Hi, so I'm looking to build a gaming pc for £50. I was thinking I could use the i3-550 dual core, but am a bit lost as to what else. I'm aiming to run csgo at 1080p and 60fps plus, all second hand stuff probably on ubuntu. I know it's possible as i have a friedn whose done it. The case monitor mouse keyboard etc. are no issue and not factored into the price, any pointers would be greatly appreciated.
