I'm going to study B.Arch(Architecture) where there are plenty of graphics rich software like AutoCAD, Revit etc. For that I have decided to buy a Dell Inspiron 5547 with Intel core i5(4th Generation) Processor, 2GB of AMD ATI Radeon R7-M265 graphics and 4GB of RAM(Which can be extended further). Is it a good choice as my budget is a little tight?
