I have a gtx650. i heard that i cannot sli this product with another 650. So i was wondering if i instead should get an Avermedia Livegamer HD Capture Card. i get good fps as it is livestreaming with my 650 but there are occasional frame drops and lag. should i get the live gamer or should i just in general get a new graphics card like the gtx760. what would be the best bang for my buck?
i use OBS (Open broadcast software) to broadcast/livestream.

Your graphics card will do well with rendering what you're displaying on your monitor, but majority of live streaming goes onto your CPU. If you are happy with the graphics performance of your PC, but want smoother gameplay while streaming, you would definitely be better off getting a capture card.

but when i use obs, the video adapter uses a certain gpu. are you sure it mostly runs off a cpu? the advanced settings do rely on the cpu. but isnt the gpu play a key role in livestreaming.

It does play a role, but definitely not a major role. All your GPU needs to do is render the graphics that are being displayed, the rest is up to the rest of your system to store, compress, encode etc the video to be streamed out. Take a random system for example with an i5 and gtx 780, and an i7 with the same GPU, the i7 system will be able to perform much better due to the hyper threading feature of the i7s, but if you take the i5 and add a capture card to it, it will put all that stress of streaming, encoding etc onto the capture card itself and off of the CPU giving you much better performance during streaming even with a lower end GPU.

so i should get an i7 cpu and keep my current gpu? or should i just get a capture card and keep my current gpu. im looking for the most bang for my buck. the capture card is $170 yet the cpu *intel core i7 is around $300.
