If you stop applications that keep the system very busy as soon as there's a power failure, then you don't need more than 2-3 minutes. Once the system is idle, you'll have lots of time to shut it down.
im thinking of either getting another 5850 or getting 1 gtx 680... and @orlean i need PFC compatible PSU so i can make a claim if my thing blows up while using a UPS.. I've heard people being denied because of that. especially from cyberpower.. but i was looking at some apc ones.
