Upgrading from a 19' 1440x900 display to a 27' 1920x1080 display

How much of a leap is this and will I notice a difference in terms of resolution? I know that I will obviously notice a difference in size, but will 1080p suffice for such a large monitor?

I mostly use my computer for playing games and browsing the web.

Also how much of a performance cut will there be? I have a gtx 670

Well there will be a noticeable hit to FPS, but a 670 should handle it fine. 1080p will be fine for this size.
