So I've asked this in Moe's but I think I might get a quicker response here.
I'd like to build a new computer. The motherboard I've selected takes an Intel 775 socket processor and supports up to a 1600 MHz FSB, and DDR3 memory. None of the 775 processors I've seen on Newegg have 1600 MHz FSBs--they're top out at 1333.
My question:
If I get a processor running a 1333 MHz FSB, does it make sense to get RAM running at 1600 or will it be bottlenecked by the processor/FSB?

If you buy 1600-rated RAM, and don't overclock your 1333MHz processor (and remember many CPUs are still 1066...watch what you buy!), the RAM will run at 1333MHz. The Moe's people who do this shit can further elaborate. There was also a couple of interesting articles on the benefits (or lack thereof, in some cases) of overclocking RAM on Anandtech and TomsHardware a few weeks back.
Quick note: Ok so one 1600 FSB processor exists. It's a $1500 Core2 Extreme.

EDIT: Oh, and thanks! How rude of me.
In laymans terms, not overclocking, it still might be possible to run the memory at 1600, but only if you have the right board and chipset.
Just be careful OC'ing. I've heard plenty of people push their board/chip/memory too far and burnt it up.

Just a friendly reminder. Don't push it too far or you WILL be sorry.
Thanks for the overclocking caution. I figure I'll try a step up on the FSB and if it doesn't work I'll set it back--it wasn't that much more to get the DDR3 1600 over DDR3 1333.

You can overclock the memory just fine, but you probably won't see huge returns unless memory transfer is your bottleneck - by all likelihood you'll hit a video or CPU bottleneck way before that.
Can trade TF2 items or whatever else you're interested in. PM me.
What model XPC? I would like to take a look at the manual. Outside that don't overclock anything. Me I would buy high performance parts that I could under clock and under volt.
I'll definitely want to look at temperatures. If I remember correctly (it comes today but hasn't yet) the thing has 4 case fans, though, plus the video card exhaust fan, and it's about the size of my cat...so I'd be surprised if it wasn't changing all the air out of the case in just a couple seconds.
Shuttle SX48P2 DELUXE Manual
Parts are already bought now (after I'd received the first few answers) and are as follows:
Shuttle Case
Core 2 Duo E8400 Wolfdale @3.0 GHz
8 GB (4x2GB) OCZ Platinum DDR3 1600 MHz
Seagate Barracuda 1TB HD
...and perhaps most ridiculously
XFX GeForce GTX 285 w/1GB VRAM

For someone who's "never overclocked before" you've definitely got your head screwed on right when it comes to it. Exactly the ratio you want for factory speeds.
Now, if you're actually going to try OCing that bitch, you'll probably just shoot for 1600FSB on the chip, and a 1:1 ratio, giving you an end result of 3.6GHz.

I've just never bothered upclocking a system--until my previous build it was too dangerous, and for several years my computer just ate up everything that came its way anyway so I didn't bother. I probably wouldn't have even asked except that this board supports the higher FSB clock and I couldn't find a 775 processor that also did.
It's sounding attractive now, though. Right now I've just got the CPU : DRAM multiplier on 5:6 and am running through all the pain-in-the-ass XP64 setup stuff (because that's what I had lying around). So far it's been damn quiet--it'll be interesting to see how the fans crank up on low. Especially since the 3D card is kind of trying to ingest air from the same couple ccs that the CPU is.
I do believe I'll try overclocking it once I've got the system loaded up and running and then reporting what happens.
Like I said somewhere around 3:4 8-). You are correct it is 5:6, I was only doing a rough estimate in my head quickly as I was packing up for the day.
It's not immediately apparent to me how to set the FSB frequency using this Shuttle mobo. I can bump the processor up to 3.6 GHz no problem using the multiplier (max 9) and the CPU clock setting, which gives a marginal increase on the RAM speed (though it's not up to 1600 yet).
I can also bump up the FSB voltage, but the result of this isn't readily apparent to me.
Anyone mind having a look at the manual I linked and hand-holding me a bit more? I feel like I'm just not making the proper connections here.
If you overclock your rig a lot it sometimes needs a little more juice to remain stable, increasing the voltage won't actually give any benefits other than possibly stability but I've heard horror stories. There are lots of other reasons your system could be unstable (if it is) so don't just crank up the voltage thinking it will solve it.
Your are already at the point you need to be at the trick might be if your able to lower the multiplier to get a higher buss speed.
You guys have any preferred programs to keep track of temperatures, etc? I haven't heard the fans crank hard yet (so far it's quieter than my old rig) but it'd be some extra assurance.
