This is my first ever tom'sHardware post. I'll keep this as simple as possible.
My desktop is currently running the following:
GPU: Sapphire HD 7850
CPU: AMD FX-8120
Motherboard: GIGABYTE GA-970A-UD3
PSU: Thermaltake TR2 TR-500 500W (I used to have the Cooler Master Extreme 2 625W, but a friend suggested that that PSU might have been the problem so I changed it to the Thermaltake PSU. After I did that, the performance was still the same.)
OS: Windows 7
When I built my desktop I hoped that these specs would give a relatively good gaming experience but I've found out that my computer is struggling to run not very graphically intensive games (XCOM, GTA IV, Antichamber). The frame rates will drop extremely low even when I have the graphical settings at their lowest. For example, I can't run GTA IV for more than 2 minutes without the screen getting really choppy to the point that it's unplayable. Same with some other Rockstar games. Could someone help me figure out why this is? I mean, shouldn't those specs be able to run games pretty well?
I've tried re-installing all of my drivers but that did not change anything.
