I travel nonstop and work in industrial environments. What will be the best, reasonably affordable (under $1,500.00) notebook for using Solid Edge ST7. I receive some customer files that are 65mb or so that I have to manipulate. Any hardware suggestions will be appreciated as well. I currently use an ASUS N55S I7 processor with 8gb ram. It works ok until I get files that are 50mb or so. Then it gets sluggish. It is 3 years old and well-traveled (meaning beat all to heck).
