Like the title asks, is there a bottleneck somewhere in the PC setup? Oh, and it's a PC for games like (resolution 2560 x 1920) BF3, LoL, WoW, Skyrim and AC: Revelations.
CPU: Intel Core i7 2600k / 3.4 GHz Processor - 8MB LGA1155
CPU-Cooler: Artic Cooling Freezer 7 Pro Rev2 Multi
Motherboard: ASUS P8Z68-V Pro - ATX LGA1155
RAM: 1600 MHz Kingston HyperX (4x2GB)
Graphics Card: ASUS EN GTX570 DC11/2DIS/1280MD5 - 1.25GB
Harddrive: Seagate Barracuda 7200.12 - 3.5'' SATA-600 1TB
Powersupply: Corsair Builder Series CX600 V2 - 600W 120mm
I'm considering buying another graphics card (Gigabyte GV N580UD-15I - GF-GTX580 1.5GB or the new ATI Radeon 7k series) and getting 16 GB Ram instead of 8, any thoughts on that?
