If you use Nvidia cards, I absolutely recommend this monitor right here - http://www.newegg.com/Product/Product.aspx?Item=N82E16824160226&nm_mc=TEMC-RMA-Approvel&cm_mmc=TEMC-RMA-Approvel-_-Content-_-text-_-. Comes with G-Sync compatibility and a 144hz refresh rate. And it's 1080p, which is the only resolution where you'll get framerates that high. Hope this helps!
