~2 weeks until my new PC is shipped, built, and bf3 is installed, and I am once again the noob (wait, I always was a noob

only real question I have is do I need any of the DLCs? I'm assuming back to karkand, but what about close quarters? don't want to buy it if I don't have to yet.
specs for those who care:
Antec Nine Hundred
Thermaltake Black Widow W0319RU 850W
CORSAIR Vengeance 16GB DDR3 SDRAM DDR3 1600
SAPPHIRE 11200-01-20G Radeon HD 7850 2GB
AMD FX-8120 Zambezi
GIGABYTE GA-990FXA-UD5
random assortment of peripherals and whatnot
looking forward to fighting with y'all once again.
