A quick check tells me that the socket is the same, however...

You will need to check the motherboard specifications for clock speeds and voltages and you may need a bios upgrade. Although chipsets are fairly standardized, motherboard manufacturers do not always implement all possible features.

Unless you have a burning need for power, e.g. you do a lot of 3D-ray-traced rendering of images, upgrading the CPU is rarely a worthwhile exercise.

yeah im recording hd video which is pretty darn intensive.

here are some specs
533mt/s 133mhz core clock
800mt/s 200mhz core clock
supports hyper threading

you could probably get a motherboard processor combo cheaper then trying to push an old P4 to keep up with modern times.

99 bux can have you a motherboard and dual core AMD, and then you'd be using faster DDR2 memory as well

Given the fact that it would be inadvisable ( despite what the chip manufacturers say ) to attempt to multi task on the same machine at the same time as you are processing your HD video ..or 3D

I would suggest setting up another dedicated to just these tasks( or multiple ) specific machine(s) ..which is what "we" do/have just to run such "intensive" ..work.

You will also ( if these extra machines have more than one HD ) see the benefits of having the processing app(s) not being on the same hard drive as the output files are targeted to ..

You may also ( which ever you choose ..be it upgrade or separate machine(s) ) wish to "adjust" your prefered OS ( shut down or strip out prior to the OS install ..non relevant functions ) to account for the specificity of your apps ..and thus free up cycles and memory and swap handling ..

Yeah I actually have about 10 computers here at the home office. This one that im addressing is a small little barbones box which is dedicated to my media. It also has 2 500g hard drives set up in a raid. And it is running as few processes as i can let it.

I dont know that i would but a new mobo that fits this thing, i probably just buy a new bare bones box before i did that.

The reason i originally pondered this is because you can get a dual core for pretty cheap now and that would give me the power i need to be able to handle the task i need to do.

What is the current OS / or the OS that you would install to use for the video work on it ?

my main pc is running win xp with quad core processor and the hd video plays fine on it.

its a minimum requirement from the manufacturer to have at least dual core to play and record hd video smoothly.

i can tell the machine that im trying to do this on is struggling just a bit. All i really wanted to know is if i can pop a dual core 775 in the mobo. if i can do this w/o risking frying everything than it may be worth at least trying.

you won't fry anything it just won't POST. Then you are stuck with a processor you spent $70+ that you can't do anything with except now purchase a motherboard that supports it or try to sell it.

exactly, i can start there. i can get a great used 775 mobo at goodwill computer works here in austin for $25.

so i know that i need more power, start with the processor and the mobo i have, if that works than great! if not spend more to get what i need to accomplish the task at hand.

Can anyone else verify that there is little or no risk of my popping a dual core 775 into what is currently a single core 775 mobo?

sure their is risk but i can't count the amount of times i've shoved a processor in a board I didn't know would support it or not without ever ruining a board or processor.

70 + 25 = 95

99 will buy you both NEW.

If you are competent with hardware and are prepared for down-time, you should be ok.
