Cybra.Net : Geekery Abounds

For anyone else confused on the new graphics options on the March 3rd iMac release, here's how to compare them:

GeForce GT 120 = 9500GT
GeForce GT 130 = 9600GSO = 8800GS (a rebrand of a rebrand)
Radeon HD 4850

Tom's Hardware has a nice chart of the relative power of each: http://www.tomshardware.com/reviews/geforce-gtx-radeon,2151-6.html

Since I'm going to be consolidating my 'game' machine and my mac into one, I think it's going to be well worth it simply to upgrade the 24" all the way to the 4850.
