Ask the computer hardware experts to come in and help me compare

The question of dual-core vs quad-core has been debated for a long time I myself have dual-core and quad-core and quad-core and eight-threaded i7 My opinion is:

If you are mainly applying some multi-** applications and data throughput, then the quad-core still has obvious advantages You use Q6600 compression** and e8200 compression** Obviously, Q6600 comes faster Because now the compression** software is optimized for multi-core.

But if you're just gaming, or ordinary applications, surfing the Internet, and working together, it's better to have dual cores, because quad-cores can't play at all, and games are still more frequent than cores.

Looking at it now, it seems to be very clear that the advantages of multiple cores can only be reflected in the software optimized for multiple cores, but most of such software is concentrated in multi-** or data processing software, and there are still not many applications, which are of course dual-core advantages at present.

But in the future, the optimization of multi-core and multi-threading is the inevitable result of my study of computers, and the main focus is on language, and now I am studying the clever scheduling problem of multi-core and multi-threading, but if you buy a CPU, it will be eliminated in 2 or 3 years, and it is hard to say how long the "future" is.

Based on the above, I still think that you buy a dual-core good PS E8400 E0 is very overclocked and has perfect performance for normal use.

Intel Core 2 Duo E8400 is enough, with or without buying quad cores, 333 external frequency, 3G main frequency, the speed is strong enough.

Of course, it's E8400, cost-effective, manufacturer, all aspects are OK

It's up to you how you play

Game E8400 is enough.

It's better to work on the operation or quad-core.

Hehe, the easiest way is to format it in its entirety, but the information is important.

Teach you a way to see if there is a virus, after you occasionally restart successfully, you must see which programs are wrong in your task manager, and check and kill them all after the end, for low configurations, you can use eset node32, the antivirus effect is good. Common processes and their meanings are available on the Internet, and you can compare them, and end the process if they are suspicious, hoping to help you.

I've encountered your situation.,I've also redone the system.,But I still feel like there's a problem.,The viruses are all fine.,Not necessarily in the C drive.,Redo the other disks of the system haven't moved.,So I suspect that the virus should be on other disks.,I updated the anti-virus software.,Full anti-virus.,Now it's okay.,Or you try it too.。

The virus cannot be killed by reloading alone, you need to boot and hold F8, and then enter the safe mode to carry out a full antivirus.

Another: Recommend the free Chinese version of the antivirus software, which is completely sufficient.

Go without saying. It's poisoned, although you reinstalled the system, if the poison is not in the C drive. Then you run the toxic file, which in turn poisons the computer. It's best to format everything inside. Redo the computer system. Instead of reloading.
