I'm going to use it for regular use, MS Word, browsing, watching movies and gaming. I'm not a hardcore gamer but playing games like Portal 2, Guild Wars and some shooters on high is a plus. Im not buying the 27'' because its just too big. So, is there a noticable difference between the 6750M and the 6770M? Thanks a bunch!
