Computer Specs: RAM VS GPU

[ebenheizerm28787053]

Here is my current, so called, "workstation":

Processor: AMD A8-7680 (4 Cores, 4 Threads)

RAM: 4GB DDR3

HDD: 160GB (Yes, it is not SSD)

No dedicated Graphic Card

Yes, I know it's not the best workstation to playwith, but I have around $200 to ease the pain.

Which is better to do, upgrading the RAM to something like 16GB, or add a dedicated GPU instead? And if GPU, what GPU should work the best?

Thank you!

I hesitate to make a recommendation, but if it was my money i would go up to 16gb ram before gpu
