You must still be stuck in the NetBurst days of the P4. Core (2) Duo (Yonah/Merom/Woodcrest/Conroe) chips stress processes per clock cycles and power consumption over raw clock speeds. In the mid to high-end processor market Intel has overtaken AMD with custom builders. It's just a better buy all around.
You know a 750W Power Supply is pritty much redundant in almost all but the most over powered or hard drive filled machines so it's needless costing you and the environment when a 500W would probably suffice you. Larger numbers don't always mean better.
750W is the theoretical limit. Devices plugged into the PSU only use as much power as they need. Having a PSU with greater wattage is just a safety net when devices start to use more power in the future.
