4 GB ram is definitely a massive bottleneck. If you stick 8 GB in that machine it will load things a lot faster, as 4 GB is horribly memory starved, and instead of just reading from disk, it will be paging things in memory out to disk at the same time to fit new stuff in.

16 GB is even better, but the big big jump is from 4 GB to 8 GB.

Won't do much for graphics speed though.

SSD will of course help loading times as well, but going from 4-8 GB is very cheap and well worth it.

thanks I got 8gb ram but now the problem is getting in my computer. Thank you.
