Greetings. I last built this computer in 2013 and even though it is running fine I have this compulsion to upgrade it. Is there anything I can do to increase performance without doing a complete overhaul? I know I can change out the GPU but any other suggestions would be helpful. Most hardware challenging games I play are Crysis 3, BF4. They work okay with the current setup but everything can always be better.
