TSIMonster :
I really like that article and I am looking forward to the PureVideo and AVIVO one. I would love to build an HTPC soon and my x1950Pro is not avivo capable. Kudos on the article, it was a good read.
Not AVIVO capable? You have got to be kidding, as I know of *no* X1K-series card that lacks AVIVO support (while there are few X1K-series cards that support video-in, that has nothing to do with AVIVO, or even HD/video-out for that matter, as even the X1650 Pro in AGP supports that).
One thing I am doing nowadays, due to the PSU issues that still plague both the X1950-based cards (and the GeForce 76xx/78xx/79xx series, for that matter) is recommending last generation's midrange cards (ATI's X1650 Pro and XT, especially in AGP, in particular). Cards like the X1950 Pro and XT (and their nV counterparts) often require much beefier PSUs due to their current demands. The X1650 Pro (and X1650XT, especially in AGP trim) have the following to recommend it, especially if you are replacing an ATI R3xx/RV3xx-series card described in the review:
1. It requires no more power than the card it will replace. (Yes, they do require a four-pin PATA-style Molex; however, so did most of the R3xx/RV3xx cards). The X1650 Pro from ATI (typical of the breed), despite it's outsize 512 MB of onboard GDDR2, only requires a 350W PSU (same as the AIW 9700 Pro it replaced (which only had 128 MB of GDDR)).
2. No real compatibility woes. Again, compared to even X1950 Pro and the GeForce 7-series, there are far fewer hardware-compatibility issues between the X1650 Pro/XT and older motherboards (this is primarily due to the friendlier PSU requirements). On the *software* side, if you are replacing an ATI R3xx or later GPU, you don't even have driver replacement to concern you, as thanks to the unified driver architecture, it's simply a matter of re-detection. (This applies equally to Windows XP or Windows Vista.)
3. Value pricing. The X1650 Pro, in the 512 MB AGP configuration, has an SRP of $209, and is typically priced under $200, even retail. (I bought mine retail and paid $174, including tax.)
