Better Motherboard and Graphics Card?

[jdigital]

Excellent, Till now this is what I have to buy:

CPU: Intel i5 2500K or Intel i5 3570k (In case of finding it more economic)
GPU: NVIDIA GTX 650 TI
Motherboard: Gigabyte Z77-D3H
Cooler: Cooler Master Hyper 212 Evo
HDD: Seagate Barrucada 1 TB 32 MB Cache
Ram: PNY 4 GB (1x4) 1333 Mhz (Already Buyed)

It is a good configuration.

Only do I have a dude, The Cooler Master 450 W EXTREME PLUS is good for the configuration or update to 500 W?

Thanks.
