Recommended Video Capture Software?

It does not matter what software you are using - they all use same 3rd party codecs to encode the video.
Huffyuv/lagarith - lossless codecs (huge file size), very little cpu usage.
Mjpeg/RTV1 - lossy, high file size codecs, light cpu usage.
x264 - lossy, smallest file, huge cpu usage.
H264 (hardware) - no cpu usage, uses videocard to encode the video (intel/amd/nvidia), small file size. Shadowplay uses H264.
If you have enough disk space (considering 1 minute = 1 gb) - try saving and huffyuv/lagarith or MJPEG/RTV1 and encoding later.
If you do not have enough space - you can try utilizing H264 codec that requires OpenCL (i think your amd hardware should have opencl enabled). I think OBS should have this codec available, and msi afterburner should have it available too in some future.
Also, try reducing game fps to 30 and resolution to 720p - those are specs youtube converts video to anyway, so playing/recording at higher is pointless.

What lxSch says it is golden. You're complaining about CPU time, this is the best method since you do not have an Nvidia card that supports ShadowPlay (There isn't an AMD equiv yet). You could also look into other H264 recorders like what he's mentioned.

I think the problem here is that Shirana is using a Laptop, which typically doesn't have a hard drive capable of writing fast enough for Huffyuv/lagarith not to mention the space requirements. =\

The only thing I can really think of that will work 100% is FRAPs. Once again though, huge file size, the need to encode later, it all gets tiring after a while.
