After weeks of looking to buy my first gaming pc, I've realised I'll probably save a bit of money and end up with a better system if I attempt to build it myself. I'm looking for a PC that will be very fast to boot and use, be capable of multi-tasking, be able to run games at a playable speed for a good few years, and be fairly easy to upgrade when that's no longer possible. Are there any parts that I should change to save money/invest elsewhere? Will I need to overclock the CPU? I would be very grateful for any advice you can offer, feel free to tell me it sucks, thanks for your time!
