Let me quote Fortune’s review:
Our review unit was a 21-inch inch iMac with 3.1 GHz quad-core i7 Ivy Bridge processor, 16 gigabytes of RAM, a 1 Terabyte “Fusion Drive," and a dedicated Nvidia GeForce GT 650M graphics card. That’s way more horsepower than most users will ever need.
I have the same machine and I absolute agree with Fortune. 😉
