High textures are xb1 textures. I presume they do not fair as well with less than 3 GB of VRAM. Then again, I am not positive.
Have there been reports of how 2GB cards fair on high textures?
Before I open up my tower for nothing: will it work with a MSI GTX 970 Gaming 4G? The MSI cards doesn´t have a PPID and the SN is formatted differently, afair.
