How much do good high quality backlinks help your site?
 

Hi,
I have a website with few competitive unoptomized pages. Its just new and has a page rank zero however recently I made links with a good amount of Forums and blogs that are related to my niche with page ranks of between 2 to 6.
How much will this help my website move up in google? I have a feeling it will help a lot could it? Content is all unique as well.
Thanks for any help.
