Ashwath Gopinath :
Im gonna be using it mainly for gaming and work. Games I play will be along the lines of far cry 4 and battlefield 4 (and hardline when its out). Need it to be £900 (but less is best ;-), dont mind if it goes around ten pounds over, no more than that. Only preferences i have-
1080p monitor
gtx 970 graphics card
nzxt phantom 410 case (looks great!)
Thats it, thanks for your time.
Have a look at this AMD build I just made right now for you:

£835 without peripherals and display unit.
This is an equivalent intel rig I just made now for you:

£842 without peripherals and display unit
Realistically you will have to spend a bit more than £910 (if you don't have a monitor) depending on what peripherals you plan on buying. That's as cheap as it's going to get while choosing CPU's that wont bottleneck your gtx 970
I think you can get away with spending £950 (again, if you don't have a monitor) if you buy £10 mouse and keyboard while using any old headphones.
Alternatively, you could save £60 by getting only 8GB of RAM instead of 16GB, and upgrade later on as 8GB will suffice for now, and use this money for better peripherals / display unit
Hope this helps !
