Cloning Harddrives

[Plugpennyshadow]

I am currently running two 300gig Western Digital 7200rpm SATA drives.  One has windows XP Pro on it.  This drive has apprx. 117gigs used what with having games, music, movies and such on it as well as XP.

The other drive is used exclusively for storage and onboard backup of the primary drive.  I use XP's backup utility to backup certain folders once a week.

Another 500gig WD IDE drive is used in an external enclosure to backup the entire "My Documents" folders from each puter in the house (5) monthly.  I place this drive in the fire-proof gun safe.

I would like to change to a different configuration:

I want to get two 150gig Raptor 10,000s.  Loading XP Pro, certain other needed programs (MS Works Suite, O&O Defrag, OneCare...etc)  and FSX only on one drive.  The other Raptor would be for onboard, ready access of music, movies and such.

One of the older 7200rpm SATAs will go to onboard backup storage with the other going in a eSATA enclosure for the safe.

My question of the distinguished panel is:
Will I see enough of a performance increase in both general XP and FSX to justify the expense?  Raptor 150s are aprx. $175 US.

Thanks.

And I want to clone my current windows harddrive after purchase of the Raptors.  After some cleanup, of course.  Could someone recommend a prog to clone a drive?

Really, I am looking to max out the performance on my rig the the extent I am able.  I have gotten some advice about the hardware upgrade listed.  Wanted more input before took the plunge.
