As the forums belong to PC Specialist who build and sell custom PCs and laptops we can't advise on self build projects or competitors' specs.
You'd need to try an open forum like Tom's Hardware. You'll also need to tell them what you use the system for if you want advice on whether upgrading X component is 'worth it'. If it's gamong on a 1080p 60hz monitor the answer is probably no...
