how do you guys figure out the wattage are there any good wattage calculators like the xtreme one that is used by antec
also what should i put in for vcore at 4.0ghz to make sure i have headroom should i put 1.4
You make sure by running stress tests, what you want to do is put as little as possible.. most SandyB CPUs are doing 4Ghz with 1.25v
.. 1.4 is good for >4.8Ghz.
There's an excellent calculator present in one of the stickies above, but your two 560s on a SandyB platform need a very good 600W unit or a decent 650W.
List your budget and the places you're buying from.
ps. try to stick with a single, more powerful VGA.. although on paper things look promising for lower end SLI/CFX setups, you'll always have to deal with stuttering, artifacts and poor driver profiles(on some games) with such setups.. 570/6970(or a Sapphire Toxic 6950)/580 are better solutions than lower end multicard configs.
