How to Stream with little lag without another PC

[Dood76]

I want to be able to stream on Twitch with OBS with little lag from frames and ping. I don't want to have to buy another computer. Is there a device (like some sort of capture care) to accomplish this? I am going to stream PC games on my PC.

Here is my current setup:
Motherboard: Asus ROG Maximus V Gene
Graphics Card (GPU): 2x Nvidia GeForce GTX 660 Ti SC/OC (1 EVGA and 1 Asus)
CPU: Intel Core i7 3770k @4.2ghz
Memory (RAM): Corsair Vengeance 16gb @1600mhz
Power Supply (PSU): Corsair TX750m
Chassis/Case: Corsair Carabide 400r
SSD: Samsung 850 Pro 250GB
Mechanical Hard Drive: Seagate Barracuda 1TB
and 1TB Western Digital Caviar Black
CPU Cooler: Corsair H80i
Operating System: Windows 7 Ultimate 64bit

If I am correct, Shadowplay is supported on your system. Nvidia Shadowplay supports directly streaming to Twitch and has great quality, 60fps support, and I found less than a 10% fps hit, if even that.

I'm confused as to what the problem is. You most definitely have the hardware to stream. If you're inquiring about dedicated streaming PC's in a setup like GoldGlove has, although they are useful, they aren't completely necessary for streaming.

The one key factor isn't hardware, it's your Internet UP speed. Decent Up is needed for streaming.
