We have a performance review of the Colorful iGame GeForce RTX 3070 Ultra W OC-V. Like the reference RTX 3070 cards from NVIDIA, Colorful's offering features 1500/1725 MHz base/boost clocks, and 8GB GDDR6 memory clocked at 1750 MHz. Users can quickly overclock the card to a (conservative) 1770 MHz boost at the push of the aptly-named OC button. Naturally, we wanted to see just how far we could really push iGame RTX 3070 Ultra W OC-V with further tweaking!
