Moving from my Zotac GTX 570 Zotac GTX 970 was the absolutely hassle free. Install old graphics card out, new in, boot up, new graphics drivers from the CD, get an update from the Internet and install - done. And, although both my motherboard, and the processor only PCIe 2.0 dominate. The screen settings have been taken over by the old GraKa. The performance gain is enormous despite PCIe 2.0. Both AC Unity and Thief running in the ultimate graphics settings. The card remains absolutely silent and a Spulenfiepen is also nothing to be heard. The whole thing you get for a currently unrivaled price. The Zotac GTX 970 I can recommend without any ifs and buts.
