SATA will not make any noticeable difference. An IDE 7200rpm drive will be a little cheaper and just as fast. The exeption is the Western Digital Raptor 36.7GB and running at 10000rpm. I have one of these as I don't need huge storage, makes 7200rpm drives seem sluggish. Only very large and hugely expensive TFT monitors can handle resolutions higher than 1280 x 1024.
