GPU-acceleration was brand new to Premiere in CS5, and it was limited to just a few Nvidia cards. It took several years to get to the point it's at today. You're using a card that didn't exist back when this software was developed. OpenCL wasn't mature enough back then, which is why the technology was only limited (officially) to a few CUDA cards in the initial release of CS5.For reference, the Mercury Playback Engine doesn't mean GPU-acceleration, it's a marketing term that comprises a few different technologies. Software-only mode can still be fast, especially if you're not working in huge frame sizes or with a lot of effects.GPU-acceleration is much better in almost every case, but if all you're doing is straight cuts with no effects, then you likely won't see much of a speed difference. There's a lot more that needs to be considered when comparing speed (for example, if you're scaling your final output), so it's not so cut and dry.With the card and version of Premiere you have, your only option is Software-Only mode.
