Hello everyone,
I was looking to upgrade from my laptop to a gaming desktop.
Im looking for a single monitor build (Dell U2713HM) and i tought about a Gtx 780 SLI classy. Im not planning in any future OC.
Its still a concept so im willing to have some advice about other components, will be like:

Case: Corsair obsidian 750D
MoBo: Asus Z97 A
Cpu: intel I5 4690
Ram: kingston hyperx beast 8gb (2x4) 1600 mhz
Ssd: samsung evo 250gb
Hdd: wd caviar blue 1tb
Psu: dont know
Cpu cooler: be quiet! Dark rock 3
Am i missing anything? Budget is around 2.500€
Im sure this is the right section im new on forum!
Thanks in advice and apologize for my bad grammar!
Josh

Not necessarily useless, but the performance improvement may not be sufficiently large enough to warrant the expense of a second GTX780. That is why I suggest you try one card first.

I have no problem overprovisioning a PSU a bit. Say 20%.
It will run cooler, quieter, and more efficiently in the middle third of it's range.
A PSU will only use the wattage demanded of it, regardless of it's max capability.
That is why I suggested a 850w psu.

Multi monitors are not an issue with a single card, so long as you are gaming on only one.
A second side monitor does not hurt gaming at all.

If you are contemplating gaming on triple 1440P monitors or a 4k...

With your budget, I would get the 4690K instead.
I would start with a simple EVGA GTX780 superclock, one with the titan blower cooler.
That is likely to be plenty for any single monitor.
The blower cooler is more efficient at getting heat out of your case and makes the option of adding another easier from a cooling standpoint. A single GTX780 should have about a 650w psu.
To provide for possible sli, that psu should be 850w.
Buy only a quality psu from Seasonic, xfx, antec or the like.

If you are contemplating gaming on triple 1440P monitors or a 4k monitor, that is a whole different ball game.
For that you will most definitely need dual cards and GTX780ti would be appropriate.
