2 video cards or one?

Question

Iron

I read that 2 cards are better than one for the same amount ..
There was a question about the tire.
If we take two identical cards with a 256-bit bus, then the total throughput will be 512?
And the question itself is better to take 1 card with a 512-bit bus or 2 cards of 256 each?
+ to 2 cards: more
productive.
more memory.
cheaper.
- will eat more.
+ to the 1st card.
takes up less space.
eats less.
perhaps more productive than 2e.
-xs.
Honestly, I xs, if it sums up, then I wrote everything correctly .. So memory is not so important. The main bus, everything else is 2nd in importance.
Can you put 2 different ones?
For example, one will store, and the second will process .. or is the 1st option better?

Answer 1

It all depends on the games. Some games don't use sli or crossfire well. Read on the forums of the games you are interested in which configuration suits them best.

Answer 2

• increase in games from the 2nd video card is about 20-50% maximum
• you can use a 2nd video card plug to calculate physics in games, you don’t need a cool one there
• if you are for professional tasks, then you need a special video card
