I have an okay setup but I know it's nowhere near the greatest, especially by today's standards.
ATI Radeon HD 5770 (with 1GB memory)
AMD Phenom II X4 945 Processor 3.00 GHz
8GB RAM DDR3
For all the other technical gaming stuff, I don't know anything else about my computer other than the rest is the parts I got from the store that came with it.
It does have a BD-ROM, and 1TB Hard disk drive, so that's kinda nice to have
I like my computer though.
I can play FFXIV on 1080p resolution, but I have AA turned off, shadows on medium, texture settings are mainly turned up high. Runs smooth for the most part, haven't had any problems yet. It's nice though. Mainly I'm just glad I'm able to play 1080p because when I put it down to 720p, the UI is way too big and covers a big portion of the screen (I hope they fix that, FFXI had separate resolution options for both UI and background settings).
