so my girlfriends son has a dell 620 i got for him that started life as an i3 2100 plus 8gb ram, a 7750 was installed, but fortnite performance was terrible on low/low res with just about reaching beyond 15fps, now ive upgraded it with an i5 2400 and gave him my msi gaming gtx 760 along with appropriate psu and boom high settings and higher res with 80 plus fps, plays great apart from minor wifi stutter, but with only a single exhaust fan im thinking it might get a bit warm, so thinking about changing the case, however i know some dell cases cant take gaming boards, but not tried a dell in a gaming case to know if or how much they are offset given the propriety nature.
