I'm running P5Q Pro with Mushkin Redline RAM. If you want the ASUS equivalent with only 1 video slot, then it's P5Q (which is also a tad cheaper, depending on where you get it).
You've nailed down the top choices for the usual P45 suspects. If you want 16 phase power on the mobo, then consider Asus P5Q Deluxe or Maximus II Formula.
Your listed Corsair memory is great. Consider also Mushkin or G.Skill.
