I have a reference GTX 960 2GB in my system right now, and it works fine, but I'd like to upgrade.
Would 2 GTX 770's in SLI bottleneck and would it be worth it?
Here are my current PC specs:
Intel Core i5-4460 @ 3.2GHz
8GB AMD Radeon R9 Gamer Series RAM (1x8GB)
Reference Nvidia GeForce GTX 960 2GB
Gigabyte GA-B85-HD3 Motherboard
WD Caviar Blue 1TB HDD

EDIT: Forgot to include that my power supply is 350W. I'm going to upgrade it when I can.
And this is also a pre-built system.

EDIT #2: Forgot to check, but motherboard doesn't support SLI.
 
Solution
Motherboard doesn't support SLI, and "when I can" wouldn't cut it on the PSU the system would never work with such a weak PSU.

Don't waste the money.
