Monitor Samsung SM214T, SM215TW ili SM225BW

Razmišljam o kupnji novog monitora i sad se dvoumim između ova 3 gore navedena Samsung SM214T, SM215TW ili SM225BW. Specifikacje su im:

Samsung SM214T.......21" TFT, 1600x1200, 300cd/m2, 900:1, 178°/178°, 16ms, Silver, Premium stand (Pivot/swivel/tilt/height adjustable), Narrow, Analog/Digital, TCO'03........6000kn

SM215TW .......21" TFT, 1680x1050, 300cd/m?, 1000:1, 178°/178°, 8ms (G to G), Silver/Black, Premium stand (Pivot/swivel/tilt/height adjustable), Narrow, Analog/Digital/CVBS/S-Video/Component, TCO'03.....5500kn

SM225BW...........22" LCD, 1680x1050, 280cd/m2, 700:1, 160°/160°, 5ms (G to G), Silver/Black, Premium stand (Pivot/swivel/tilt/height adjustable), Narrow, Analog/Digital, TCO'03.....4000kn

Zanima me ima li tko kakvih zamjerki kojem modelu, i koji je najbolje uzeti. Treba mi za rad u autocadu i photoshopu, prvenstveno radi obrade fotografija.
I treba li se ravnati po modelu, koliko para toliko muzike???????!
