Did I pick the right CPU? Is the Power Supply Enough?

I currently have: 750GB Seagate Barracuda HD + 320GB Maxtor HD
8GB Corsair Memory Some
Random DVD drive
460W Seasonic PSU (SS-460SGX) (It's a fairly old PSU, at least three years. Will it power what I have without much trouble?)
Windows 7
I'll be gaming and working on a 21.5" Asus monitor, 1920 x 1080. Will what I bought be reasonable for gaming on that level?

More about pick power supply enough
  1. get a Z68 platform + an i5-2500k instead, an i5 will have just about the same stock performance but overclocking the 2500k is where it's at, It'll easily beat the 3450s performance.

    as for the power supply I'd get a new one (from seasonic or corsair) because 460W is pretty much at the edge, also if you take into account the age of the PSU it'll probably just output 380-400W now. Get a 600W psu, a 750W if you plan on doing crossfire in the future.

    Good call on the 2500K + Z68 suggestion. There's no need to replace the PSU though, SeaSonic PSUs are the best of the best and that will put out over 400 watts on the 12 volt rail alone.
