I often run a transcoding of HD wtv video files from Media Center to 720p or 400p H.264 mp4's. I'm making use of Intel Quick Sync courtesy of my i5-2500k @ 4.2Ghz, p8z77-v pro and Arcsoft MediaConverter is my tool of choice.

I noticed recently how big of an impact GPU performance can have on this process. I converted a 25 min 1080i wtv clip to 400p H264 and it took 1 min 13 secs for that transcode. When I tried turning off hardware GPU decoding in MediaConverter, that same conversion took 4 min 14 secs! Percentage-wise I was shocked at the difference. My graphics card is an ancient 8600GTS card.

After looking through some reviews I saw that the GT 520 offers insane decoding performance (297 fps for 1080i MPEG2).

My question is, would the $50 upgrade to this card offer a massive performance upgrade to my usual transcoding job? What type of performance benefit could I expect? The rest of my desktop is modern (SSD's, 16GB of RAM,etc.) so this seems like a way to bolster my transcoding performance easily and cheapily. (I'm not looking to upgrade my CPU right now which I know is an obvious upgrade option). Thanks in advance for any comments or suggestions.

Hi raventerp,

I'm amazed to your observation on i5-2500K performance with and without GPU for 1080i video. I would be grateful if you could please share the only decoding performance on Intel HD 3000 for 1080p (preferably or 1080i) H.264 Video Sequence Decode.
Thanks really appreciate your response.
