does not have the memory bandwidth to process HD 720p or 1080i feeds whether they are from OTA sources or recorded sources, in VMR 9. I've had one, I tried it, the picture is great but it stutters/drops frames like crazy because the 6200 cannot keep up, in VMR 9.

It does fine in Overlay, but the difference in picture quality between Overlay and VMR 9 is very noticeable, even on my modest 30" widescreen HDTV.

My question wasn't about HD content, but about SD content that is being upscaled to 1080i. Did you have the same problems with SD content? Also there are different versions of the 6200 some have a 64 bit memory interface and others 128 bit. Was your's the 128 bit? Were you running in FSE, because my 6600GT chokes on SD content at 1080i when using VMR9 without FSE enabled.

Of course if the 6200a doesn't have film mode/inverse telecine/bad edit correction then it's out of the question anyway.

Thanks, looks like the vanilla 6600 might be the best route for me to go.

I know what you know, just what the matricies tell me (as far as the 6200 goes. What I do know is that, as you say the AGP ones are based on the NV44a, which would seem to be based off the PCIe 6200 (NV44) core. Vs the 6600 core, NV43. I'd be surprised if the NV44a had different features than the NV44.

SD TV stuttered as well with the MSI 128MB 128-bit 6200 that I own. I use FSE whenever I use an nV card.
