Nividia has teamed up with Blizzard to offer an exclusive bundle for Heroes of the Storm with the purchase of a GTX 950 or 960 graphics card.
The bundle contains the Diablo character, the Kaijo variant skin, and a seven-day stimpack. The stimpack will grant you a 100% experience and 150% gold bonus while active.
Nividia launched the GTX 950 specifically for the growing MOBA audience. The 960 will grant you higher quality, albeit at increased cost.
