how good is i7-4500u? Can it handle autocad, sketchup, adobe photoshop, video editing, office, and web browsing? it's for daily use, but will not use these applications all at once. it's 1.8 Ghz up to 3.0 Ghz with turboclock. is it good enough to handle any one of these applications? it's on my notebook choice acer, it has gt 750m 4GB, 8GB RAM, and 1TB HDD. thanks!
