Just finished a system with the EP-9NPA+Ultra. Great mobo, highly recommended. Socket 939, nForce 4 Ultra chipset, non SLI.
Some highlights: - support SATA II with 4 onboard SATA ports - 6 speaker outs, coax, and digital S/PDIF on the mobo backplane - 2 right-angle SATA cables and 3 rounded cables included - a blue the LED for RAM, CPU, and video card that indicates if each part is not seated correctly - 2 digit LED on mobo to indicate error codes when booting - power and reset switch on mobo so you don't need to have case hooked up to test post - 3 BIOS controlled variable speed header pins for case fans Stable as all heck. Running Athlon 64 3000+ at 2.4 Ghz at stock voltage with fairly cheap ram. Oh yeah, and the GTO2 I put in it unlocked just fine and overclocked to 490/590 :) -- Brian
