Apologies, did not notice your post on this page...pauldmps said:^^ I have clarified my view on this in my next post. Unfortunately, the datasheet was not available on the Lenovo site, when I last checked the site. So I drew my inferences from the video. (I saw the datasheet yesterday)
For comparison between GT-540M & GT-555, head to Computer Games on Laptop Graphic Cards - Notebookcheck.net Tech
And this is not a premium offering from Lenovo. I believe that the Y570 range will replace the existing Y560 series whose base model starts at 45k. So no backlit keyboard or full-HD screen.
Since my last visit to a lenovo exclusive store, i was under impression, for the dealer told me "ideapad Y series is Lenovo's top dog in home/multimedia laptops". So am I to believe that lenovo only caters to business people with thinkpad as premium offering?
And also notebookcheck.net does not have any real gaming statistics on gt 555m for now, i checked it earlier as well. So they placed the gpu on top just based on benchmarks/specs...
Anyways, gaming performance aside, vis-a-vis, dell xps 15 has more to offer in the same price bracket. So I still recommend it over Y-570.
