I am looking for an all purpose laptop . Web browsing, office apps , autocad , video viewing and moderate gaming . Personally keen on the Z500
1- Does more clock speed on z580 and z500 (2.5GHz) as compared to dell 5521(1.8GHz) create a big difference in daily functioning ?
2- Effect of the different processors of both laptops on their battery life .
