Inspiron 14 7447 vs Inspiron 15 7537 How's the Inspiron 15 7537 so far? I'm still choosing between the two. At base price, 14 7447's more expensive but is more powerful than the 15 7537. However, the chassis of the 15 7537 is luring me in-- the size, the expanded keyboard (I'll be using autocad a lot and I guess that's helpful), the silver aluminum finish. I have to upgrade the 15 7537 so much (that might be a lot of money) just to closely match the specs of the 14 7447. [They can be compared in the Dell Philippines website] But even with the best video card and processor upgrade for the 15 7537 (NVIDIA® GeForce® GT750M 2GB GDDR5; 4th Generation Intel® Core™ i7-4500U processor 3M Cache, up to 3.0 GHz), it still doesn't match the NVIDIA® GeForce® GTX 850M 4GB dedicated graphics and 4th Generation Intel® Core™ i7-4710HQ Processor 6M Cache, up to 3.50 GHz with Intel Turbo Boost Technology of the 14 7447. I honestly don't know much about computers. I just look at the numbers. Help with comparing? I need this in a week.
