Yes.
Yes, because the computer with a 2.4 GHz dual core works nearly twice as fast than a 2.5 single core.
It depends on what you are going to be doing with the computer. Multi tasking, gaming..exc..
No. A Dual-Core Processor means there are 2 separate cores, each running at 2.8 GHz. The workload is split between the two, giving a combined 5.6 GHz processing power, but they will not work together on the same thing.
Duo Core means that it has DUAL CORES, meaning 2 cores. So if its a 2.0 GHz Duo Core that means that you double that # and you get 4.0 GHz total. Basically the more cores and the higher GHz, the faster the processor is.
2.5 GHz is better than 2.1 GHz. It is because it is the latest processor. It will be faster than 2.1 GHz.
Having more cores on a computer is more useful than haveing slightly more ghz
No, you need a 2.6 ghz dual core, or a quad core to run it at its full potential.
yes the minimum spec is a GHz processor you should be fine.
All CPUs branded "Pentium 4" are single-cored.
The 2.66 Ghz Quad core is the better processor. the quad core has a top manufacture speed "no over clocking" of 10.64 Ghz and the core duo and 6.66 Ghz manufacture speed. UNLESS the core duo has a wopping load of cache speed witch is a hole nothing story
dual core with 2.7 is enough. And you can chooose a better graphics card too. That is better
