So right now I was planning on doing an SLI or CrossFire setup in my rig. Granted, that I need to buy a new motherboard. Now, I was doing some research and I found out AMD does not do Physx like Nvidia does and I also heard that running AMD cards in CrossFire have really bad stuttering and latency issues. Is this true? I have a GTX 680 right now but only 2GB version but I am starting to realize that 2GB is not going to be enough for upcoming games. While framerates will be crazy nice with 2 680's I don't know how long 2GB of VRAM will last me.. That's why I was thinking of the 7970 because they have 3GB or memory which will last for a good while I think and I can pick a couple up for 600 dollars or so. So please tell me what you guys think! Thanks for replies!
