Hello there! This is my second time asking a question on this site and it has been pretty good so far. I am planning on upgrading my GeForce GTX 660 Ti (EVGA) to a GTX 970 but I do not know what all the different versions of it are (like EVGA, Zotac, Asus, MSI, Gigabyte). My current GPU is 9.5 inches long but I do have a little more room if needed. My pcu is 1000 Wats I believe (See pictures below). I am willing to go up to 400 dollars but prefer less. Here is the link to what I am looking at and am confused about: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-970/buy-gpu
Thank you!
