I've been researching this product and can't decide on which version to buy, 10 or 11. I thought here would be the best place to post my query. I have a Dell XPS710 with an nForce 5 chipset, running WinXPPro Media Center Edition, with a 500Gb SATA drive. It has 2 partitions beside my main "c:" drive, 1 is 32mb (FAT) and one is 4.64GB. I assume one of the partitions is where Dell keeps its recovery files. I've read about some people having issues with nForce chipsets. I've read so much, I can't remember which vesion of ATI the problems came from. Is 10 recommended over 11? I know that 11 is fairly new. For my system, is one recommended over the other? Also, is there an advantage to buying the CD over a download? And, is it recommended to use the Secure Zone? Will both versions of ATI make a copy of the MBR before overwriting it? If there are resulting issues, assuming ATI does copy the MBR, is it easy to restore it? I have read numerous posts in this forum for days and have left myself confused over the versions and issues. I know there is a free trial of 11, but I want to be with a stable product. Any input would be appreciated.
