Hey guys! I didn't know where else to go because I've been looking all morning on google to find an answer, I recently acquired some fairly old Desktop PC's from my boss who usually spares no expense when it comes to building them, and I pulled out what says to be a "X1900GTO" i cant seem to find anything about this model specifically just talks about ATI delaying the release back in 2006, also the heatsink/shroud looks different than other ones I see which I believe are just the X1900GT and XTX. Thank you!
