Thus far, mine has been AMAZING!

So I upgraded from a 939 Ultra-D DFI Lanparty board w/ 4400+ and 2GB patriot PC3200 ram, single SATA drive on water cooling, pushing 2.75GHz and crap ram timing (I think my board hated me, 251Mhz+ FSB was worthless, despite any other setting) to a DFI Infinity NF570, 3600+ brisbane, and 2GB Patriot LL 800Mhz ram, w/ 2 Seagate 320GB 16MB cache drives in RAID 0.

I started pushing on this processor, currently aircooled (stock cooler, w/ ceramique) and it would not stop climbing! I find myself w/ 16 hours stable of orthos love on 285x9.5 (2.7Ghz) ON STOCK VOLTAGE. Thats 1.3V on stock air cooler, running mid 40*C under load. I have the water cooler ready to slap on, just waiting on a radiator and to get my new case built. Gonna try for 2.8Ghz on stock voltage/stock cooler before really pushing on it

Just curious what anybody else is running...

My 3600 X2 Brisbane did fairly well, but not as well as I had hoped.
2.7 was fairly easy to reach on air, but anything much over that required serious tweaking (on Asus M2N32-SLi Deluxe). I think I ended up with around 2.8 before putting my single core 3800 Orleans back in.
I should revisit the X2 though as I need to reclaim some hwbot records I lost since I took the CPU out of my AM2 rig.
