For £300, focus on upgrading your GPU to something like an RTX 3070 or 4070 for better gaming. Your CPU is okay but check if you need to upgrade it too. Look for deals and consider used parts for better value.
Hello, I bought my Optimus PRO without an OS because I already had a windows key. It came with the OS pre-installed and I authenticated. The issue is the driver to control the color of the keyboard lights is not installed and I can't find it online. Does anybody know where to find it?
