Hi, Im looking into finally getting an HDTV. Ive been looking around Ive narrowed it down to these two TVs. Theyre both 42" and 1080p, but one is 60Hz with Smart TV capabilities while the other is 120Hz with no Smart TV capabilities. I plan on using the TV to mostly stream movies from my computer. I can get the 42LV3700, 60Hz & Smart TV, like new from the Amazon Warehouse for about $615, while I can get the 42LV4400 new for about $550. Im not planning on putting the TV in the same room as my computer right now so streaming capability is a big plus. Is it worth it to get the 120Hz TV and a streaming device, or will 60Hz suffice? Thanks for any help!
