Would this computer run DayZ Standalone at good FPS?

Solution
1. Swap out the motherboard for a Z97 model. No point in using a Z87 board at this point unless you really need to save that $10. Also the CPU you picked is the new Devils Canyon refresh so you may end up needing to flash the bios of a Z87 board for it to be compatible (depends on board of course) so make your life easy and go for a Z97 variant.

2. Ditch that SSD. You're paying WAY to much for such a little amount of storage. Unless your only going to load the OS and your game, your going to find yourself running out of room real fast. With SSD's you generally want to make sure you leave them some breathing room for Trim, you dont want to ride it to capacity. You can pick up a Samsung Evo 250GB for the dame price on Newegg...

3. Almost forgot, swap out the 4x4GB sniper for 2x8GB. Its a price difference of about $3. The boards you're looking at support up to 32GB, no reason to fill up all the banks with 4GB sticks if your going to ever upgrade because you'll have to completely swap out with new memory instead of simply adding to existing memory.
