For added performance go into your Nvidia control panel and click on manage 3D settings. Look down the list for power management and click on maximum performance ( it's on adaptive by default usually ) I did this with my GTX 460 and my FPS improved quite a bit and it runs a lot smoother.... As it happens I've just order a GTX 670 and the i5 4570 haswell so I hope this works on that like it does on my GTX 460 lol
