Some previous laptop discusstions below, for comparison
Also for comparison, go to the CS5 Benchmark http://ppbm5.com/ to see laptop results (I think you may select by laptop)
As for Win8... you might want to see if Win7 is available instead... Win8 comments I've seen so far are somewhat mixed, with the main problems being the "usual" lag of software and hardware updates that happens with every new version of Windows
Otherwise, I don't see any large problems with that laptop (Harm may come along with a different opinion)
Laptop Video Editing PC http://forums.adobe.com/thread/1069742
Second John's opinion about the laptop. Looks good. But with a completely new system I would go for Win8, even though not all drivers, system software and utilities are available yet. They are expected in the next couple of weeks however and then it beats reformatting and a new install.
Why so eager with Win 8? What's the rush? Any advantages with video editing?
I never trust 'upgrading' an OS. A new OS requires a fresh format and a whole new install. The consequence is that your volume ID changes and that means getting a new activation code for some programs. A new OS means getting used to it and that applies to the 'Apps' interface of Win8 in particular. Before you have tuned your new system, the currently missing drivers may be shipping and that problem is solved.
No, Win8 does not perform better than Win7 for editing, it starts a bit faster, but that is about all the performance differnce you will see.
All things considerd, I think when you have Win7, wait a bit to learn from those who went ahead, but if you need to get a new system, then by all means, go for Win8. On my 'old' system, Harm's Beast, I use Win7, it is only on the new system, Harm's Monster' that I use Win8.
Thanks guys. Its always nice just to get a bit of reassurance before dropping 2k on a system.
