This is my proposed build, wondering if there's any issues that anyone would see. I would be Running ArmA 2/ 3 When it comes out plus BF3 on max graphics looking for it to run cool w/o overclocking and do you have any tips on the build
Both builds feature i5-3570K and GTX670, so any differences will be piddling. Otherwise, there is too much Crappermaster in both of them. In any case, any new gaming PC built today should be Intel, not AMD. Take a look at Rosewill or Antec for cases, and Xigmatek, Corsair, or Noctua for CPU coolers.
