I use a heavily modified Mac Pro 6-core 3.33 gHz machine. It has 24GB RAM, 8 TB of internal HD storage including a 640GB SSD boot disk, and two fast graphics cards driving 3 large monitors. Scores just over 16,000 in the GeekBench benchmark suite. I use it for surfing the web and writing email.
I also run Adobe CC Photoshop and Premiere on it when I'm doing real work.
