my PC I would like to upgrade something to gamble Battlefield 4 or other quality game better. My hardware is actually quite passable with a very good i5 processor and the graphics card NVIDIA GeForce GTX 660. The problem is probably my memory with only 4 GB (a tie). Which I would like to upgrade. The only problem is that 8 GB is soon enough, but for me 16GB something is too expensive. That's why I wanted to know if it is possible to upgrade it to 12 GB? I would like to do with 2 GB 4 bars. What should I watch everything, so that no serious problems arise?
Thank you in advance and still happy holidays.
