You need triple channel memory for the i7 build, so something 3x2gb or so.
The G.SKILL Phoenix Pro Series is a better faster SSD
You don't need a 850 watt power supply for one mid line or even one high end video card. A good quality 500w from Seasonic, Corsair, Antec, Enermax or similar quality will be fine and will save you a couple of bucks.
40.00 for a fan is a bit expensive.
Finally... Consider building it yourself, you will save a lot of money, and people here love to help newbie's with new build questions.
