1. At present, the price of graphics card has skyrocketed e to mining. 970 can sell 1500 +
980 brand is better, and it can add a little, worth about 2000
however, e to the current mine disaster, the price of the video card will drop again, and the price of 980 will drop soon.
2. Taking the Raptor Strix GTX 980 Ti game graphics card as an example, it adopts ASUS directcu III heat pipe direct contact three fan design combined with fan blade shape silent fan design, which can provide large air flow to achieve excellent heat dissipation and strong silent effect. This video card adopts fully automatic process technology and the second generation super alloy power supply design, which can achieve better quality and rability. In addition, GPU tweak II with xsplit gamecaster function enables users to easily adjust performance, stream in real time and record the game. Adopting ASUS directcu III heat pipe direct contact three fan design, equipped with two dedicated 10 mm diameter heat pipes, it can discharge part of the GPU hot air and achieve excellent heat dissipation effect
Proct specifications may vary depending on the country or region. We sincerely suggest that you confirm the specifications of the procts currently on sale with your local distributor or retailer.
3.

In order to provide strong performance and design of air-cooled / water-cooled hybrid cooling game graphics card, Rog Poseidon Poseidon graphics card integrates directcu H2O hybrid cooling technology, which greatly improves the refrigeration performance of air and liquid, and brings better flexibility and freedom of choice

water cooling is a kind of cooling method that many computer enthusiasts often choose in order to improve the overclocking ability and cooling performance of the graphics card, and the configuration and installation of water cooling equipment is relatively expensive and difficult. Poseidon, developed by Rog team, brings directcu H2O hybrid cooling technology to provide better cooling scheme and flexibility for the graphics card, It can effectively rece the GPU temperature by 27 ℃, extend the service life of the graphics card, and enjoy a more stable overclocking experience. Directcu H2O hybrid cooling technology combines vacuum chamber soaking plate, water pipe and standard G1 / 4 & quot; Water cooling head interface, easy to adapt to the existing water cooling equipment, can effectively rece the temperature, bring better cooling effect, and better mute effect

4. It seems that you can't hang up to dig. When you dig, you need to input verification. If you answer the right question, you can dig. If you answer the wrong question, you have to ban mining for half an hour!
5. I think we should choose a suitable game, koala, in which you can find all kinds of mobile games. You can also refer to it later.
6. Let me tell you about an efficient green one, [sun assist 1.02 free version]. There is no virus, no advertising, acceleration is quite fast, I don't know if you like it, anyway, I am very satisfied with it.
7. QT interface development, but I still do not recommend using java to write the client, it is too pit.
8. If you want to realize that both the server and the client can send messages to each other without waiting for the other party to respond, you just need to put the InputStream and the OutputStream in two different threads, that is to say, the receiving stream and the sending stream are monitored and processed by one thread respectively. If you want to achieve regardless of the client server, you can use UDP communication to supplement the answer: if it does not involve mime, just send and receive simple text mail. It will be simpler. Because as you said, the protocol of SMTP and POP3 is text format. After you establish a connection with socket, you read the data line by line just like reading a file, and then analyze the data format according to the protocol. For example, if user is used at the beginning, it may be followed by the user. Is a string parsing and matching process. There seems to be this kind of code on the Internet. Find one to learn by yourself. I've done it on 68K with C before, it's not very difficult. But the code is gone.
9. (1) First, the server starts the monitor program to monitor the specified port, waiting to receive the connection request from the client
(2) the client program starts and requests to connect to the specified port of the server
(3) the server establishes a socket connection with the client after receiving the connection request from the client
(4) after the connection is successful, the client and the server open two streams respectively. The input stream of the client connects to the output stream of the server, and the input stream of the server
connects to the output stream of the client. After the connection is established, the two streams can communicate in two directions
(5) when the communication is finished, the client and server are disconnected.
