I would just build one yourself nVidia graphics card seems to work best with DCS, I would go with an AMD CPU but thats just my personal preference nice big solid state drive corsair? Beefy PSU half decent motherboard 12 gigs of ram DDR3.
Then you'll still have some cash leftover for beer. :thumbup: Maybe even use some of the leftover cash on a decent heatsink for overclocking the CPU. You could go the Alienware route but you could just as easy build your own and likely for cheaper. :smartass:
