Upgraded Computer

[Ogloo]

Right now I am upgrading my old computer, and I am about to order all the parts I need to get to upgrade my computer, but I opened up my computer and saw that there a lot of wires and pluggs in the inside connecting these different cards and stuff.. Do I need to upgrade these or buy some special cords that might not be in my computer because im getting new products compared to my old computer?

This is what im getting

The mobo from amazon is better, after 3 bad experiences ill never get anything "open box" ever again, id rather pay full price and avoid the headaches. I dunno what kinda budget your working on, but for my i7 I used the evga x58, the 299.99 one. It has a lifetime warranty! To me thats worth the extra money for it.
