Best PQ gfx card on the market today?

I'm about to buy a completely new HTPC and I have been reading for hours and hours about gfx cards in here but not really any about picture quality comparison.


I remember in the old days how Cliff used to use all kinds of tech. equipment to measure the different boards with the Mpact2 as a winner

I would like to know what card is THE card to get today! Gforce 5700? 6600? 6800? Radeon with MP mod?


I don't care about games, just VGA picture quality to my Marquee Ultra.

I don't care about if it's AGP or PCIe, just want the best PQ.


Thanks in advance.
