Hey, I need to buy a system (all but a gpu) that I could put my r9 280x that would produce no bottle neck and the correct power pins and wattage (8+6 pin)
Thank you!
Well I wish you the best of luck, but no bottleneck is super hard to achieve. It depends on not only the hardware you use, but the settings you select in each game. So you might run into a graphics bottleneck on one title and a CPU bottleneck on another.
Your ideal situation would be a GPU bottleneck. That way you have more CPU than the graphics card can use, leaving more resources for the rest of your system, and getting the most out of the GPU.
