$6100 dollars for 8 4Gb sticks from the apple store (configuring a mac pro). That's about $400 at newegg.
You're either lying or misinformed. You need DDR3 PC3-8500 ECC RAM for a Mac Pro.
Yeah I have the choice of sticking to DDR2 which is just as good as DDR3 in pretty much EVERY case. And they used to charge $9600 for 16GB of DDR2 a year ago when someone tried talking me into getting Mac. At that time I could get 8gb of DDR2 for $40 bux after rebates on techbargains. No it's not ECC but I DON'T WANT OR NEED ECC. Regardless, I have to start at $2500 base price just to get a computer without the monitor attached (I have a beautiful 24" and 30") already.
Besides the punchline of my post was, I would pay Vista prices for OSX but they're too snobby to disable the BIOS lock. So saying that leopard costs $29 is an effing LIE. It would cost $2499 for me and not only get software that's obsolete in 3 years, but an enormous piece of aluminum to go with it.
