1200 Dollar System

Hi, I am building a rig to use for the next couple years. I wanted something that has the power to play crysis and the room to use programs like Photoshop cs4.
Here's what I have.

Cooler Master RC-690
Gigabyte GA-EP45
Intel Core 2 Quad Q6600 2.4GHz
Artic Cooling Freezer 7 Pro 92mm CPU Cooler
G Skill 4 GB
Western Digital Caviar 7200 rpm 650 GB
Sapphire Radeon HD 4870 1 GB
Corsair 750TX
Samsung Black DVD-R
2 Apevia CF12SL-UBL 120mm fans
Artic Silver 5 Thermal Compound
Vista 64-bit

Is this a good set-up?
