awhile ago i came here inquiring about 480's in crossfire... been wanting to mess around with amd again so i finally decided to box up my 1080 and pick up two asus rx 480 strix oc's to mess around with.. so far being having a blast with them.
i really like the strix cooler and pcb design. the cooler works really well in a single card configuration. runs very quiet and stays cool both on the core and vrm's. since both are open air designs crossfire the top card was getting quite toasty and thermal throttling (saw the vrm's hitting 90c and the core once in a WoW session hit 90c as well!). i blame mostly my high ambient room temps. so i took advantage of the pwm fan headers on the cards themselves and modified my 400c and added two 120mm fans to the side panel connected to the top gpu and that took care of that issue. top card now runs in the 70's on both core and vrm's and the bottom cards stays in the 60's. both cards staying locked at 1310mhz.
i really like how asus added the pwm fan headers on the back of the cards. its nice having two dedicated fans following the cards temperatures.
overall price the strix series is a premium. and this premium price hasn't been a 480 exclusive. the new strix series has been priced as a premium for all series that far under its banner. from my own strix 1080, to even the 1060, which last i saw was selling for $330 on newegg. it does damper the 480's price to performance ratio but when you compare it to other strix cards it balances out. its marketed as the premium 480 for those seeking a premium... 480.
the nitro i find to be the best price to performance 480 on the market if all you seek is the best price to performance 480. clocked similarly to the strix and offers similar features.
right now i've been playing WoW rigorously since legions launch and the 480's run it like a champ at max settings. near 100% usage across both cards. performance stand point i cannot tell the difference between them and my 1080. i'm sure the 1080 is faster in the end but the performance delta is small enough where i can't notice it without running some benchmark.
i dabbed a bit into cs:go, doom, and fallout 4. cs:go has been fantastic. at first ran it with crossfire but it was overkill... set crossfire to disabled with a profile and one 480 is still overkill for it lol. doom is self explanatory and fallout 4 with crossfire performed as well as my 1080.
ran heaven and i scored 106fps at 1080p with everything maxed which is 2 fps higher than my old evga 970 ftw (clocked at 1.5ghz) in sli scored so pretty happy there. in time spy i benched identically to my 1080.
for the price the 480's really pack a punch and really impressed with how fast AMD has been turning out new drivers / bug fixes. i've been completely thrilled with them and loving polaris.
