I'd vote for the GHz... its harder to upgrade that the pixels.
Get a Dell 20" now and when you have more money get an Apple 23" screen, or just get 2 Dell 20" screens. That would be extremely helpful, more so than a single 23". And you can upgrade them later for Apple's 23" displays...
Same with RAM. Get however much now (not from Apple!) and then upgrade it later, slowly.
