I’d love to keep it under $600 but that is seeming not possible. I actually purchased (2) laptops for under $500 in the last week and have had to return them both. Both have had ADM processors, both have been over 2 Ghz, with dedicated graphics cards, and at least 4 GB of ram, but for whatever reason both are running AutoCAD slower than my 5 year old laptop which has an Intel Pentium processor, and only 1.6 Ghz, 2 GB or Ram and no dedicated graphics card. Maybe it is because I dont have an Anthon AMD….?
