Worth it to sell G4 for ACD?

[simplymuzik3]

Hi, I have a powermac g4 quicksilver, dual 800mhz, 1.5gb ram, superdrive, 120gb HDD. Im going to try and sell it for about $330 CAD. With that money I could buy an Apple Cinema Dispaly 20" for about $320 CAD. Do you think I should do this? The quicksilver just sits in my room and its waiting to be sold. I currently have a 22" samsung syncmaster 226BW which I think is a really nice monitor(I think its TN panel, but It still look damn nice!). Will I notice the 2" decrease in size? Is the cinema display IPS(or whatever its called)? Its not the old white style display, its the new imac looking display. Let me know what I should do. Btw, the cinema display would be hooked up to my powermac g5(main computer) through DVI connection. Thanks for the help!
