I'm looking to build a new gaming rig and have come up with the following parts. Kindly let me know if I'm making any mistakes in my choices.
Motherboard: AS Rock Extreme 4 990fx
CPU: AMD FX – 8150
RAM: G-skill Ripjaws X (4GB x 2)
HDD: Western Digital Caviar Blue 500 GB
Graphics: Sapphire Radeon HD 7850
PSU: Corsair TX 650 or GS 700
Cabinet: Cooler Master HAF 912 Advanced
Would the PSU be sufficient in case I decide to Crossfire after a year or so. Your help is much appreciated.
