NEW PC - Help required

[chetansha]

Guys I plan for a upgrade - long after using my MSI K8N neo 4 plat and a dual core 3800.
I plan to buy either of this
Newegg.com - MSI 890GXM-G65 AM3 AMD 890GX HDMI SATA 6Gb/s USB 3.0 Micro ATX AMD Motherboard - AMD Motherboards
Newegg.com - ASUS M4A89GTD PRO/USB3 AM3 AMD 890GX SATA 6Gb/s USB 3.0 AMD Motherboard - AMD Motherboards

So What proccy / memory and PSU are recomended for this.
Usage - not for gaming.
