After I take the GTX670 and i7 CPU from a Alienware desktop to my new custom PC,I found that the performance (game plays) is lower than before. When I play Battlefield4 on my old one,it always works smoothly, but it will freeze sometimes on my new one.

I try to reinstall Windows and update new drivers,but it does not help.

The new one uses the same gtx670,2x4gb 1600 ram,i7 4770,1TB hard drive that I take from the old one. The difference between old one and new one is that I use the new case,new H87 mb and 750W psu (the old uses a 320w one).
