So, I broke down and decided to build a new system before FFXIV is released. It's decent enough, and cost me around $1250 after rebates.
My last few builds have been Intel-based, and I know how well the i5 750 performs in games, but I've really been disenfranchised by Intel's upgrade paths, especially after considering the fact that Sandy Bridge will probably use a different socket than either 1156 or 1366. So I went with AMD this time around. A hexacore processor at a $200 price point was very attractive.
Anyway, here are the components I used:
CPU: Phenom II X6 1055T
Motherboard: ASUS Crosshair IV Formula
RAM: G.Skill Ripjaws 4GB (DDR3 1600, CL7)
GPU: XFX Radeon 5850
Case: Corsair 700D
I was thinking about going SSD, but I think I'll wait until more SATA 6.0 drives are released. And the prices need to drop, too.
I'm actually rather disappointed by my overclocking so far, especially for my CPU. My temperatures are outrageously high. At 3.8GHz, I'm running at 1.34V, and I'm hitting around 60C under full load. Most people don't go above 55C using 1.4V-1.5V, AND they're passing the 4.0GHz mark. I'm going to have to work on this a bit more. Maybe reseat the heatsink, or add another fan to the mix.
As for the video card, I'm running with the core clock stable at 860MHz and the memory clock at 1275MHz. I'm kind of annoyed that I'm not able to get the core clock higher than that. I've actually gotten the memory clock up to 1340MHz on its own, but the system crashes as soon as I touch the core clock.
Long story short, I'm getting a 4500 on the FFXIV benchmark, and that ain't too bad.
The Windows Experience Index doesn't look too shabby, either (barring the abyssmal HDD performance):
