Rendering hardware options

Nearly all my work at present consists of rendering HD-recorded living history interviews for storage on Blu-ray M-discs. I have settled on the Sony AVC 1920x1080 60i with audio separately rendered to AC-3 to optimize quality with file size.
I was just watching some tips on Derek Moran's site, one of which discusses improving rendering times. I had never looked at this, having learned that my graphics card, a Radeon 6450, was not CUDA compatible. I assumed that I had to use the CPU ( i5 2400) to render. He shows where to look for options: after selecting a rendering template, Customize/System/Check GPU. In my case, this displays "Open CL available." Also, on the Video tab, the two Intel Quick Sync options are available under Encoding.
Is selecting a matter of pure trial and error, or am I likely to be able to use one of these to decrease rendering time? Should I just take a short video -- say, 10 minutes -- and time with CPU only, Open CL and Quick Sync Quality to see which is fastest? Are there other considerations I should be taking into account?

Hi Ulodesk,

I think the i5/2400 has Intel Quick Sync capability, so that is an option as well as OpenCL. If it were me, I would do the comparison test. Then you know for sure based on your system setup. Also I would make sure I was getting the fastest playback during preview, check GPU acceleration of video processing: 'for the your graphics card', and have the Dynamic RAM preview max in around '200' when rendering.

Best Regards.......George

It's a very confusing world is Software with all the Graphics cards and their boasts.
It's too much for me so my next PC will have a decent Processor, multi-core ( perhaps six by the time I get it), with as good a graphics card I can afford, nothing too fancy but with at least 2G of memory included.
Trying to fathom SMS and using graphics Card is just too difficult. You'd think the makers would include a line "Suitable for...." and maybe Sony software would suggest suitable cards (( Although these change numbers for each Country, I expect )).

By increasing processing-power the render-times should be reasonably quick . . . and that's all one can expect.

Pity it's not obvious ( to me anyway.).

Maybe I'll try out that Website( thanks), for greater insight, too.

EDIT ( APRIL 2016 ) -
I see Gigabyte NVIDIA GTX 750 Ti WindForce2 OC 4 GB Graphics Card at £100-ish
and wonder if anyone here has experience of this for Rendering....?
With two fans it suggests it will need a PSU up-date - and 4G looks good for the money.
Oddly 800-series appears to be missing, as numbers jump to 900's with prices almost doubling.
