Nvidia 6600LE?

[Wheemer]

Will an Nvidia 6600LE be enough to support HD playback? Would this be a good choice for Sage?

Seems as good as a normal 6600. However, it is missing 1080i deinterlacing.

Thanks MlbDude!

Am I missing where it says on that page that 1080i is not supported?

Also, can someone explain what "Spatial-Temporal De-Interlacing" is exactly?

"Spatial-Temporal De-Interlacing" is the 1080i deinterlacing. Technically without it you can still deinterlace 1080i, howerver, it will only be with a BOB type method.

Here is a good quote from an Anandtech article:

"The process of taking interlaced content and displaying it in a non-interlaced form is often referred to as de-interlacing (for obvious reasons). There are two basic methods of de-interlacing, commonly known as "bob" and "weave."

Bob de-interlacing is more technically referred to as linear interpolation and it simply fills in the missing lines of resolution by interpolating between the resolution lines that are available. This interpolation form of de-interlacing is particularly useful if there are a lot of solid colors on the screen and if the decoder screws up and decides to combine two fields from different frames.

Weave de-interlacing, as the name implies, simply combines alternating lines of resolution from two separate interlaced fields. Using either method individually is generally not the best way of doing things, but thanks to the decent amount of power in today's PCs more sophisticated algorithms can be implemented to dynamically switch between bob and weave on a per pixel basis within a frame (usually referred to as adaptive per pixel de-interlacing).

NVIDIA's PureVideo supposedly takes adaptive per pixel de-interlacing one step further with what they call Spatial-Temporal de-interlacing. The idea here is that normal per pixel adaptive de-interlacing uses data from fields within a single frame to essentially fill in the blanks. NVIDIA's Spatial-Temporal de-interlacing can use data from fields in other frames to improve de-interlacing quality. We'll have to see if this ends up improving quality or not in our tests later in the article. "

Cool... thanks a lot, that makes it all clear now.

I don't want to limit my options for the future, but I only have an SD tv for now. I'm feeding it through svideo. I'm looking to improve the image quality from my current FX 5500.

Do you think I'll notice a worthy difference? Are the svideo outs different between the two cards?

Thanks!!

For SD you will probably not notice a difference from what you are at now. There are some nice features in the 6x series for advanced deinterlacing but they are generally for items that are hard to deinterlace and get used infrequently.

For HD the difference may be more apparent. I used a regular 6600 for a long time with full HD. Switched to a 6600GT when the new drivers came out for full HD deinterlacing. I honestly did not notice a big difference in PQ. Panning did seem a bit less juddery but overall I was very happy with the 6600 due to it being quieter and giving off less heat.
