Hi, I got three quick questions.

1. can you only use your pci-e x16 slots to make crossfire or SLI?

2. What happend if you put 2 different gpu together?

3. Is 2 vram enough for gaming and future gaming?

The only reason for me to buy a good motherboard is because then i would have enough space to just buy a new graphic card when my graphic card becomes outdated and then I could just put a up-to-date next to it.

1. if you run a gpu on pcie 1 x 4 or 8 you will lose performance
2. totaly different gpus dont work
3. 2x2 more than enough
But you would be better with one single card since you won`t get double performance and you have to pay more for electric bills.
