Hey guys, I'm kind of new to this GPU stuff so I'd like to ask for your advice on something. Right now I have a Strix GTX 970, and I'm kind of upset about this 3.5GB VRAM thing. I heard that the 8GB version of the 970 is coming out soon, so I was thinking about returning my current 970 and buying an 8GB version so that in a few years I can buy another one and run SLI. I assume this setup is going to last much longer than a single GTX 980, maybe for another 5 years or so? What do you guys think?
