I recently bought GTA 5 on sale and when I go to play it, I get lag when driving fast in a car. This is my current system:

Note that I also have a 650watt psu and I have PNY DDR3 1866MHz ram which is not on pcpp.
If I were to buy another 4gb stick of ram, would I see any improvement? Thanks in advance.

You've only got 4GB of DRAM, of that, the OS is taking a decent size chunk, imagine the video card may be 'sharing' some system DRAM, other start up items probably taking up some DRAM and 4GB is the minimum requirement, it calls for 8GB if you want decent performance

1 - check to make sure your ram is actually running at 1866 and not 1333 as some BIOS defaults to that
2 - run your task manager (Ctrl-Shift-Esc) and see if you're hitting CPU or RAM limits after the gaming. you might need to turn on logging for this.

I have already made sure that my ram is running at 1866, which it is. And when I had MSI Afterburner open while playing GTA 5, my gpu or cpu never maxed out but my memory did.
