I want to upgrade my PC to that max but i dont want to take out the motherboard. I need to know what are the best PSU and Graphics card i can get for around £100 - £150.

All information about my PC is here,

Everything you see is there apart from putting in a new 8 GB ram and a GeForce GT520 Graphics card.

I want something that will be able to play games with a high FPS (Minecraft ,L4D2 & Garrys Mod are the usuals)
