GTX660 SLI vs GTX780?

[Koulhs98]

Hi

i can't decide which one should i get. I have one GTX660 in my current gaming rig, but for me it isn't powerful enough (getting 35-55fps ultra in bf4) so i wan't something more powerful. I have money to spend around 350€. So should i get one gtx660 more with 190€ or sell my current gtx660 to my friend and get gtx780(499€)?

and if you say i should get gtx780 will it fit in this case

Firstly of all, get a ruler and check the whats the length of your case inside. Check from the pci panel to your hardisk drive cage. if you have atleast 11-12 inches space then the gtx 780 will fit because the dimension of the reference gtx 780 is 10.5 inches.

Get a GTX 780 if you have the money. Its 15-20% more powerful than GTX 660 SLI. just make sure of your PSU is 600w or more, thats 780 minimum PSU requirement.
