I am looking to upgrade to a new card for my video editing workstation and I am stuck between hunting out a second hand 1GB GTX 285 on eBay (which is listed as fully supporting the mercury playback engine in premiere CS5) and a new GTX 460 which will support the mercury engine with a simple text document change. If anyone has experience of using either for video editing (particularly Adobe Premiere Pro CS5) It would be great to know how you have got on. I can get both cards for around £150 here in the UK, any advice would be greatly appreciated
