System is "Mid-Level" of a gaming PC. I couldn't give you a "High-End" PC since it is a Pre-built system, using possiblely a questionable PSU (I'm not aware of a 800W Corsair PSU), and no SSD. Granted it is a powerful PC, just not a "High-End" PC, as I would decribe "High-End".
Ok... I'll give you a little better ranking... closer to "High-End", but still a little below without a SSD and for the fact you are running a Nvida chipset (not the most recommended). Granted... I wouldn't turn down this system for my own
