I am going to guess that you are looking at the Intel® Core™ i5-3450. Based on the selection of the Gigabyte GTX 670 and 8GB of RAM it looks like you are trying to build a gaming system. A good performance board for the 3rd generation Intel Core i5-3450 would be something like the ASRock Z77 Extreme4 or something with a little longer warranty you can check out the Intel Desktop Board DZ77SL-50K. Both will work well with the all the items that you have listed.

Is the Gigabyte GA-B75-D3V good? In my country, the Z77 is pricy, but the B75 is what I have money for! One more question : will the GTX 670 keep me 3 years with very good graphics in games? Thank you!

PS: I also have money for the P75-D3.
