Hi, i'm rather new to PC parts and i'm looking to build my first PC. A friend of mine has offered to give me his GTX 770 which he does not use anymore. I have chosen my parts but i'm afraid my AMD x4 860k will bottleneck the GPU. I have a budget of around £300, would it be better to switch to a I3 CPU?
If you wish to take a look at my build here's a link to my spreadsheet. I'm open to suggestions
