1440p is the way to go, that card can game on high with FXAA...which look stunning...FXAA or basically minimal AA level is perfectly fine for 1440p...FXAA @ 1440p is sharper than 16xMSAA at 1080p...and it does not look blurry.
390x. I have an MSI 390x Gaming and it's very impressive. When I'm not gaming, the fans are off and it's quiet under load. It's got a huge heat sink, but be advised its a 2.5 slot card. Other than the Msi Gaming, I would recommend Saphire or XFX. However I can't recommend ASUS or Gigabyte AMD cards.
