That machine will run FFXIV maxed out quite well. You'll have no problems.
I'd have gone Intel + Nvidia for processor/video card. Intel is wiping the floor with AMD at the moment. What you've selected will work fine though so don't stress about it.
Only thing I would really suggest is trying to get an SSD in there for the OS. You won't believe the difference. It won't necessarily make your games run any better but overall "pep" of the system will be night/day verses an HD only system. My system boots cold to up and running with all background processes loaded in 22 seconds, including typing in my password, post SSD install. Single best PC upgrade I have ever done in 20 years of building PCs.
What SSD would you recommend.. also, what Nvidia video card is comparable to the one I currently have selected? I know intel is better for processors but it wasn't an option for the ones there I could pick.
It's not an option because the base machine selected is AMD so all the options are AMD related. The motherboards are not compatible with Intel chips. Also, the motherboard you have selected is not SLI compatible, so if you did go the nVidia card route, you'd be stuck with only ever using one card. You'd have to go to the next higher motherboard to get two nVidia cards to work together.
The closest nVidia card to the 7970 in terms of price and performance would be the GTX 660 2GB, which would add $36. But you'd have to add the next higher up motherboard for $117 for that to really be a sensible investment, and the 7970 is a really solid current gen card despite not being from nVidia. (See Passmark results for yourself.
Get the SSD instead. Out of the SSDs listed, I'd think the 128 GB SanDisk should work. SanDisk specializes in Flash memory so I'd trust them. (All my little SDHC cards are from them.) That's $38 more (if you get it instead of a platter drive - you can probably ask them to stick in a smaller platter drive alongside the SSD, say the 500 GB, as well.)
