OK how about finding few more candidates? (Needs a new topic?)
just change the OP's title, it'll change the incoming replies as well but not the already posted ones.
characteristics of what you should at least aim for:
i5-2410 | reason: to be able to decode the incoming Hi10Ps and lesser hiccups from other programs. it is on-par with the desktop i3-2100T.
GT525M | reason: so long as you'll game @ the resolution of 1360x768 then you should have no problems. it is slightly slower than a desktop GT540.
4GB ram | reason: obviously you don't wanna have so little of ram. as you could pretty much dictate the seller on how much you should have, it shouldn't be a problem.
led backlit | reason: more battery life, thats pretty much it.
9cell battery or more, maybe less | reason: umm, do i really need to say why?
anything else you can consider as a bonus.
oh yea, backlit keyboard! the best bling you can get thats actually useful.
list of models that i found on my area thats mostly below 800$, if not all.
