Hello, I am seeking some advice from the good folks on this forum.Current hardware config:Core 2 Duo E66002 Gb Ram7900GT Vid card250 Gb WD SATAII 16Mb HD (XP and the rest s'ware)74 Gb Raptor SATA (dedicated to FS9)I am very happy with this config and FS9As an interim step before going Vista, new vid card, DX10 etc., I would like to bring in FSX and run concurrently on the above system.It is my intention to run another HD dedicated to FSX, possibly another 250 Gb SATAII (because I have one!)OK my questions are:-1. Would I have any conflicts between either FS with this setup?2. Is there a better way? Yep, I could partition the Raptor but would prefer to leave it just now.It is essential for me to keep the performance of FS9 up to what it is currently running at. I want to 'play around' with FSX so peak performace with 'X' is not an issue.Any assistance/advice, would be appreciated.RegardsJock

No they do not conflict at all, the folder structure keeps separate cfg files..you can even install them on the same drive without the need to partition.I run both versions (FS9 & FSX) off the one XP hard-drive..I use a second hard-drive for Vista (Dual-boot PC) and have a second instance of FSX on that hard-drive but hardly ever use it as I'm more than happy with XP at the moment but it's there waiting for DX10!!RegardsJim
