Well the RAM i was thinking to get
G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600
What do you think
The RAM should work fine.
Most people, when checking RAM compatibility, take the following steps:
1. Go to the manufacturer's support page for your mobo (google the make & model of mobo)
2. Look for a list of Tested Memory or Qualified Vendor List or QVL
3. Look for your RAM on the list.
