Which one is an expert in computer hardware comes in

1. SLI is not necessary, one depends on your needs! It depends on what specifications of the graphics card SLI you use, all of which are made by advanced gamers and enthusiastic players, and those who can do SLI generally choose the top graphics card to do it, in order to play the game, the most powerful performance, and when playing, the game settings are played to the highest requirements! The monitor is 24 inches or more!

There is also a top graphics card ** in 5000 pieces, than his second point ** in 1999, players do not want to pay 5000 pieces, to achieve or exceed the performance of 5000 graphics cards, after technical analysis, it is found that with 2 graphics cards composed of SLI, the performance exceeds the level of 5000 pieces of a single card, there is a need to choose SLI!

As for which interface you plug in the output, there is no rule, you can do it! Also,Landlord,A card doesn't have only one interface,Generally, mid-to-high-end graphics cards,It's all 2 DVI outputs,Plus another output,Group SLI is at least 4 monitor outputs,Not 2 as you said!

2. Physical acceleration is theoretically very good, and it should have a great role in future games, but, now it basically doesn't have any effect, there are very few games that support physical acceleration, and there are supported games, you don't necessarily play, at present, this is not important, think about it, if it's important, can AMD leave it alone? At the moment, there is no physical acceleration, there is no big difference.

3. The effect of water cooling is definitely a very good effect, but the cost is high, the installation is more troublesome, and it is necessary to pay attention not to leakage; When to add coolant, it depends on the situation, do not need to add frequently, the liquid is not ordinary water, the landlord remembers! The configuration of water cooling is based on a large budget of money, and there is a fever, for the heat dissipation effect and visual effect, there is still very little use, there is no need to pursue this, after all, if you are suitable for the person with the water cooling system, you don't have to ask here, so, I think, you are not that kind of enthusiast :) right?

It is better to build an SLI or crossfire with a low-end graphics card than to buy a mid-to-high-end graphics card with the same **.

If you want to set up a dual-SIM firefight, you need to see if it supports firefights when choosing a graphics card.

If you are not an enthusiast player, you generally don't need a two-card firefight.

The physical acceleration card really makes the display more powerful. But generally you can't use it, how much money do you want to choose a graphics card? Is it more than 2000? Do you have to spend more money than a graphics card to buy an accelerator card?

If you're not an overclocker, there's no need to cool with water...
