It's doing ok, relatively silent as far as vidcards go (and it's audible compared to my previous passive-cooling 2600HD Pro), and given that it has 2 DVI ports, I'm sorely tempted to go dual screen as soon as I can find a way to justify it to the wifey. hehe If I had an lcd tv with HDMI, that would be the next option.
The thing that's giving me trouble now either seems to be my ram or the mobo's memory controller/chipset. Unfortunately, there's no diagnostics for the mobo, although running primetest95 helped me identify a potentially bad stick of ram. Time to go for a 2x2 Gb configuration... sigh.
