Wait... which G.Skill kit do you have?? And at what speed is it failing you??
You probably will see little or NO increase in performance with faster RAM. If you set that RAM 1:1 with the CPU, you can crank the FSB up to 400MHz before RAM even hits stock speeds! That's a CPU clock of 3.6GHz, and it's pretty likely your CPU will have more trouble with that than the G.Skill RAM.
Plus, if it's an G.Skill HK or HZ kit, it will likely overclock to DDR2 1000 speeds or beyond, allowing you to run a 4:5 divider. The faster RAM likely won't allow an 2:3 divider at a high CPU overclock, so it's probably a waste of money.
Plus, in gaming, faster RAM doesn't matter a whole lot, if anything. I tested DDR2 667 v. DDR2 1000 speeds (at identical CPU and FSP speeds), and I had 0.3 seconds difference in SuperPi 1MB, and NO siginificant difference in 3DMark06.
My advice: stick with your current RAM, and game on!. And we're talking BF2.... not a real challenge for a Core 2 Duo/DDR2 rig.
