How accurate is this test for GPUs?
It seems to me that depending upon who does the test the results are very different even the the exact same GPU.

how is this test performed?

do you need a color meter to do this test, etc...... ?

I would like to use my GTX 460 so I can do a little gaming now and then.
I also own the GT430 and HD 6670 cards.

While not without value, you have to realize that the HQV test is to a somewhat large degree a marketing tool. In essence it was developed by Silicon Optix/Realta to show off the things their HQV video processors do well. For example a substantial portion of the score comes from handling odd cadences.

How accurate is it? Well when I played with the original DVD version, while it did rely on the user making determinations by eye, there were either objective marks to score from, or example of how things should be scored, so it's better than just subjective opinion.

See what an anamorphoscopic lens can do, see movies the way they were meant to be seen

my bad, looks like it's no longer for sale to the general public.

I will just use my GTX 460 and my GT430 will be my backup for now.
they use about the same amount of power when in HTPC use.

Nowadays I rarely use HQV Benchmark, except for a few patterns (BTW HQV -> IDT -> Qualcomm; I bought v1 from HQV, v2 from IDT). I often find Spears & Munsil HD Benchmark is more useful.

thank you for the useful information....

do you like the AMD GPU's over the NVidia GPU's?

I ask this because I can't decide if I should use my GT430/GTX460 or my HD 6670.

I have the HDhomerun Prime CC Tuner with Comcast.
and may rip some blu-rays to my HTPC....
and stream Netflix now and then....

Several criteria:

Deinterlacing (video mode, film mode): Both are good
Chroma upscaling: Both are good or AMD is better
Image upscalng: Both are poor.
Black and white output range: AMD supports both full-range and limited-range, NVIDIA supports only limited-range (unless you hack the registry).
Refresh rate: AMD is near perfect, NVIDIA requires creating custom refresh rates.
Decoder: Both are equivalent (NVIDIA supports decoding 4K H.264 up to 30fps)

HQV Benchmark includes several other post-processing tests (denoise, edge sharpening, dynamic contrast enhancement etc.), I say both are good, but I would never turn them on.

Overall I prefer AMD.

thanks for your help, from all my research in the past I also came to the conclusion that AMD was the way to go.

that's why I picked up the HD 6670 2GB DDR3 Video Card.
