after reading many forums and reviews. Depsues hesitating between 650-660-660ti-670. I'd go with the GTX 670, it also has the option of 3D rendering. I will work with 3D in AE, but render time, This will go faster. It depends on the price difference 660TI with the 670 is around 40-50 €. I hope that I will pay extra worth.
Which brand is the best option?
Asus P9x79 Pro-Deluxe-Ws- Rampage IV extreme ( still do not know)
Sorry for my english.
I bought the EVGA GTX 670 FTW 4GB edition and I love it. It's on the 680 board so it stays nice and cool even with an overclock.
With that PSU, you don't have many choices. Only the GTX 650 may work somewhat and that is already putting a heavy burden on the PSU, all the rest take too muuch power, or you need to get a much better PSU (850W gold+ label), which would be my approach and then opt for the GTX 670/4G.
The warranties are what decide the brand to select. Certain ones like EVGA have lifetime warranties so that is what you are looking for.
