This Whole PC is completely custom made, every part is brand new runs as fast as the specs are supposed to. Tested a Wide Variety of games on it including some very recourse demanding games and haven't had a single one be unplayable, and has always been a round 50-80FPS in some High Rescource Demanding games and 60-240FPS in most others on low to high settings. Very quiet even when the fans are running at almost max speed. Temps Stay Really low due to the good airflow through the NZXT Case. Overall a very solid pc for the average gamer.
