How much difference does it make on gaming performance of the data fetching rate of internal harddrives?? for example i have a 800 mbps rate hd and the newer ones have 6gbps how much a difference will it make in gaming(provided all other factors are optimum)??

The only time faster hard drive accessing makes a difference is when you actually have to access the hard drive.
That is when
-game loads
-maps load
-you have HUGE textures (Skyrim)
-for some coding error you have to access the hard drive while gaming (rarely but sadly happens e.g Assassins Creed 3 if memory serves well)

But aside from these times (a.i. when all data is already in your memory) the effect is not significant.

it can make a big difference but for gaming you only need about 130MBps to stop texture pop from games that stream there textures rather than buffering them in ram.
6 Gbps = 768 MBps
so thats pretty close to your 800MBps. (notice the uppercase MB it stands for mega bytes, mb stands for mega bits which is 1/8 the size and is not used to calculate drive speeds)

note that mechanical drives are significantly slow compared to ssd. ssd is A LOT faster. i have 2 of them, and it works wonders to the OS and my favorite games (due to limited space)
