560m would be sweet for cuda
I guess 1 thing to look at is if you can use extended cell battery packs. I tripple boot alot, winxp for 32 bit apps and win 7 ulti for 64bit and throw linux or osx on just for kicks. I have found running atleast daul boot winxp 32 and win 7 64bit extreamly useful, as old apps can be hell under win7 64bit even using compat mode and then some apps really need 64bit (illegal downloaded adobe ones
) So check that you get a win 7 disc with your notebook so you can reformat and partion adding xp then win 7, or a bootloader if your techy
Other aspects are how much of a beatting it can take, you don't want something to fragil. Also if your not doing your image editing on it then save some money and don't go all out on an i7 and dedi vid, but if you are these help a ton
