I currently am running an A6 5400k CPU, MSI FM2-A55m MOBO, 8GB Corsair Vengeance RAM, and 500GB SATA HD. I have enough to get a AMD 7770 GPU, and a new power supply, I was thinking a Thermaltake TR2 TR-700 700W ATX 12V V2.3 & EPS 12V SLI or a RAIDMAX RX-635AP 635W ATX 12V v2.3/EPS 12V SLI. In a few months I will have enough to get an Intel Core i7-3820 Sandy Bridge-E 3.6GHz (3.8GHz Turbo Boost) LGA 2011 130W Quad-Core, and was thinking of getting a MSI Z87M-G43 LGA 1150 Intel Z87 HDMI SATA 6Gb/s USB 3.0 uATX Intel. I am very new to computers and Have 1 build under my belt. I am getting the psu and gpu soon, and then replacing the mobo and cpu in a few months. I am an avid gamer, and have been running into issues with Arma3, which I never had on Arma2 with my current set up. I would like to set the graphics to the Ultra setting or something extremely high. Like I said I'm new, so I might not understand If something is compatible, sorry in advance.
