is this build future proof? because im planning to use it for quite some time
Building for futureproof? Nope.
None of the rigs recommended here is futureproof. Cause nothing is futureproof. Paying more also does not equate futureproofing. Upgrading it once every year is then futureproof.
Like it or not for pc to be futureproof you will need to update it constantly. Now you buy a b85, h87, z87 mobo all slowly going to be replaced by h97 and z97. Few more months down the road a new chipset is available.
Gpu. Now nvidia has is the 700 series, end of 2014 there is a 800 series. How long have 700 sreries being sold in market? The most 1.5years.
Cpu, there is not much leap of performance from sandy bridge till now. Yet every 1 year plus hey come out with a new cpu.
Buy what you need and what you can use.
