If the important thing is video editing and software, you'll want to go with the Acer because the GT 540M will KILL the HD3000 graphics. You would notice a big difference between the two. The Acer also has a bigger HDD which can be a nice feature.(750GB to 500GB). As for noise, or the performance of fast start, I can't say. But faststart is mostly just a gimmick, and sleep mode will be fine. I couldn't see that much of a difference. Again, Samsung PowerPlus Battery Technology is most likely just a sales gimmick, and won't actually give you that much of an edge on the Acer. Overall, from the specs I can see, the Acer seems like the obvious choice.
Most likely, you've already made your decision, since this was posted a while ago, but I thought I'd reply just in case haha.
