Where's my bottleneck / what should I upgrade (cheap budget system)

[nmkloster]

I've built a really cheap system which works ok for older titles. It scores 460 in a Heaven Benchmark so pretty low-end. If I decide to upgrade one component is there a clear choice for which one to upgrade? The total system cost me about 250$ so it might be something like whatever I can find used for 100$ in 6 months or so.

Specs important bits:
Intel Pentium G4400 - it's socket 1151, so maybe an i3 or i5
GeForce GT 730 2GB - passive cooling is a big plus but maybe it's limiting my options
8 GB RAM 2133mhz ddr4 - single stick so a second stick is my first though for an obvious upgrade

Less important bits:
MOBO: Asrock H110M-HDV - the one thing I bought from new
PSU: BeQuiet 350 Watt - I think the system is currently drawing less than 150 watts
HDD: 120 GB SSD Kingston Fury
Chassis: Custom cardboard and glue creation

Your GPU is your weakest link. I would look for a 1050ti for around $150 and it will be a good improvement over your 730 as the 730 is not much better than integrated graphics.
