Hi, I am looking for some expert advice on whether to upgrade my wife's Presario 5461, and if so, are the choices that I am considering the best ones?
Or, should I bite the bullet and buy/build her a new system?
Cost is an issue, if I can get her PC to perform reasonably for $100-200 on upgrades (vs maybe $800-1200 on a new system) that is my preference.
HERE'S THE CURRENT SITUATION:The Presario has an AMD K6-2 500mhz with 192MB RAM and a 40GB HD, a 10/100 NIC on fast DSL. The system is mostly original equipment except for the second RAM board, the second CD burner, the NIC card, and also I had to replace the original HD which crashed (also had to install new BIOS at same time). Plus we have added various peripherals but those aren't an issue.
It has latest OS updates, shut off all useless startup processes, we run antivirus and anti-spyware regularly so the software is lean and mean and clean AFAIK.
My wife uses it for running auctions on eBay, light photo editing, and other routine stuff like email and forums. It gets pretty doggy when rendering image-heavy large pages from eBay (which is a dog itself these days), or when running multiple browsers and other apps. She uses FireFox, IE6 and Netscape 4.7 variously, depending on which one works best with which sites. Also it has problems playing music CDs in the latest Winamp without skipping and distortion, however WMP seems to work ok.
Qwest recently upgraded our DSL to 1500/1000 kbps so the line speed is ok and I have tested it to be sure. It is connected via Ethernet to a 10/100 NIC.
The Compaq Presario 5461 system specs (selected specs from a loooong report by EVEREST home edition) are attached at the end of this post.
I have been reading a number of posts in this forum and other upgrade/overclock articles about the K6 family so that I think I have some idea of what is possible to do.
THESE ARE MY QUESTIONS:(1) What to upgrade?
Will I get a worthwhile performance boost by upgrading the CPU and adding more RAM? Articles say the K6-2 chip in it now lacks onboard L2 cache and that is a big mprovement the K6-III/III+ would provide.
The Gigabyte docs for the MB say it supports K6-2 and K6-III up to 550mhz and 384MB RAM, so I am hoping it will also support the K6-III+ CPUs as they are also Socket 7 chips.
Gigabyte Manuals link' ">http://www.giga-byte.com/Mothe...ual/Manual_GA-5SMM.htm
Also other articles say that K6-2 only handles 64MB RAM well due to cache issues and with K6-III+ it could handle the max RAM supported on the MB which the docs say is 384MB (3 x 128MB).
So if I put in some version of K6-III+ CPU and add 2 x 128MB DIMM's (replacing the 64MB in the first slot now), does that make sense?
(2) Which CPU?
I intend to run the CPU in standard mode if possible but if the only way to get good performance is O/C then I would like a CPU that supports that, which the K6-III+ family seems to provide. Which of the following would be my best choice? (the board and BIOS should support them AFAIK):
- AMD K6 III+ 450 APZ 1.7V Core Voltage
- AMD K6-III+ 450 ACZ 2.0V Core Voltage
- AMD K6-III+ 475 ACZ ?? Core Voltage
- AMD K6-III+ 500 ACZ ?? Core Voltage
- AMD K6-III+ 400 ATZ Ultra Low 1.6V Core Voltage
- other K6 chip?
Articles say:
ACZ chips are reported to overclock better than ACR chips
ATZ chip will OC to 600 very stable
(again I don't plan to OC but want to have the option if I need to)
(edited, forgot to add this

also what kind of cooling should I get, some brand of heat sink or do I need a CPU fan too? Suggestions welcome for this.
(3) Which OS?
Should I stick with the buggy but working Win98SE or upgrade the OS, and if so should I go to WinXP Home, will it run that ok with these proposed upgrades? Or should I try to find a Win2000 OS, would that run faster/better? As a side note I have WinXP Pro on my Intel DIY system and am very happy with it, so I'd probably lean toward XP.
4. Which Vendors?
Vendors for CPU that I am looking at include JLM Tech. and Upgradeability, are they ok or are there better sources? Probably will buy the RAM from Crucial or someplace like that.
5. Any other advice or questions?
Thanks in advance for any help. Sorry for such a long post but thought better too much info than too little !!
