Before you rush into 16 GB, keep in mind that- having more RAM than recommend is useless. 8 GB will actually handle it. It seems like your processor's (CPU) clock speed is a bit low too. You might consider getting a better CPU. But wait for new Cpus to come first, maybe you can check the benchmarks of new ones releasing. About CPU, take suggestion from someone who's more experienced with it. I have i7 4790k, but it might be overkill too. I don't know tbh. So, if you don't have tight budget, take 16 GB RAM. And do some research on CPUs before you buy (Incase if you need to buy).
