I'm planning a new build at the moment, but I don't do it very often so i'm a bit out of the loop and looking for opinions. I'm looking to do an AMD/ATI build since CrossFire seems a more economical option than SLI.

Current build:
Motherboard - ASUS A8N-SLI Deluxe
CPU - AMD Athlon 64 X2 4200+
Memory - 4GB Generic DDR
Graphics - BFG GeForce 9600 GT OC
PSU - CoolerMaster Real Power M1000 (1kW)

Planned build:
Motherboard - MSI 890FXA-GD70 £165.15 (~$250)
CPU - AMD Phenom II X4 955 3.2GHz £128.50 (~$195)
Memory - 4GB Corsair TwinX XMS3 Classic £120.97 (~$183)
Graphics - PowerColor HD 5830 PCS Edition £164.49 (~$248)
PSU CoolerMaster Real Power M1000 (1kW)
