Hello. I am looking for some tips on possibly building a mid to upper range gaming pc as opposed to buying one. I am looking to get good performance on games like Call of Duty: Advanced Warfare and below on at least mid to high settings. I thought that a possibility for a CPU is an Intel Core i5-4690K 3.5 GHz, it is powerful and prices on Amazon at about $240. How should I go about looking for some other parts? I really would like to look at a possibility of building a computer, because you can get more power and use for less money than buying a pre-built one. I would also like to have the experience on building them. So, can someone provide some tips for me please? I would like to know mostly which other parts match the CPU I was thinking about and if the CPU would run games like Advanced Warfare well. For a GPU, I was considering something around an NVIDIA GeForce GTX 760M 1.5GB, and maybe 8GB DDR4 RAM. So, any tips really can help me, and thanks in advance! My budget is about $700-800.
