Higher speed or lower latency? (XMS Memory)

[recover]

Should I go with the lower latency 2700 series or something higher like the 3200 without the low latency?

I'll be getting one stick of 512 with intent to add another in the future when some currency falls in my lap.

It's all corsair XMS memory, and I don't know if it matters, but specs (I haven't built it yet, so these are hypothetical, but pretty much set in stone) :

t-bred 2400+
Asus A7N8X Deluxe
Radeon 9500 pro
ETCETERA (let me know if you need more)

I'll be doing a lot of gaming, and there are points when I have visual studio, photoshop, and 5 IE windows up, so let me know.

Wordy post for what may be a relatively simple question? Never.

[edit] Forgot to ask if the platinum series makes any performance difference.

The 3200 will have NO problem at Cas 2 (Lower latency). If your going to overclock go with Corsair PC3200... if your not just get the PC2700. I'm running the same MB (A7N8X) with Corsair 3200... running the memory at about 190Mhz (380 DDR) with the best timings.
