I got the GB windforce 4070 (from OCUK) as its one of two 8pin 4070s that allow extra PL, just so you know it doesn't actually work and 200w is still the performance cap limit even at 216w limit.
Had I known the PL increase didn't work I would definitely go for two big fans over 3 tiny things, sure the triple fan is great on huge GPUs but this thing is tiny and though not loud is not a nice sound, I compared to the Ventus and the GB definitely has a more aggressive fan curve that gets to 1800rpm at about 60c, explains the great temps in reviews.
I always liked the GB cards but first impressions felt very naff (naff compared to FE), the hint sink fins had many dents in it and had glue all over the shroud and the fans are cheap as, very flimsy and tiny.
EDIT: have changed fan profile at firmware level and it works well at around 15/1600rpm much better and not much impact on temps.
Since you cant overclock past 200w get the asus dual surely will sound nicer?(you might be able to +8% PL apparently, if it actually works)
Clocks don't matter at all since all will OC at least 165+ and hit power limit before clock wall anyway so it doesn't matter.
For anyone interested OC +210 stable will bounce off 3000mhz mostly around 2880-2940mhz hitting pwr limit/Vrel constantly, stock is around 2760-2790mhz hitting pwr limit also.
Settled for UV 2835@1v +1000 mem and UV
[email protected] +1000 mem, using 1.035v and above at 2925+ will bounce off pwr limit and I prefer the consistancy of the clocks not dropping when hitting pwr limit.
