Upgrade advice please!

[Guest]

So I bought an Asus PC and monitor setup last year mainly to run FSX and the usual racing games. I upgraded the integrated graphics card to a GeForce GT 730 (noisy) but now I would like a triple screen setup.

So what are my best graphics card options for under 200 quid? Could I install two more GT 730's (50 quid each for the new silent ones) or is there a single card I should get?

Thanks in advance, newbie.

Can you even use SLI on 730?
I think a 960TI Is the least you want from triple monitor gaming.
Even then the performance won't be great on 5760x1080
