This is an entry-level professional graphics card. Other configurations are similar to ThinkPad E430-3254 1G0 (Core i5-32 102G 500g Rambo GT 6352G camera Bluetooth Win8)3699 yuan, but the price is about 1400 yuan.
If you can't buy a notebook with a professional graphics card, you should also buy a notebook with good graphics processing ability. The Acer notebook you chose, the graphics card is GT7 10M, and ASUS is GT6 10M, all of which are low-end graphics cards, so you can't even play games, let alone three-dimensional images.
Relatively speaking, ThinkPad E430-3254 1G0 (Core i5-32 102g 500g Lambo GT 6352g camera Bluetooth WIN8) has the highest graphics card configuration, with RMB 3,699, which is the best choice among the seven notebooks.
Generally, the CPU of a notebook with a size of about 4000 should be selected in the i5 generation. The higher the graphics card, the better, and the larger the memory, the better. ：

Price killer Shenzhou Jingdun K480N-i7 D2, CPU up to i73 generation! Graphics card reaches GT640M!
The CPU speed of HP's two machines is 0. 1G, and the hard disk is 250G, so the price is higher than that of 450 yuan, so it doesn't make much sense, or is the former cost-effective? . Dell, Acer and Toshiba don't have HP g6-2332tx(D9G72PA), which is cost-effective.
ThinkPad E430-3254 1G0's graphics card GT635M/2GB memory is equal to HP g6-2332tx(D9G72PA)' s graphics card HD7670M/2GB memory, depending on personal brand recognition and appearance preference.
Buying a notebook depends not only on the configuration and appearance, but also on after-sales service. After-sales service Lenovo, Dell and HP all have a good reputation, and other brands are similar.
The model is selected, and buying is also a key link, more important! If you are fooled by profiteers, you will not only do your homework for nothing, but also lose money directly!
When you buy a notebook in the computer city, you must stick to the model you choose and bargain. If you meet profiteers, they will make you wait for a while, and they will pick up the goods. When you are impatient to ask again and again, they will say that the model you want is gone, or they will recommend you a model with better cost performance. This is the beginning of their fooling you! The most common thing is to make a fuss about CPU, such as changing intel's CPU to AMD's CPU model. Seriously, quad-core AMD's CPU is better than dual-core four-thread intel's fake quad-core i5. You should know that AMD's quad-core CPU notebook is also cheaper than Intel's i5 CPU notebook 1000 yuan! There is also the replacement of i3 and i5 generation CPU by i3 and i5 generation CPU, and the price difference is several hundred yuan. You should know that the second generation of i5 can only be ranked in the same grade as the third generation of i3, and if it is compared with the third generation of i5, it will be a grade away! The difference is also several hundred yuan. Furthermore, there are graphics cards. Generally speaking, a graphics card has a price difference of several hundred yuan. For example, although there is a word difference between gt640m and gt650m, there is a price difference above 500 yuan. And gt640m and gt640m le. The former has 128 stream processors, while the latter has only 96! A quarter less! The price difference and performance difference are not small! And whether the video memory of the graphics card is 1GB or 2GB is the difference! There is also a big fuss about the stream processor of A card and the stream processor of N card. In fact, there is a problem of calling the stream processor. The stream processor of A card needs to call five stream processors at a time to complete an image processing instruction, while the stream processor of N card only needs one stream processor to complete an image processing instruction, so the five stream processors of A card are only equivalent to 1 stream processors of N card, and the 480 stream processors of A card are the same level as the 96 stream processors of N card! For example, HP has some hd7670m graphics cards with one card. Originally, this graphics card was only equivalent to gt635m, but the number of stream processors in one card is 480, which seems to be very high, but in fact it is only equivalent to 96 stream processors in N card. If profiteers say that A card has 480 stream processors and N card has only 96 stream processors, many people can be fooled! When the seller says that the model you want is out of stock, you can only leave a sentence "I'll find another one if it's out of stock". When you negotiate the price, the model you choose is still in stock, you know!
And the Dell model. Dell sold in Computer City is an order from a big customer, and the notebook configuration similar to Dell official website model will be much worse! CPU and graphics card are the most fiddling places! For example, i7 II replaces i7 III. You should know that the test value of i7 II is basically the same as that of i5 III, and it is a whole grade worse than that of i7 III, at least there is a price difference in 500 yuan! Graphics cards are also the goal of slimming, GT630M, GT620M, GT6 10M, and each slimming file has a price difference of several hundred yuan! The only place to buy Dell is Dell official website! Other channels are castrated versions of the same paragraph in official website! ! ! One thing is certain, that is, the Dell models sold in the market must not be found in official website, nor can they be found in configuration! But this is not a fake Dell, but a model customized from Dell by agents designated by JD.COM, Suning or some industries.
But big sellers of brands like JD.COM and Suning, Lenovo and Hewlett-Packard will not buy castrated versions as long as they have the same models as Lenovo and Hewlett-Packard official website!
