So i've had this rx 470 for some months now..The 'Sapphire factory overclocked' version and i've been playing around with it.
Before i start here are my PC SPECS.~
CPU : i5-2400
RAM : 8GB 1333MHz
Motherboard : ASUS P8H67-V
Power Supply : Thermaltake 700watt-An average one.
1TB Samsung Hard drive.
GPU : AMD RX 470 4GB GDDR5.
Windows 10 PRO 64bit
Okay. Now that i'm done with the system specs here's my problem.
On games like league of legends i start with 270 fps -everything maxed out-.. then drop to 170 while moving around the map to get on my lane and then averaging 110 fps while the lowest fps gets dropped down to 80.
On Counter Strike Global Offensive i get around 150-270 fps averaging and the lowest 110...I have another build with an i3-4150 and an r9 270 performing similarly or better than the current build of mine.(the RX one)-but not much better on league of legends.-
If anyone could help i would highly appreciate it
