Well, my setup is an AMD Phenom II X4 840T with stock clocks and Sapphire R9 270X. My motherboard is an ASUS M5A97 LE R2.0. I have 12GB of RAM, 8 of which are GSKILL Ripjaws, they are DDR3 1600 the other 4 is 1333, which is causing my ram to be slower than it could be, but i have no need for fast RAM. So my question is how bad is my system bottlenecked due to my semi-old processor? I will be upgrading to an FX-8320 when i get the money, but until then im stuck with my faithful Phenom II. My second question was how to figure out wether or not there is a bottleneck, also the Sapphire R9 270X is running in a PCIE X16 2.0 slot.
