Borderlands 2 on i3 2130 + Palit GTX 660 OC gives around 25-30 fps. Both cpu and gpu load about 60%. Psu 500W. What is the pro

Solution
Download Rivatuner Statistics Server (RTSC) and set the framelimit to 30 FPS when playing borderlands 2. The thing which is wrong is the game, not the computer.


ram kingston 2x 4gb 1333 mhz hynix memory blocks http://www.memorybenchmark.net/ram.php?ram=Kingston+99P5474-013.A00LF+4GB
hdd seagate barracuda st31000524as
motherboard biostar b75mu3b
win 7 ultimate 64 bit, all drivers latest
looks too bad for 50$ ram

battlefield 4 runs ok for such config, cpu load always around 90%

Made some tests:
Memory Mark
This Computer 2049
Memory - Latency
This Computer 26.5
 


Even at lowest settings the framerate is poor. The thing is cpu and gpu are not loaded properly.
Borderlands 2 and Mafia 2 are the only 2 games that have unexplanable lags on my pc. Mafia seems to have some game engine problems, it lags even on GTX Titan.
