can you notice the speed difference?

When you use a different GHZ, you'll notice to do any application and transfer data. Usually you took 1 minutes for old computer, and for new computer it can be less than 1 minutes. Try for using much application and you'll know the different if you compared with other computer.

Maybe you are expecting too much improvement in terms of speed? There will certainly be an increase in speed and performance. You might not notice it, but if you use back your old computer, you will feel the difference in terms of response time and better performance overall.

Hi, you can't feel the speed difference by just browsing the sites or by just visualize your screen, that speed difference can only feel by debugging a software program of million lines.

Well, it does make a difference. I had a 1.7 ghz Celeron and then I upgraded to 2.8 Ghz P4. It did make a lot of difference (well the P4 was far better). Everything was faster, including boot up, gaming, AV scanning, and heavy tasks. The only times I didn't notice much difference was when using lighter programs like browser or wordpad.

i handled a cpu 1.6ghz and then i used 2.20ghz i can see the difference in terms of booting up and loading of programs, here in our office almost computers has the same programs installed on it but differ on computer specs.i can see and feel the difference when you browse the net or open programs, obviously the higher cpu speed takes the lead. also depends on what programs are installed on both computers even if you have 2.20ghz cpu but it has lots of programs and startup folder is full compared to the 1.7ghz cpu w/c only has a couple programs, so the latter would load up and open programs faster in an inch of a second compared to the other 2.20ghz cpu.
