pls suggest me to chose which processor

I wonder if you'll still even find a regular Pentium 4 at this time. Even Celerons now seem all on the basis of Dual Cores. Anyway, it really depends on what you may want to do and what other equipment you'll have to back that up. After all, a computer isn't -just- the CPU. If you really want to do basic home stuff and do some simple web browsing, the P4, even the Atom may do... I'd suggest 3 or 4GB RAM to go along with it too. If you're planning on gaming though, might want to look at that Core 2 Duo. I actually have all 3 of these processors at the moment. The P4 is my every day machine, it's what I use for most tasks, web surfing, etcetera and it fits very well for that job since 4GBs allow me to turn off Windows' virtual memory and let things run a bit more smoothly. The Atom is of my Eee PC, thus it's meant to be a mobile unit for little things... long battery life and access to simple things like word processing and so. I wouldn't even use it to play except the most basic of games. The Core 2 Duo, well, sometimes I just have applications that are in greater need of processing power like compressions based on more complex algorithms, video encoding, etcetera, and of course playing games. Most new games these days are made to make use of multi-core technology, so you can have a lot more horse power in a dual core chip, not to mention with some which overclocking capability is quite good. I have a E5300, 2.6GHz by default per core, it's running easily at 3.6GHz, meaning a total of 7.2GHz (My P4 is only 3GHz). So it depends what you can afford and what you really want to do with it. I wouldn't bother with the Atom though unless you really want a portable computer.

Hm, do you mean a laptop or a desktop one?? Regular Pentium processor is not available for laptop nowadays. If you only need it to browse the net and do home purpose (I assume only using regular office like words, excel, and power point) then buy a netbook (which using atom processor) since it's cheaper and smaller and more flexible. If you want to do more like editing picture, editing video, playing games, etc, consider buying a core 2 duo processor laptop. If you are buying a desktop computer, again, if you only use it for home purpose then buy an atom processor desktop computer. It is cheaper, smaller, more efficient (use less than 300 Watt electricity). If you want to do more, consider buying a dual core, or even quad core processor (AMD Phenom, Intel Quad Core, Intel E Series, etc) or if you have more budget, you might be interested to use intel i7 processor.

depends on your needs heavy user ,go for advanced like Intel atom low user,go for core2duo or p4 choose processing speed more than 2.5 ghz which gives you a smooth control on system and also the ram .

Intel Atom processors are intended for mobile computers and mobile phones. They are slow, they can't load heavy apps like new PC games and work with operating systems like Vista. They are good for mobile machines beacause they use really small amount of energy and make the battery lasts really longer. Atom is not a good choise for desctop computer at all... Intel Pentium 4 is an old processor family so I don't know if you could get any of them these days... Intel Core 2 Duo are one of the newer processor families on the market - they are fast because every of them works almost like 2 single core processors. Core 2 Duo have a lot of cash - at least 1mb each core. If you are looking for not so expensive processor look for "Dual core" processors made in 2006-2007 i mean the E**** processors like E2200 and above.

If you just want to surf the net and work on documents and play flash games atom will be the best choice because It is less expensive than core2duo and it produces less heat than p4. p4 is a good processor but it consumes more electricity and it heats easily making it prone to overheating. core2duo is the best processor among your choices since it is considerably faster than p4 and atom because it uses two processors and it handles games more effectively. I am not telling you to buy a core2duo processor, I am just giving you its advantages. Choosing a processor is dependent on your lifestyle. If you value power saving or if you like to play games.

hi ravich! I'd like to help you, or suggest rather, A core2duo would be the best processor among your choices, but it will actually depend on what you want,. like you if badly needed to have one, but can't afford the latest processor, you could go for intel p4 IF you would only need it to browse(this does not include online games) the net. This should depend on your budget though

If you are going to only browse the net and not play any games, then intel p4 is more than sufficient, that is, if you are able to get one. Intel p4 processor is not available in the market, and even if you are able to find one, most probably it will be a second hand one. The best is to go for a core 2 duo, since it has got a good speed, as well as you will be able to play a lot of good games. I also have a Intel p4 only, which I am thinking of upgrading it to core2 duo shortly.

there is no need to think of intel p4 or atom processors if you can afford core 2 duo,it's the best.Atom generally takes less power, so it can save your money by reducing your electric bills.
