Swap 5400RPM HDD with 7200RPM HDD?

[ravensfan55]

I have a year old 15' MBP, with a 2.66GHz C2D, 4GB of RAM, and a 320GB 5400RPM drive. I just purchased a 250GB Seagate 7200RPM drive which I use in an external enclosure for my Time Machine. I have no complaints for my computer being terribly slow, but I was wondering if I would get a significant boost from having the 7200RPM drive in my MBP.

Before anyone recommends that I get a SSD, I do plan on buying one once prices keep dropping. Right now $1600 for a 480GB OWC SSD is a little steep for me.

u should see a nice little boost .. i have a 5400rpm drive in my i7 mbp and im probably picking up a 500gb hitachi to replace it with .. prices for ssds are still too high for me
