OK guys, I have come into some spare cash (£300) and want to do something with my pc. My build is below and is mainly used for gaming. My question is what would you spend the £300 on to improve the system?
I already have a new mouse & mat, keyboard, headset and also have a sound card so don't need them. I run dual screens and have thought about 2 nice new monitors but wanted some other options first
