*** First impressions:
Ordered this x800gto from monarchcomputer for $180. Didnt even remove the heatsink, just went straight to tweaking it. In my system it shows up as an x800pro for some reason, maybe because the included Cat 5.7 driver doesnt have a profile for the gto yet. Anyway, the cooler is copper, and has a real fan, as opposed to one of those "water paddle" type things that seem to make a lot of noise and not much cooling. Lets just say that this cooler is quieter than the one on my sapphire x800 vanilla, even at full speed. Also, it only reaches full speed during POST, during regular gameplay it stays pretty quiet, around 43% speed or so, while keeping the gpu temps around 65C, but I have good airflow in my case, so that's probably helping as well.
*** Overclocking:
Decided to first stick with 12 pipes and see how far I can push it. On stock cooling, the max gpu speed is 579mhz, and the max mem speed is 589mhz with the fan at 100%. (Stock is 400/490). I decided to use 570/570 as a safe speed. Then, I reset the fan, and thinking I turned it back down to stock speeds, I proceeded to run 3dmark05 to get a whopping 6000 even. Shocked, I checked the clocks and sure enough, it was still running 570/570. I was logging the temps during the test run, and it showed 75C max. Did I mention this card had a nice cooler? When I reset the speed correctly this time, the score came out to a more predictable 4541.
*** Unlocking:
I successfuly flashed the modified 16 pipe bios, and went to tweaking again. Turned the fan up to a reasonable 70% and it ran stable at 570/570, temps hovering around 70C under load. Ran 3dmark05 again, and this time got a score of 6688. For a $180 card, nothing else even comes close. I have a zalman vf700cu from my previous card - I'll install it tomorrow and see how much farther I can push this card.

UPDATE:
Installed the zalman cooler. The good news is it stays around 55C under load. The bad news is I only got another 10mhz on the mem, and nothing on the core, so I'm stuck at 570/580. Looks like I need more voltage, so I'm gonna try and pencil it this weekend, maybe I'll reach 600.
