It's hard to tell with the information you give in the thread; as it does not tell anything about why the load is so high, it could be that tweaking the vps might already fix your issue or that the IO load is to high, making processes to queue up.
First glance at the numbers would say, yes, you may want to look at a dedicated; the question would just be, what kind of specs are needed.
So, that only accounts for about 50% CPU usage. I am not getting how you are sitting at a load of 8 if you are not sitting at 100% CPU usage. Can you post the a snapshot of the output from top? That might help.

If you are still getting the same result then maybe you should consider a Dedicated.
