I will be upgrading the PSU soon and I need to decide whether to get the SeaSonic Snow Silent 750w or 1050w model depending on the future GPU configuration. I'm making my PC a full-on white / blue themed build with custom blue PSU cables. I was looking at the GTX 980 and 980 Ti HoF cards on the Galax website since the designs would fit my themed build perfectly. With DirectX 12 on the rise, I would need to find out if pairing a GTX 980 with my GTX 970 would be enough. Getting a GTX 980 Ti HoF and a 1050w PSU will cost $250 more than getting a GTX 980 + 750w PSU. I could use my existing GTX 970 as a PhysX card or a supplementary card on DirectX 12 games, but I think it's better to sell the GTX 970 and buy two GTX 980s for SLI. Should I sell the GTX 970 and get two GTX 980 HoF cards and a 750w PSU or keep my GTX 970 for now and buy a GTX 980 Ti HoF card and a 1050w PSU? I also saw an MSI GTX 980 Ti silver card, so maybe get that one instead of the Galax card? I'm planning on upgrading from a 1080p monitor to a 1440p 144 Hz G-sync monitor later on down the road.
