Hey everyone. I spent the last week or so diagnosing a motherboard issue that caused me to lose the use of my second GTX 780 because of a faulty PCI slot. This showed me how weak a single 780 really is in regards to 4K gaming on modern games. So, I decided that I would like to upgrade to one single card that is a bit more powerful. I’m not longer making the income I was, and cannot splurge on a $750 card because I am now a full time college student. I was looking at used GTX 980 Ti’s, and it seems they have become pretty affordable at around $300. My question is that I am curious if it is worth the $300 to upgrade from a single GTX 780, or even SLi 780s (fixing motherboard issue causing no SLi) to a single GTX 980 it? Are they really that much faster in 4K gaming? Just looking for real world experience on this. Thanks!!
