lol quadcore, hp had 16 core machines out back in 2011.
So? This is the fastest chip available and massively out performs a 2011 16 core machine even a 2013 current 16 core machine in most tasks. You are not looking at the machine as a whole the Processing power on the Graphics card FAR outweighs even the CPU. CPU is less important these days for 95% of Task.
The people that are hanging onto Raw CPU power just don't get it at all. The GPU should really be called the processing engine. It's not just for Graphics anymore. ANY process could be fed thought the GPU with the right software. Video or Audio Compression. Database searching. Compiling code.
Oh and seriously you bring up Dell, the company with the worst return rate and Shocking customer service with their 28 day repair policy ( oddly great monitor service tho - 1 day swap out 3 year warranty!?! )
