You can get good DDR3 RAM with 2x8Gb sticks for about $125. If your after gaming RAM with the best timings its upwards of $180-$200 for same quantity.

I never buy games at full price. As a computer gamer I will buy from GOG, Steam, Origin, etc. when they are on sale. I love the Battlefield series and had 1500+ hours into BF2, but I will never drop $60 on the new BF4.
