The only problem with that is, even though P4's overclock pretty good, your NOT going to get a 1.9 GHz to 3 GHz without some sort of major cooling. Sure, you may get it to run pretty fast, but then don't be surprized if your system locks up or your cpu stops working after a couple of months. Better to spend the little extra money and buy the faster cpu, get the extra speed AND stablility.
You will probably get 2.5 GHz MAX with that 1.9 GHz.
Not sure if you have some great deal on 1.9 cpu but just to break it down:
from pricewatch:
1.9 GHz P4 Northwood: $140 which you MIGHT be able to get to 2.5 GHz
or
2.4 GHz P4 Northwood: $160 (that's only $20 more for this faster cpu)
or
2.53 GHz P4 Northwood: $180 (only $40 more and still has it's warranty).
Good luck
