So i'm looking to play current games on medium/high settings at 720p or older games at 1080p,and i'm on a super tight budget so with the HD7870, would a Pentium G4400 be ok at 720p? because up to this point i've been looking at the i3 6100 (which i'm still seriously considering, but you know, if i can cut costs i may as well look into it). i guess the real question is, does scaling down the resolution lower the demand on the CPU or will the G4400 always underperform when compared to the i3 regardless of the resolution. i have to determine the CPU before buying the MOBO/case so any infomation would be awesome!
