Hi Guys, I'm planning to buy a new laptop because my current one (Dell Xps15z) cannot connect to a VGA cable for the projectors. That's one of the most important aspect that I need in this budget laptop and I don't want a laptop that would overheat while playing games quickly as I found out with my current laptop.
My Budget probably 500$-1000$ but I would prefer <800$

Currently I have these laptops in mind as I found out on the net:
-Lenovo G505
-Acer V5-552-X418
-TOSHIBA Satellite L55-A5278
-IdeaPad Y500 Laptop
-HP Envy Dv6-7210us
-Samsung Series 3 NP350V5C-T01US
-Toshiba Satellite L875D
-Acer Aspire V3-571G-9686

Also, can I know how Graphics Card are rated these days? I use to look at the Memory of the Graphics Card to determine it's capabilities but now I seem to see it measured in Mhz or something
