OS is Windows 8- 64bits.

Other HW info:

Chipset H67

Intel Core i7 2600/ 3,4 GHz (four cores - 8 threads)

Frontal bus DMI transfer rates: 2.5 GT/s

The technical info for transfer rates supplied by specialists (Intel does
not provide much information about its chipset, as far as I know) is a bit
confusing. I am posting this info from third parties in case it is of any
use for others.

These third parties say:
_________________________

"So the i7 is 2.66GHz clock speed, 4.8 GT/s per second, and uses the QPI
interface which transfers up to 25.6 GB/s of data.

While the i5 has the same 2.66 GHz clock speed, it transfers 2.5 GT/s and
the DMI interface can handle less than half the data across the motherboard.

Amazingly, the 2.66GHz 2.5GTs DMI i5 is considered noticeably faster than
the top of the line Core 2 Quad 9650 which has 12MB cache, 3.0GHz clock
speed and a 1333 bus speed (FSB)."

Which suggests that my Intel Core i7 2600/ 3,4 GHz (four cores - 8 threads)
would support the 6GB.

Thanks very much to everybody. Your remarks are going to be useful.

Likely replacing your hard drive with a SSD will have no effect on the
performance of Mathematica. Where it should improve performance is cases
where Mathematica needs to read/write data to the hard drive/SSD. I would
guess for most of what you do Mathematica performance it bound by CPU and
memory rather than I/O.

Also, you should pay attention to other parts of your system.
For example, you cannot take advantage of the greater though put of a SSD
that supports transfer rates of 6Gb/s if your system bus is limited to
transfer rates of say 3Gb/s.
