if you had 400 dollars to upgrade what would you put in it? im looking to upgrade what i can for 400
With 400$ you might be better off building a new budget PC, as your current motherboard is very outdated and only has a Gen1 PCIe slot, as well as only supporting DDR2 memory, meaning any good gpus you can get will run slower than it was designed, and your ram will be slow in today's standards.
You didn't put your CPU in your question so i dont know if i can help you upgrade that, but again, your motherboard is ourdated and there may not be a worthy upgrade for you in terms of CPU.
Your motherboard only supports up to 8GBs of DDR2 ram, up to 800MHz, so if you dont have it already, pick up a a 2x4GB kit for DDR2 800Mhz ram. should only cost around 20$ but could be cheaper if you look around.
In terms of GPU i'd recommend a GTX 1050 Ti for around 160$.
But really, i'd recommend just buying a new motherboard. If your computer was a pre-built you may not have many options, as the casing for some older pre-builts are werid, and since I don't know what your CPU is I can't give you recommendations.
What I can recommend however, is that with a budget of 400$ you're better off just building a new PC instead of upgrading a severely outdated one.
