Hi, my 18th birthday is coming up next month which will give me enough money to upgrade part of my PC. Sadly the PC is starting to not be able to run games at 1080p 60FPS even on the low settings (such as in the new battlefield 1 Beta I get around 40-55FPS if im lucky). The price limit for this is £300.

With that all said, what part of my PC do you think I should upgrade first (with a recommended replacement if possible), my current specs are as followed:

CPU - i5-3330
GPU - Palit GTX 660
Motherboard - Gigabyte Z77-D3H
RAM - (unknown brand) 8GB 1333mhz
I am also using a 500W power supply (just incase I would also need to upgrade that aswell)
