I thought there might be a PC parts megathread or something in here, but I don't see one, so, new threads! I was planning to upgrade my PC with my tax returns, and I'm thinking that the processor is fine (4.2 ghz i7), the storage is fine (Could use a bigger SSD, but not that big of a deal), the RAM is fine (16 gb should still be fine, right?), so all I really need to do is turn my r9 390 into a 1080 ti and I'll be happy for another couple of years, I think? A) Does my motherboard or power supply or cooling need to be upgraded for that jump at all or should I be able to just swap those out, uninstall the AMD software and install the Nvidia software and I'm good to go? B) Will that be good enough for real, solid 4k gaming? C) What's the difference between the different 1080 Ti options? Different manufacturers and different prices, I don't know what I'm missing out on by buying an EVGA version for ~$800 vs, say and MSI for $1200. Is that a real world difference or is it just a product of availability or something? Thanks in advance!
