Could anyone tell me how much better the Fusion Harddrives are in comparison to the Serial ATA as i am buying an iMac soon and i need to know is it really worth the extra cash?

Physically, a Fusion drive is 2 drives: an SSD and an HDD. OS X treats them as one drive but puts all your most frequently-accessed files on the SSD. SSDs are MUCH faster than HDDs, so for the most part, you will see much less lag related to accessing files, booting up, etc. I have a 2010 iMac that I added an SSD to in place of the DVD drive and still have a larger HDD in place. I can tell you I'll never go back to an HDD-only setup. It is just sick how much faster apps seem to pop now. Anything CPU-intensive will not be faster, but any lags you may experience from data being written to a drive and read from the drive will be dramatically reduced.
Please verify and include the exact model/year of your Mac and OS X version number (available from "About This Mac", then "More Info" on the Apple menu).

I have not conducted "timed tests" but is clearly much faster than my previous Serial ATA.
The drive is really quiet (less mechancal accessing), my computer is running cooler, and the "file management" intelligence implentended on the Fusion Drive is absolutely seamless.
