I recently started building a new system, and the HDD I ordered is 5400RPM, to save a few bucks ya' know. Now, my friends just wouldn't give me a break about it, assaulting me with cheap insults (derived from envy of my new system, I can assume) about how stupid I was to not go with a 7200RPM drive.
But alas, they could only offer me criticism. What I would really like to know though, is how noticable a difference can be seen with a faster RPM drive?
Well, not really...I have no numbers, but I do agree with your friend, it had been wiser to pay a few extra dollars for a 7200 rpm drive.
They are faster, no doubt about that. I have a 7200rpm drive and compared to my old 5400 drive, it´s a lot faster.

7200rpm is a lot faster. I have 2 WD drive, both are ATA33, one is 5400rpm, one is 7200rpm. From the benchmark, it has about 30% diff
All other things being equal a 7200 RMP drive will be faster then a 5400 RPM. There are two things affected by the RPM of a drive.
Seek time, on avarage a 7200 rpm drive will spend less time waiting for the head to reach the sector on the disk it needs to read.
Transfer rate, the speed data passes the read head. There are two factors that effect this, the RPM of the drive and the density of the data on the disk.
If you have two 20 Gb/platter drives a 7200 will beat a 5400. If you have a new 20 Gb/platter 5400 RPM drive and an old 1Gb/platter 7200 RPM drive the 5400 RPM drive will win by a large margen, transfer rate could be 3 or 4 times that of old drive.
