Hey, I finally got the money together to buy my first gaming pc, and i would like to ask you for your opinions about it.

Planned specs:
MSI Z87-G43
INTEL Core i5-4670K 3.40GHz 1150 BOX
CORSAIR 8GB Vengeance DDR3 1600Mhz CL9 KIT CMZ8GX3M2A1600C9B
MSI R7970 Lightning BE 3GB GDDR5 PCIE + Never Settle Forever
WD 1TB Caviar Blue 7200rpm 64MB SATA3 WD10EZEX
ZALMAN Z9 Plus
CORSAIR Builder Series CX600W v2
COOLERMASTER Hyper 212 EVO RR-212E-16PK-R1

I can get the 7970 lightning for under 280x price (+games), and since they are just a rebranded 7970 anyway, I picked that.
Are there any problems with this? Will it be safe to OC my CPU to 4GHz? The case has 4 vents in it, can my PSU handle them with everything else? I'm not planning to oc my videocard (i know this version is built for oc-ing, but i can get it cheap, and i dont fell like i need it yet).
I hope this is a solid build.
Thanks in advance.
