hey guys, i'm kind of new to the whole building my own pc so i bought a premade one which has the following:-

Intel Core i3-4170 CPU @ 3.70GHz
8GB DDR3 RAM
Windows 10
Nvidia GTX 960
and i believe 1TB memory

i'm looking at getting a cheap budget roughly around £90:

Intel Sandybridge i5-2300 Core i5 Quad-Core Processor (2.80GHz, 6MB Cache, Socket 1155)
or
Intel Core I5-3470S Processor (2.90GHZ, 6MB Cache, Socket 1155)
