Attempting to purchase a laptop for a pre-teen who loves Wizard 101 and such. Found a Dell Inspiron 15R for $600 with i3-350M 2.26Gh, 3 GB of memory, 250 GB hard drive, and a Radeon HD5470, 64-Bit, 1GB, DDR3 128Mx16x4pcs video card. An upgrade is available for the hard drive to 500GB for $66 or the processor to i5-430M for $95. But this is for a child and I do not want to go far beyond $650, if it is not really necessary. Would like to go lower that $600, but that seems like a waste of money for the laptop’s intended purpose. Ideas?
