I'm currently using an Acer Predator AG3620-UR21P with a GT630 2GB Graphics card. I want the GTX 670, but I'm pretty sure it will be too long or it will interfere with a part on the motherboard (not the memory or any thing else you plug into the motherboard). I would like to know if there are other graphics cards that have similar capabilities and are shorter that the GTX 670.
