OK, for any CPU-intensive task, you want the fastest clock speed (GHz) you can afford, paired with the most cache memory you can afford. Once you figure that out, if you have extra money then you can add more cores. Examples: 1) Core 2 Duo 3.0GHz 6MB cache (if that beast exists) 2) Core 2 Quad 2.4GHz 8MB cache (if that beast exists) Number one would be significantly faster due to the higher clock speed. But you asked about video editing. That is one specific application where video card (speed), RAM (quantity) and hard drive (speed) all play a part. For video editing, look for: 64-bit OS with 6-8GB of RAM 7200RPM hard drive with 32MB of cache A recent mid-range video card like a HD 4770 or similar with 1GB of dedicated video RAM Your system might have other glaring weaknesses that will slow down video rendering more than a single core 2.4GHz CPU will. For example, if you have 2GB of RAM and are using "integrated" (on the motherboard) graphics adapter, then upgrading to a faster CPU will offer no performance improvement at all. -Dave |

By rendering, I'm not talking about in the Video Game sense, I mean processing video files with something like VirtualDub, Vegas Movie Studio - processing effects, converting to DVD etc. Depending on what software you are using, many video editing applications will use the GPU about as much as they use the CPU. The reason most people don't realize this is, the typical GPU is much more powerful than a CPU. So while the GPU is (relatively speaking) coasting, the CPU gets HAMMERED. If you are doing any kind of video editing, you need (at minimum) a pretty powerful mid-range graphics card with lots of dedicated video RAM. On a side note, the days of the CPU are numbered. GPUs are getting so powerful, they will soon take over all the CPU functions. -Dave |

By rendering, I'm not talking about in the Video Game sense, I mean processing video files with something like VirtualDub, Vegas Movie Studio - processing effects, converting to DVD etc. RAM will help and so will Hard drive speed, but there are still very few pieces of software that directly use the graphics card. When it comes to video proccessing a quad core processor is the thing to have. My rig is as follows: Q6600 o'clocked to 3.4Ghz (this way I get clock speed and extra cores) 4GB RAM 4x 500GB hard drives. 2 of these are set up in RAID 0 array for extra speed ATi X300 graphics because none of my software uses it. Hope that helps. -- Graham Website - http://www.thedeathzone.free-online.co.uk |

How is getting a larger PSU a waste of energy? How is a CPU a PSU? Benjamin BTW: an overszed PSU is in fact a waste of energy as most switching PSUs are working less efficient when loaded way below their maximum rating. If your PSU is junk quality, that is correct. -Dave |

On a side note, the days of the CPU are numbered. GPUs are getting so powerful, they will soon take over all the CPU functions This really isn't true. GPUs are very good at performing a very small number of tasks, and for those specific tasks, no modern general purpose CPU can compete. General purpose CPUs' days may be numbered, but it will take more than GPUs to replace them. What you fail to realize is that it would be trivial to design a single chip to perform both functions. We already have quad-core chips being the de-facto standard. How long do you think it would take AMD/ATI (for example) to integrate a CPU into a GPU fab? It's coming. Now you know why AMD bought ATI. They needed to. -Dave -- Dave C. |

* muzician21:

Well, except the intel Atom and similar low-power CPUs of course you probably will have a hard time finding a somewhat newer CPU that doesn't give you a very noticable performance improvent. Not too proud to go used, can't afford the latest greatest, but would like to see a "significant" jump in speed. Well, a P4 2.4GHz sounds like Socket428 to me, and honestly, everything you can get for this socket is old and slow. However, if your mobo is already Socket LGA775 then it depends on the mobo. Older LGA775 boards are limited to the Pentium D (basically a dual core Pentium4) which will already give you a noticable performance boost (get a Pentium D 9xx not the old 8xx series, though!). However, if your board supports it then the Core 2 Duo/Quad is the way to go. Benjamin |

* Dave C.:
OK, for any CPU-intensive task, you want the fastest clock speed (GHz) you can afford, paired with the most cache memory you can afford. Well, usually a good advice is to buy enough CPU power appropriate to the task. Going above that is a waste of money and energy. Once you figure that out, if you have extra money then you can add more cores. Examples: 1) Core 2 Duo 3.0GHz 6MB cache (if that beast exists) 2) Core 2 Quad 2.4GHz 8MB cache (if that beast exists) Number one would be significantly faster due to the higher clock speed. This is only true for single threaded applications. With multithreaded programs #2 runs circles around #1. And figuring out how many cores can be used by the software should not be secondary in the list, it should be the first thing that is checked. But you asked about video editing. That is one specific application where video card (speed), RAM (quantity) and hard drive (speed) all play a part. This is not quite right. First, if the video editing software is no 64bit application then buying more than 4GB RAM is a waste of money for that task. Second, only very few editing programs actually support GPGPU functionality, and those that do use it only rudimentary. For video editing, look for: 64-bit OS with 6-8GB of RAM While I agree that when buying a new OS it makes sense going for the 64bit version, there is no reason why the needs to buy a new OS just because he wants a faster system. 7200RPM hard drive with 32MB of cache A recent mid-range video card like a HD 4770 or similar with 1GB of dedicated video RAM As most video editing programs that support GPGPU still set on NVIDIA's CUDA recommending a midrange ATI card isn't a good recommendation. Any low-end card (Radeon 4200/300 series, Geforce GT120 etc) does as well as a Radeon 4770, is cheaper and consumes less power. Your system might have other glaring weaknesses that will slow down video rendering more than a single core 2.4GHz CPU will. For example, if you have 2GB of RAM and are using "integrated" (on the motherboard) graphics adapter, then upgrading to a faster CPU will offer no performance improvement at all. This is complete nonsense. Every integrated gfx solution benefits from a faster processor as it offloads many things onto the CPU. In fact, for any video editing application that does not have GPGPU support an integrated graphics solution does as fine as any separate graphics card. Following your recommendations, the OP would spend a ****load of money for something which brings very low or even no return in value. Benjamin |
