yeah i think if you hook up your comp to a nice lcd tv via dvi-hdmi you can use 1080i/p which would bring your res to 1920x1080 and it would be sweet. i play on my friends 60" samsung dlp and its astonishing. his 8800gtx handles it just fine too.
a mac screen would be sweet too though. they're kinda expensive though, but if you can afford it go for it.
