A good cpu?
Answers:
At this time , speed is no longer an issue. The reason being is that CPU manufacturers have hit a wall in their ability to make even faster CPUs. Reason being is because of the size of the CPU itself. The board they make has gotten so small that the electrical paths are so close together, yet so tiny, they are interfering with each other. A smaller sized CPU would result in a faster performance because the electrons would have travel less distance, but since we are at that wall...no faster CPUs are forthcoming for a while. Reason being is because they just can't get the tiny connections any closer. These connections are a lot smaller than one of your hairs.
CPUs are currently at the end of third generation. I do not know when the Fourth Generation will arrive, but till then the manufacturers are tweaking with what they have now.
That is why you are now seeing dual and quad core CPUs. Just more tweaks to get more performance out of the same older tech to keep sales going until Fourth Gen can arrive.
64 Bit CPUs are out there which do perform much better than 32 bit, but not too much software has been written for 64 Bit CPUs.
So if you are a gamer , best to stay with 32 bit CPUs for now.
Best to get the dual core 32 bits ones with a large Level 1 Cache.
This Level 1 Cache is a memory storage for the CPU on frequently used commands. It is extremely high speed because it sits on the CPU thus not having to fetch those store commands from main memory which is about 1000 times slower . Level 1 Cache is also expensive.
Bus speed is also something to consider. The faster the better. Intel's is faster, but AMD processors tend to be faster (and use more electricity).
On the other side Intel's faster bus has bugs in it at this time and people are having to reduce bus speeds on their mother boards because of those bugs.
General rule is that if it costs more, it performs better.
Speed. Obvious.
speed and a large hardrive, propaply 80gb+
The things you want to look at are Brand, Speed, Bus Speed, and Memory any CPU is only as efficent as the slowest part, the faster the Bus Speed the faster your memory and proseccor can "talk" to everything else in your system
That kind of depends on the CPU. Recently Intel has come out with it Core Duo 2 which has a relatively low processing speed (as in it only goes at about 2.00 GHz) but can process huge amounts of information. Think of it as a faucet, the wider the faucet, the more water is pushed out, so speed isn't too much of an issue. AMD processors run pretty much the same way, but they have a bit less power.
Aside from AMD and Intel's Core Duo 2, you want the most GHz you can get and as high a Bus speed as possible. Also, look at the socket size, the bigger the number, often the better, but make sure the motherboard you get has that socket size. Example: Socket 478 motherboards DO NOT work with processors with socket size 775.
CPU does not mean computer, it is the abbreviation for central processing unit: the electronic system that performs the basic operations of a computer processor.
If you did actually mean CPU, the three fastest CPU models are made by Intel. For comparing the performance of different CPU models and speeds refer to the graphs on the web pages below.

If you are going to just run Microsoft Office and surf the web, and play music and videos almost any video card will be good enough.
If you will be playing games on your computer the choice you make for your video card will be as important as your CPU choice.

Make sure the new graphics card or graphics adapter is DirectX 10 compatible.
