ninja720 :
Could someone recommend to me how to make this build a bit cheaper...
Thanks, AC
Also please recommend which GPU to use.

Sure, get a 3570k and a 1155 MB and save at least $50. 4670k is not worth paying more money for, even Tom's Hardware's CPU recommendations for gaming advise against getting "hasfail" over Ivy.
Additionally...because some will try to say IB is not as good, your extra $50-100 nets you a whopping 3% performance gain in real world applications, plus broadwell will be OEM only, so Hasfail is the only architecture ever going into socket 1150 until Skylake, which brings a new socket.
At this point in time, either Intel socket is a "dead" socket, so you may as well get the 3570k and OC as it OC's much better than hasfail, and runs much cooler, and draws less power.
Only reason to consider 4th gen Intel is if you're going to use the iGPU, but you have bought a HD 7970 GHz, so you are clearly not going to use that.

Performance[edit]
Compared to Ivy Bridge:
Approximately 8% better vector processing performance.[8]
6% IPC (instructions per clock) increase.
up to 6% faster single-threaded performance.
6% faster multi-threaded performance.
Haswell is around 10°C-15°C hotter than Ivy Bridge when overclocked and does not seem to break the 4.4-4.5 GHz mark nearly as easily.
Haswell draws around 30 W more under load than Ivy Bridge.[9][10]
A 6% increase in sequential CPU performance (eight execution ports per core versus six).[11][12]
Up to 20% performance increase over the integrated HD4000 GPU (Haswell HD4600 vs Ivy Bridge's built-in Intel HD4000).[13][14]
Total performance improvement on average is about 3% [15]
