Which of the following lenovo laptops to choose?

Question

laptops

Good afternoon! I understand that there are many such questions, I read almost all of them. Characteristics and reviews on the models listed below, also read. Particularly interested in the opinion of people who have these laptops, maybe there are some nuances.
Help me choose a laptop from several proposed models.
Lenovo IdeaPad Z510
LENOVO IdeaPad V580c
LENOVO IdeaPad B5400
Lenovo G505S (embarrassing AMD, maybe in vain?)
Lenovo IdeaPad B590 59381374
I want a matte screen, 15.6 diagonal, WiFi is a must, a 1 TB hard drive is desirable, price up to 30,000 rubles, weight no more than 2 .5 kg.
Tasks for the laptop - surfing the Internet (firefox with many open tabs), working with documents, watching videos, programming in Pascal, Delphi, Haskell and Python (not professional, at the level of a laboratory university). It is planned to study C # and C ++, use MS Visual 2013. It is possible to study databases and work with them, work with VirtualBox, work with wordpress.
Games are not interested, if only something like Zuma and Tetris.
Stationary i3-3225 + 8 GB of RAM + NVIDIA GeForce GTS 450 + SSD + 1TB screw completely suits me (however, I haven’t worked with VirtualBox yet).
It is clear that any of the proposed options suits my needs, but I would like to choose the best option that will last me at least 3 years, preferably 4).
I really like the first option (processor, screw, weight, resolution, appearance), but I want it cheaper. Does it make sense to buy cheaper?
Mac do not offer :)

Answer 1

In my opinion, it is worth choosing between 1 and s percent AMD.
The rest of the processor models are rather weak and will heat up sensitively.
Lenovo with AMD has a "-" in a glossy screen and again, for a successful display of its capacities, heating. (AMD likes it hot). If it costs good cooling, you can write off this minus.
"+" in 2 USB 3.0 connectors (in variant 1 it is one). And RAM on board immediately 8GB.
Lenovo IdeaPad Z510 is perfect for you, minus can only be attributed to 4GB of RAM at the start and you have to upgrade Windows. The model will serve you more than 2 years. If you periodically change the thermal paste, the heating of the laptop will not bother you at all. The video card could probably be better, but for your requests it's not so critical :)

Answer 2

I have a v580c, though a modification with a Core i5, 8 GB of RAM and a GT740M. Now I am writing from him, everything is perfect, he is business class and business class in Africa. Very light for a 15"30', very fast stone for a laptop, very good graphics. And most importantly - a lot of RAM. I took it for 25k. In my opinion, it fit perfectly. A few
words about the CPU: for your tasks, Core i5 with two physical. cores - behind the eyes.Even virtual machines do not heat up so much, if it's some kind of web or network, you can put a cap on 30% of the core and still everything works very quickly - stone fire.
A few words about RAM: yes, everything is bad with virtual machines, but ask yourself - is 4 GB enough? On Windows, I was sorely lacking. Arch in this regard is more stable and, in general, 2 GB is enough for him. But virtual machines were very, very difficult, because it was necessary to make networks, and this is not really my profile ... In general, I had to do halloworlds, but how hard it was to run three pieces of Windows Server 2008. I am silent about a dozen. 8 GB is the minimum required when working with virtual machines.
