will it make a big difference on performance with my system
<-----located over there.

Thank you

Depends what you are doing, it may or may not be something you will notice.

well i do some hd video editing, and play games like halo 2, not any demanding games.
under what situations do you think there would be a difference?

You may see some improved render times if you are doing heavy renders, what kind of video editing are you doing? Transcoding won't be a particular improvement sinc ethat is very processor intensive, but rendering an edit say AVI to AVI might show some improvement. In any operation tho, the only way you will see an improvement is if there is a bottleneck caused by what you fix. IE if Processor or RAM can't handle more thruput, changing the cache on the HD isn't going to offer any speed improvement. As with any other upgrade where you are looking for better performance, you have to identify the current bottlenecks on the system. We tend to think of a bottleneck as causing a slowdown. We might not see a slowdown, but every process has a bottleneck, it is simply the slowest portion of the process.
It is kind of like a water system, if you have 1/2 inch water line coming into your house, you will not increase the volume of water that can move through that line by doubling the size of the main 3 miles up the street - the 1/2 inch line is your bottleneck, when it is at max capacity, it is maxed.

i know that normally the slowest part of a system if the hdd. unless one has a raid system or a fast fast sdd.
i do video editing of just home videos in 720p or 1080p from my sony webbie hd camcorder, all in sony vegas movie studio platinum. with lots of effects and transitions.

With a lot of effects, the proc and memory is going to bear the brunt of the rendering hit. I just think if you are planning on seeing a lot of improvement, you may be dissapointed, but there should be some.

i have the lynnfield corei7 2.93 ghz. and ddr3 1333mhz ram. 8 gigs Kingston.
im not going to upgrade though. it is a 1 terabyte drive so it works fine for me.

also do you know if the processor i have, or a water cooling pump would make a high pitched sound? not really loud but enough to faintly hear. when i put my ear by the motherboard it sounds like the processor or from the area

CPU's can't produce any sounds. You might be hearing noise from the water pump or the radiator fan being conducted by the liquid.
