Costco has a 30 inch Dell monitor (3007WFP-HC) for $999. Does anyone have this and what's their opinions on it. I have an early '08 Mac Pro and want a bigger display. I'd love to have the 30 inch Apple monitor, but I'd also love to save $800!! (also, I'm guessing that this monitor will be compatible with my Mac Pro. It states that it "requires a DVI-D dual-link graphic card that supports WQXGA (2560x1600) resolution". Any comments on compatibility or other monitor suggestions?
