After seeing the dell 27" ips 1440p monitors on display im really itching to upgrade my crappy westinghouse 27" lcd. Being that I do play some fps games and mmos im not sure if I have the system to properly make use of 2560x1440 though. Should I just upgrade my crappy 1080p lcd to a 1080p ips display or go full out on a 2560x1440? Or can my core i7 950 and gtx 670 not handle that?
