I want to 3 Way SLi/ Crossfire

Hello everyone, been quite some time since I last posted so hope ye're all doing well.

Ok so Im building a new PC, my last one has last me over 6 and a half years but frankly its having trouble running even some F2P games now so its time for a total rebuild.

Heres the Mobo im getting:

ASRock 990FX Extreme4 - Socket AM3+ - ATX

Heres the card I'm thinking of getting and remember ill be buying 3 of them:

EVGA GeForce GTX550Ti FPB - 1GB - PCI-E

Im no novice to building PC's as I've built a fair share of them over the last few years but when it comes to 3-way SLi'ing I only have a brief knowledge.

So I went googling and found out according to a post in some forum last year sometime that there is no such thing as a 3-way SLi bridge and that I should use Single bridge connectors.

Yet I cant seem to find the Single bridge connectors at all. I do however have the Connector for SL'ing two Cards unless that is what is referred to as a single bridge I am unaware. Any help on this topic is appreciated.

Also, I was always an nVidia geek so to speak, havnt changed from them in years. What I do know is that ATi are quite good now as with 7 years ago. Any recommendations on Cards to Crossfire?

Im willing to spend at the most €140, as the PC im building is costing me a lot.

Thanks for reading:major

 

I am no hardware expert. I googled and found these but am not sure if this is what you are looking for.
