Everybody love branded items. When we say Dell, HP, Lenovo, Sony, Toshiba, or Samsung we think “Oh yes I love them”. That’s because they have a good reputation – mainly for busineses. But for home use, they are very slow because they install lots of their proprietary software on it (bloatware), which uses up majority of the system resources.
Buy alternative brands from companies who are top of their league for performance. Buy brand such as Alienware, Asus, MSI, NVidia, AMD, ATi, Intel.
