Hello, will these specs run the latest games (BF3, Skyrim, etc.) on resolution 1920:1080 at 1080p with HDMI?
CPU - Intel Core i5 2500K 3,3GHz
GPU - Sapphire Radeon HD6870 1Gb GDDR5
RAM - G.Skill DIMM 8 GB DDR3-1600 Kit
PSU - Thermaltake Litepower 600W
Ultra - no. Medium or high yes, but not at ultra. You'll need a far more powerful GPU to any sort of decent frame rates at 1080p. I also wouldn't get that PSU either - get a Corsair, Seasonic, or PC Power & Cooling Silencer.
