I have two ASUS 4gb rx 480s (oc'ed edition) that run fine but in some games like RE7 and the Witcher 3 I get constant stuttering in the fps, it usually runs around 150+ fps but sometimes drops down to 30 or so every time there's a quick action or something in the games. (I have tried lowering graphics settings; no difference)
Also all my games are on an external USB 3.0 hard drive
Specs:
Mobo: ASUS b35m-e
Gpu(s): 2x ASUS Rx 480 4gb
Psu: Evga 600 Watt 80+
CPU: i7-4790
RAM: 16gb ddr3 Hynix (2x8) @1600
SSD: Samsung 256gb
