Please don't get AMD, for DCS especially. If you want to play with low frames in DCS, then go ahead. Ideally, you'd want to get an i7-4790k, possibly the fastest processor out there. It's costly but its worth every penny. If you can't afford that get an i5-4690k. Failing that, get an i3, even those are faster than AMD. You could probably get a bigger SSD say 256GB. Vid card, get an nvdia 970 if possible, if not a 750ti is adequate. I have the 750ti, it's pretty good but you can't turn all the graphics details to high.
I was an AMD user earlier and I regretted buying AMD the day I put an Intel inside. The difference in DCS is night and day.
