New here. My son wants a computer to play this game. I recently bought a computer with the following specs: i5-4570s, 16mb DDR3 ram, 512GB ssd. My question is about the graphics. The computer has onboard graphics of Intel HD 4600 or something like that. Will this suffice for a decent gaming experience, or will a dedicated graphics card be needed? If a dedicated gpu is needed, I will need to buy another system because the desktop is so small that a graphics card cannot be added (already researched this). Would an external graphics card be any good, or should i just get a different system with room for a graphics card? Thanks for any replies!!!
