How big of a difference between 6 gb/s and 3 gb/s?

Just got an SSD, and so far, I've noticed a noticeable speed increase over my 7200 RPM HDD, but it's not quite as big as I was expecting. I don't know if I just had my hopes to high, or is my 3 Gb/s ports on my cheapo motherboard limiting the speeds of my SSD?

Here's a screenshot of my tested SSD speeds.

Also, my SSD is this one: http://www.amazon.com/Kingston-Digital-2-5-Inch-SV300S37A-120G/dp/B00A1ZTZOG/ref=sr_1_2?ie=UTF8&qid=1417581681&sr=8-2&keywords=Kingston

The 120 GB model. Thanks!

Ok, that puts my mind at ease. I have a new motherboard ready to go (don't worry, i tested to make sure it works because of loss of warranty while waiting) when I get enough money for an i5.

saddly due to other lmitations on the controllers for the SSD drives it does double the speed that you see it is only around 1.5x the speed that is on the drives with the best drives capping out at 550MB/s read and 200MB/s write. Now if you are a real speed hawk you could try SAS 12Gb/s or SATA M.2 as the SSDs for them get upto 1GB/s reads and around 800MB/s~900MB/s writes just they will require a new drive and a PCI express add on card for the connector.
