Recently prepared to replace the notebook, the budget is around 10K, after some "exploration" on the Internet, the mind has preliminary results, but in several alternative brands and models, the future of Human (Terrans Force) 4 models made me difficult, I do not know exactly which one to choose. Each of the 4 models is:X611 970M 47sh2, T5 970M 47sh2,T5 970M 47sh3AndT5 970M 47sh4。 Some of the important parameters of the difference are as follows: The price of these computers is not small, configuration is similar, for example, the graphics card model is the same, but there are differences between the CPU model is similar. It can be said that there are pros and cons between them, I think for a long time it is difficult to decide. Finally, I brainwave, why not use math to quantify the parameters and help me make the final decision? So I first assign a weight to each parameter according to the importance in my mind: Price: 0.2cpu:2.5Memory: 2.5hard drive: 1.5Optical drive: 1 resolution: 0.5 video Memory: 1 Battery: 0.5 Weight: 0.3 Total is divided into 10 points. CPU, memory, and hard disk are the top 3 parameters for me, and the other is relatively less important. (The graphics card priority is also high, you understand, but these computer graphics card is the same, so omitted a) weight has, the following is the score. My strategy is for each parameter, the configuration of the worst 0 points, the highest of 10 points, the medium 5 points. Here are the scores: Finally, according to the weight of each model of the final score, as follows: X611 970M 47sh2:2.5t5 970M 47sh3:4.8t5 970M 47sh4:6.9t5 970M 47sh2:3 According to the result, obviously I should The choice isT5 970M 47sh4。
