This is why many of us are waiting. Old, outdated video card options (a year and a half or older technology), lack of 2 gb standard, and the obscenely offensive BTO option prices. Apple has yet to adjust their BTO pricing to compensate for the Intel price drops. The move from 2.66 to 3.0 costs an offensive $700, when in reality the difference is about $310. And the even more offensive from 2.66 to four-core 3.0 costs $1499, when in reality the difference is about $400. Let's not forget about Apple wanting $320.00 for a 500 gig hard drive. I could buy THREE 500 gig drives for that price and still have money left over. But, anyone who purchases extra RAM and hard drives from Apple is either a fool or woefully misinformed.
Bottom line, it is a mistake to pay Apple $2499+ for outdated video cards and an overly-expensive standard configuration.
