In case you haven't heard, NVidia has released a benchmark utility for FF XIV (http://www.finalfantasyxiv.com/media/benchmark/na/). I spent some time this evening checking different configurations to see what needed to be upgraded in my system to play the game well.
Just to give you a base of what this game is going to take, here is my setup:
Windows 7 64-bit
Core i7-920 @ 3.6Ghz (overclocked)
6GB TriChannel RAM @ 1800Mhz (the RAM is 2Ghz but timings don't work with OC)
10,000rpm HD (SATA Raptor)
Nvidia 9800GT PCI-E
In 1920x1080 (1080p) resolution, my system got a "1750" rating. It was horribly laggy looking, I'd guess something like 10-15fps. According to them, " [1500-1999] Low Performance, Capable of running the game, but will experience considerable slowdown. Adjusting settings is unlikely to improve performance. "
In 1280x720 (720p) resolution, my system got a "3150" rating. This actually looked pretty good, but you could tell there was still a good bit of performance increase that could occur. " [3000-4499] Fairly High Performance, Capable of running the game on default settings. Consider switching to a higher resolution depending on performance. "
Now here's the kicker:
I tried knocking the system down from 3.6ghz to 2.6ghz and memory timing from 1800mhz to 1088mhz. I got the exact same ratings (+- 10 or so points). So basically, if you are out there and have a pimp CPU, fast HD, uber memory, but an older GPU (that plays TF2 or World of Warcraft at 120fps on the highest settings)... go ahead and get ready to buy a new graphics card. This game doesn't care how fast your CPU/memory/HD IO are until your graphics card gets to a point that it matters.
I want to play in 1080p since I have a massive monitor, so assuming I got 15-20fps... I'd need a GPU 3x faster (probably not linear) to get me 60fps in this game. So, think in the GTX 400 series if you want to play the game on tip top settings at high res, and possibly even SLI at that. I'm probably going to try out the GTX 295 and see how that does.
