Hey Guys,

I am using MSI Z87 G45 motherboard with 3 PCI-E ports x16 - currently have single GXT 780 installed.
I am planning to get another GTX 780 and run it in SLI but have a problem - my current card takes 2,5 slot.
Is it possible to add another card in Port 3 (I don't have enough space to fit it in port 2), so have cards in port 1 and 3 ?
If such combination is possible, will the card run in x8/x8 mode ?

If no, do you recommend to:
- sell the existing card or
- get a different brand with similar clocks (thinner) and try to squize them in ports 1 and 2 ?

Thanks for your help,
Mick

Does this mean 8x 8x ? AND if i put the card from PCI_E5 to PCI_E7 it will run 8x and 4 x ?

Will this bottleneck ?
