Last year I upgraded the HDD in my 'old' Core 2 Quad system to an Intel x25-m 160GB SSD and it made more than a significant difference to the Windows 7 load time. Despite some glitches with the drive that have meant a couple of complete wipes and restores from a clone copy during that time to now, I would never go back to an HDD. For the record, the Mobo is an old Asus P5W64 WS from 2006, with 8GB memory DDR2 memory running at PC5300, a Q9770 processor slightly overclocked at 3.3GHz, and two graphics cards, an old X1900 and an old GeForce 8800, CPU and Graphics water cooled. While it would never break any records, it runs very sweetly and is more than able to cope with any of the business loads I put on it, like Excel number crunching, video re-encoding, audio encoding, SETI processing, graphics rendering, etc. I don't doubt for a second though that it would be useless in modern gaming. But that's not what it's for.
