I am looking to build a new gaming computer, and I have set aside a budget of £750. I need just the actual computer as I already have all peripherals/monitors. I am wanting to run games like Battlefield 4 on ultra settings, and would ideally like to have the ability to upgrade at a later stage, for example adding another graphics card/ new harddrives/ more ram. I plan to overclock so please take power and cooling into consideration. Things I don't need: Optical Drive, Operating system Things I need: Gigabit ethernet port, multiple monitor support, SSD for OS. I'm not fussed about the looks of the case, a simple black box will suffice is necessary. Preferably have an intel i7 if affordable (3rd gen or 4th) - Thanks in advance.
