Hi,
I want to build a new PC for home usage and some (not hardcore) gaming. I want something with best price/value ratio. My current idea is:
GPU: Sapphire HD 7870 GHz Edition 2GB DDR5
CPU: AMD FX-8320
SSD: SAMSUNG MZ-7TE120BW
HDD: WD Blue WD10EZEX 3.5" 1TB
RAM: 2x Kingston KHX16C9B1B/4
PSU: Corsair VS450
----
Together about 1000USD including 125USD for motherboard, but I have no idea wich one to choose (I dont stgrictly insist on 125USD budget). Can you please recomend something to me? And if you have any suggestions (eg. some component is weak spot or too good for others), how to improve my idea, I would be very gratefull. Thanks

General Thoughts: Get a board with an AM3+ socket. Asus and Gigabyte are the top two brands in quality right now, but ASRock boards are also very good. If you plan on overclocking (something the 8320 is very good at, even on stock air cooling), you'll want a board based on the 990 chipset, if you don't want to overclock, save some money and get a 970 based board.

I've always had very good luck with Gigabyte (less so with Asus). The GA-970A-D3P is a newer version of the 970 board (with an FX8350) I'm using.
 
It's not the chipset really that determines overclock, it's the VRM's. Generally the 970 board have less VRM's than the 99FX/990FX chipsets. The difference is in the number of pcie lanes for crossfire/sli

970 - 16x/4x
99FX - 8x/8x
990FX - 16x/16x

If you don't plan to link video cards, 970 is good enough but usually those boards don't have enough power phases to do a good OC, but the 99FX/990FX boards usually do.

I just switched my Asus 970 for a 99fx, which went from 4+1 analogue VRM's to 6+2 digital controlled and was able to overclock another 400-500mhz with only changing motherboards.
