Advice on components please

[Devlish]

Hi - currently have spec in sig, but id like to change my mobo, cpu and graphics card. I want to keep the 8GB of Kingston ram so i recognise that might limit my choice. I also have two SSDs and would like to get the most out of them. My budget would top out around £450.

Any thoughts appreciated.
