Today I bought an Asus A8N-SLI motherboard, and next week, when it arrives, I will be putting a dual-core Athlon X2 3800+ in it :D I couldn't be more excited. Besides some issues I had regarding the Nvidia Firewall, and having to reinstall windows (I was due for a reinstall anyway), I've had no issues whatsoever. I overclocked my current Athlon 64 3000+ to 2.0 ghz from 1.8 ghz, and it still runs much cooler than it used to thanks to the silver-based thermal paste I applied. It now idles at 36°C when before it idled at 45°C at stock speed! I plan to overclock the X2 to 2.2 ghz, or 2.4 ghz, I will decide when I see what temperature it runs at.
