I'm making my first ever PC build with my friend (he's done multiple). I was going to get the Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory for $95 (au) but one of my other friends has just offered me his old G.Skill Ripjaws X Series 16GB (4 x 4GB) DDR3-1600 Memory for $100. He bought them in 2011, used them for two years without any problems and then stopped using them (but he didn't have any troubles). My build as a whole is this - http://au.pcpartpicker.com/p/1rIk9. I would like 16gb but it's not a neccessity.
What do you guys think; the Corsair or the G.Skill?
Feel free to comment on the build as a whole, I'm open to feedback, and all opinions would be appreciated.
