FSB Help! *Computer stuff*

I have a PentiumD 935 (Dual Core) 3.2 GHz processor with a FSB of 800MHz. I am interested in getting a new motherboard but it's FSB is 1333/1066MHz. Are these compatible? The new mobo takes LGA 775's, but the FSB thing is messing me up.
My processor:

Mobo i'm interested in:

The new mobo will allow me to cannabalize most of my components from my current system to the "new" one i'll build, but the minutae is what always throws me off.

Thanks,

Just buy a motherboard / CPU combo for not much more money. You can still use your hard drive, etc., and you'll appreciate the extra processing power. You won't be spending much more either.

If it were that simple I would have. Problem is this: with a new CPU/MOBO combo i'd have to upgrade my RAM to DDR3 and that compounds the problem. the mobo i am looking at will let me keep my DDR2 and processor but adds some more bells and whistles like 2x PCI 2.0 slots and crossfire/sli.
 
the mb and the cpu you're looking at should work...you'll be running at 800mhz (cpu fsb) instead of the mb's fsb.
 
So is the processors bus speed what a mobo/cpu combo default to automatically, or is whichever one the slowest bus what the setup defaults to? Just curious.
Thanks again.

Not all motherboards will automatically work with a slower FSB but in your case it will work fine with the 800FSB and CPU on the P5N.

Here is a direct link to the manufacturer page on that model so you can get a lot more in depth info:

According to the link you provided ( http://www.newegg.com/Product/Product.aspx?Item=N82E16819116262 )

Number of Memory Slots 4×240pin
Memory Standard DDR2 800
Maximum Memory Supported 8GB
Channel Supported Dual Channel

The board does not support DDR3 according to posts by other customers. Best to check the vendors web site. If you are using DDR2 800Mz RAM now, you should be able to re-use in this board. Always best to go to the mfg's website though and verify. As a note, Windows XP 32 bit (Assuming thats what you will use for an OS) only recognizes up to 4GB of RAM. One other thing, lots of interesting posts on the New Egg site about CONS. Not show stoppers IMO, but worth noting as potential risks.
As for mixing and matching a 800Mz FSB Proc with this board, check the MFG website or call New Egg. I am inclined to think it would not work. However, if it helps, for another 80 bucks or so, http://www.newegg.com/Product/Product.aspx?Item=N82E16819116093 should work. GL!

Thanks for the input. I greatly appreciate it! Long time, no see, by the way :)
So, to get to the details of what i'm thinking here are the components i'm trying to salvage and use on the new mobo:
Current processor- Intel D 935 Presler 3.2 GHz LGA 775
Current RAM- 2Gig's of G.Skill DDR2 800
2Gig's of Coursair XMS2 DDR2 800
Current Power- NZXT 550W SLI/Crossfire ready

And since the new mobo is good with my DDR2 and processor I'm planning on getting a pair of these ZOTAC video cards and SLI linking them to make my system a budget gaming rig. My OS is Windows XP (i think its the SE2 now since all of the updates it's been through) and it's reading all 4Gig's of my RAM.
Granted, i'm no computer expert but reading the tech info from newegg made it look to me like I could do this. You think it'll work?
 
I just checked ASUS's site and my processor is listed as being one it supports, so I'm in the clear that way. Wee!

If the MFG says the PROC isn't a problem, you should be good to go. As for adding video cards, especially gaming cards, watch your power supply. The power demands of video processors can add up quickly. Good clean power in a PC is step one of not having all kinds of 'issues'. The site notes that the video card you linked recommends a 400w power supply, that would be per card, your power supply link shows only a 550w power supply. IMO, I would seriously consider a power supply upgrade if you buy just one card, a must if you are talking about putting two in the system. On the idea of dual GPU's...Perhaps, *maybe* if you were using some sort of large monitor, say larger that 24", still, single, quality GPU's perform very well. Just know that two cards does not equal twice the performance, kinda like two skimmers won't necessarily yeild twice the filtration. FWIW I think that SLI/Crossfire is a bit of hype, perhaps designed to boost sales in a market where technology is over coming such needs. However, its your cash.

Got another question. If I want to run two of these cards, will my power supply need to be double the power requirements? i.e. the details call for a 400W power supply. If I want to SLI two of these together will I need an 800W or higher power supply?
 
No you do not need to have a full 800W power supply. However, you might be able to get away with the 550. I would personally go at least 600W. The rating for 400w power supply includes all the other devices.

It takes into account all the default devices in your box and gives you a total of everything needed to run with the 1 card.
