If you want to match the i5 or i7 as the processor of the computer, the price is more than 6000 8000

In fact, running a software like CAD,Protel or something like that is not too demanding for the computer,i3It's basically enough,It's a little worse if you want to have some functions of a good stand-alone.,Online games are basically not a problem.。 Here are my recommendations, you can choose according to your needs:

Lenovo IdeaPad Y460N-IFI (Gray) ,i5-460M(,2G RAM (up to 8G),500G HDD,14 inches,Integrated graphics + independent GPU,Optimus dual graphics card switchNVIDIA GeForce GT 425M,(1G independent GPU,128Bit,96 stream processors) 5300 or so。

Lenovo Y460N-IFI(H) (Gray), Intel Core i5-480M (Turbo Frequency to, 2G memory (up to 8G), if you use it for games, you can add it to 4G, no matter how much it may be, the utilization rate is not high, 500G 7200 rpm SATA disk, integrated display + independent display, Optimus dual graphics card switching, NVIDIA GeForce GT 425M, 1G independent display, 96 stream processors, 4 interfaces. Around 5500.

Lenovo IdeaPad Y460N-ith (Ash) (ATU), Intel Core i3-380M (, 2G RAM (up to 4G), 500G HDD, Integrated Graphics + Independent Graphics, Optimus Dual Graphics SwitchNVIDIA GeForce GT 425M (1G Independent Graphics, 128Bit, 96 Stream Processors) 4800 or so.

Lenovo IdeaPad Z460A-ITH(AT) (Cool Black), 14-inch, i3-380M processor (, 2G RAM, 500G 5400 rpm HDD, NVIDIA GeForce 310M, 512M GPU, 64bit, 16 stream processor, 4100 or so.

It's best to assemble this according to your needs, so that you have more spectrum in your heart, and you don't have to ask for someone next time.

The notebook can't just look at i5 or i7, the suffix of the CPU is different, which means that the parameter performance of the CPU is also different.

For example, i56300HQ and i7

6500u，i5

The 6300HQ is a standard voltage version with four cores and four threads, and the i76500U is a low-voltage version with two cores and four threads, so that the performance of the i5 with HQ is stronger than that of the i7 with U.

There are many reasons for this.

First of all, the brands are different,** Different,For example, Lenovo HP Dell and other first-line brands are much more expensive than Shenzhou computers under the same configuration,Of coursei5It's nothing more expensive than i7。 Computers are not only based on the processor, but also hard disks (solid-state drives are much more expensive than mechanical hard drives), and screens (IPS high-resolution screens are much more expensive than TN screens) and so on.

In addition, the i series processor is divided into several versions, low-voltage version, desktop version, etc., the low-voltage version focuses on power consumption and low performance, so you can't compare the desktop version i5 and the low-voltage version i7.

I'm using my own configuration! i7 3770 2050 8G RAM 350 Ӱ GTX670 3200 HDD 1T820 Motherboard 560 Power Supply 540 Friends Say My Motherboard Is Too Shabby, Others Look at Your Own Matching....It's great to work that way!

I'm dizzy i7 and i5 are not a grade that can't be compared, and the price will be far behind. i7 is all 4-core by default. Only a small number of them have dual-cores.
