Hello - re your question about Chip speed vis a vis on board graphics and mother board performance - there's is not an easy answer to this one - If you are going to store, view and manipulate photos, the number crunching performance of the processor and the amount of avalable RAM on the PC are limiting factors - On a portable PC with on board graphics; the video card may share some of the available RAM and if you are using/going to use, Windows VISTA there are apparently some performance issues with the 915 chip set, commonly found on less expensive portables - I cannot advertise but I suggest that you search for the on line review sections for the popular PC Mags. For the record I'm using a 2 YO Win XP portable PC with a GE Go 6800 Graphics card ( with 256 MB Video RAM) and 3 GB of Sys Ram, with an old P4 Pentium 3.4 Mhz Processor ,Intel 915 Chipset and two 80 GB disks - you will get as good, if not better now, for about £500 - . I find that its all I need - Good luck in Searching
