Whilst looking for a new gaming pc, i came across this http://www.freshtechsolutions.co.uk/custom-built-computers/intel-core-i7-4770-1tb-8gb-1866mhz-gtx-770-2gb-zalman-windows-8-gaming-pc.html Im wondering what type of performance i could expect from this pc on games like bf4 and whether any of the parts are outdated or if there will be any issues in changing parts. Thanks
