I am looking at 2 second hand cards on my new zealand auction site, similar to ebay. I am looking at a (MSI nVidia N260GTX-2D896-OC 896MB) and a (Gigabyte GV-N26OC-896I) The gigabyte card is more expensive but its the one im leaning toward as I currently have an MSI card and im not pleased with it. I have to run it on the MSI modified forceware drivers and not the standard release forceware from nVidia's site which do seem to offer more performance. I was also looking at a gigabyte GTX275 but the guy has no box for it or receipt so im not sure if thats a safe card to go with and I also heard the 216sp release of the 260s are faster than the 275s anyway. What do I do?
