Probably a better place for this would be the "Can I Run It?" thread, but anyways. Arma 2: OA is a very CPU dependant game, and then on top of that DayZ makes it even more CPU heavy. AMD CPUs are really not the greatest performers for gaming. Your graphics card is fine and should be able to play DayZ on high. The 6870 is quite a powerful card, but they does not help you when you're recording with fraps, dxtory, xsplit, etc. The problem about all of these programs is that they are very CPU intensive so they would further reduce the already lower than average performance of that processor. Another thing to take into account is if that computer only has one hard drive, which I believe it does, your performance will also be quite poor. DayZ really does a number to your hard drive and so does recording, so what I would recommend is to get another hard drive into that machine at least just to record to. Make C: drive your operating system and game installs, and then make D: your recording hard drive. To be honest I would save up the extra money and just build a machine for about $1200 so that you get a solid intel CPU, maybe a higher end GPU and another hard drive. If you're not recording, that computer would be fine for medium to high settings in DayZ, but with recording it would be surprising if you could push 30 fps on the high preset. TL;DR: That computer is not the greatest for recording DayZ, you would drop below 40-60 frames easily on medium-high settings while recording. I would recommend a second hard drive to record to, and an intel CPU like a i5-3450 or higher end to record with.
