First off: thanks for actually replying those who did, and giving suggestions. I wanted to clear some of the reasons why I picked those parts.
The reason i picked out that PSU is because I don't know how much all of the components will draw from the wall (Its the only thing i didn't check/work out) and it seams high enough that I can get new, better GPUs in the future.
I would get a better card that 950s but as I said up top, I have one already so its just to keep the price lower. I've only had the card for give or take 4 months so its fine right now.
That being said, I have looked into some 4gb 960s and I *might* be able to.
The reason why there is 3 separate drives is so I can have everything installed at once. I tend to install A LOT of mods for games like Fallout 4 and Skyrim and that takes up 1/5 of my storage right now so... yeah I want a lot of storage.
Finally, the reason why I want the i7 and not the i5 mainly due to the better clock speed and hyper-threading but also because the i7 isn't really that much more. The cheapest 4ghz clocked one i found (in 5 mins of searching) was £290 and the cheapest 6600k was £220 so quite close for minimal effort searching. I'm sure if I looked harder I could find one for £250 but for the matter of £70, It isn't that much but I might get the i5 if I start to get low on funds.
Thanks lads!
