I already showed you the Lenovo Z710 59400485, which is very powerful and offer 1080p and 17.3 screen... very good for graphic design.
With a disgustingly bad display. Only 66% sRGB coverage (and 49% AdobeRGB coverage) is way too little for any serious designer.
If you want an objectively good display there are few options. There are some configurable Dells and Clevo's (barebones) where there is a high-gamut display option that's fantastic, but they go a bit above your budget price-wise.
I'd really look into a second-hand Mac. They have great displays without exception and you can always run Windows on them.
Or a second-hand Vaio Z. They aren't sold new anymore and they're all 13" but real performance beasts at weights even most ultrabooks have difficulty reaching. The last models were configurable with a proper Sandy Bridge (or even Ivy Bridge) quadcore and the displays are incredibly good for a laptop. But 13".
