a great in-depth artical, as I've come to expect from this site, small as it may be. A good artical.
Before the launch of the RV 570 and the R580+, the lineup for ATI consisted of the X1800GTO, the X1900GT, and the X1900XT. The X1900GT was often beatin by the All in wonder card, which was going for cheaper, and as such did not make any big waves in the graphics market. The X1900GT has effectivly been scrapped, since then.
It seems to me, around the time the X1900GT was deemed a bummer, X1900XT 256mb cards started popping up, the first one I saw was from Sapphire.
A few months Later, ATi released the R580+, and the RV570. The RV570 closed the gap between the X1600 and the X1900, with the introduction of the X1650 XT and the X1950 PRO, the X1650XT acting as somewhat of a refreash to the now deemed obsolete X1800GTO. ATIs lineup now seemed nearly flawless, starting from top to bottem X1950XTX, X1950XT, X1950PRO, X1650XT, X1650Pro and so on.
The thing is, X1900s can still be found, and the X1900XT 256MB maintained its
$200-$250 price tag the whole time. Now, the X1900XT 256MB stands cheaper then the X1950pro, and performs a fair wack better. weather this card is still here by fluke i dont know, but they have been quietly selling, when, imho, these cards are are, and have been, the greatist graphics card deal on the market for a while.
So if your thinking about picking up an X1950pro, take a second to look around for an X1900XT 256mb, or for that matter any of the cards from the quickly removed line of X1900s. There still out there, and they're cheap!
