    Hello again, i've put together an intel cpu build with the idea of having a cpu to last me a few more years with the drawback of having an older video card, could you tell me if these parts are all compatible please?

    Motherboard : ASUS Z170-P ATX Skylake Motherboard Asus Z170-P Intel Skylake Crossfire ATX Motherboard
    CPU : Intel Core i5-6400 2.70GHz (Skylake) Socket LGA1151 Processor
    CPU fan : be quiet! Shadow Rock LP CPU Air Cooler
    RAM : Corsair 8GB DDR4 Vengeance LPX 2133MHz Memory Kit for Skylake
    PSU : Corsair 650 Watt VS650 Standard ATX PSU/Power Supply

    Is there anything else i would need? Or even anything that needs to be replaced? I also have an amd pc build with jackfrags build used as a templated but i wanted to see how this intel build would do, so any respsonse would be much appreciated

    Answer by shaund on Monday, December 7, 2015
    Hi Rishi,

    Yes all of those components are compatible, personally I'd just use the stock CPU cooler that comes with the CPU as you will not be able to overclock it and spend the extra money on getting a GTX 950 rather than the 750ti.

    Question  64 bit support by Chris


    Does this CPU Support 64bit windoows 10? I cant work out how to see of a cpu is 64 bit.


    Answer by shaund on Sunday, November 15, 2015
    Hi Chris,

    The CPU will support a 64 bit OS, you'd be hard pressed to find a modern CPU that doesn't, as long as you have more than 4GB of RAM in your system you will be fine.

    Question  Question by Mark

    Answer by shaund on Tuesday, November 3, 2015

    Any CPU cooler that fits the 1150 socket will fit the 1151 socket.
