But if you are going to do video editing and gaming you need to look at;
Processor speed. I don't know AMD's too well but Celerons are the weaker of Intel's processors, usually used for starter systems. Personally I would stay away from Celerons.
Memory. Generally the answer is "As much as you can afford". Memory or RAM stores much of the application and work you are currently working on. RAM is accessed to store and retrieve data many times faster than writing to or reading from the hard disk. If you have insufficient RAM then the computer processor has to swap data in and out from RAM to the hard disk for the current process it is working on. This slows the process down. You can often see the effects of this when, for example, the mouse cursor changes to an hourglass whilst the processor is accessing data. The longer the hourglass displays, the more work swapping data the processor is doing.
For Windows XP 256MB of RAM is considered very low. XP will work on 256KMB but it will struggle. The AMD system has 512MB of RAM but I consider even that is marginal. For video editing and some gaming you need at least 1GB of RAM. I have 2GB.
Video RAM. You need a high end video card, (Graphics card). Video RAM is used in place of the system's RAM when videos are being displayed and with higher graphics games. There is no mention of which video card is installed in either of the two options you have given.
Storage. XP itself needs at least 10-15 GB of hard disk storage. Videos and music will take more. As with RAM, the more the better. Hard disk storage is cheap now, and so you should get as much as possible.
Make sure your DVD ROM is also a DVD RW. If you want to save/backup videos to DVD disks you will need not only CD RW but DVD RW.
You ask for help without the technical jargon. I'm sorry but it can't really be done without some knowledge of the terms used.
On the whole I do not see either example as particularly suitable for what you need.
im having to decide between these two desktops:
"Compaq Presario S5100NX
p4 2.6 celeron
256 mb ram
Genuine Windows xp"
"AMD XP 1900+ SYSTEM: COMPLETE AMD SYSTEM IN BLACK, 1900+ CPU, 512 RAM, 40 GB. HARD DRIVE, DVD-ROM IN A GREAT LOOKING LIGHTED CASE WITH EXTRA CASE FANS FOR COOLING, INCLUDES A BLACK MONITOR AND WIRELESS KEYBOARD/MOUSE,"
can you help me decide - without the technological jargon >.< - i need an experts opinion, so i came here.
im going to be using it heavily for movie editing, and burning things. gaming also. thanks you guys.
