FFXIV Only - Low Benchmark Score and Low FPS on decent settings. Puzzled.

Thank you. Our processors are almost identical, you have half the ram and you're getting great performance. I just wanted to note my CPU Socket type is an Intel 478 socket in a G41 Family Chipset mobo. I always thought my general setup was fine, and I knew I was settling for less when I got the GPU. I'm also gonna need to up the PSU to maybe 500-600W from 400W, which contributed to settling for a subpar GPU.

EDIT: What PSU wattage do you have by chance?

Your CPU is Socket LGA775 not 478(old pentium socket).
Whats your amperage on the 12v line? check sticker on the PSU.
That 400w PSU should be fine for a 5750/6670
