Here's my PC specs, just enough to make FFXIV run below average.

Case: Some cheap "Sentey" one
CPU: AMD Phenom 2 x3 @ 3.0 GHZ (OC)
Mobo: MSI 890GXM-G65 (MS-7642)
Memory: G.Skill Ripjaws F3-10666CL7D 1333 Mhz @ 1.5v
GPU: ATI Radeon HD 4650 (RV730)
Soundcard: Creative Soundblaster X-Fi Titanium (Pci-E)
HD: WDC WD3200AAJS-22L7A0 ATA Device (298 GB, IDE)
OPTICAL: Some LG DVD-R/RW
PSU: Some 600w one
Monitor: LG W2043 (Analog) [20" LCD]
OS: Windows 7 Ultimate x64

The game runs fine at mid-low graphics, but I definitively need to get a better GPU :/
The rest is just OK.
