Thank you all for the helpful responses, I like to stay around 500-600
dollar mark....this just for case/PS,memory,cpu,MB,video card. Not too
shabby , Uh!?
There are some comments on this page (which lists the various type
of Athlon64 processors), as to how much of a difference
S462/S754/S939 makes. S754 is maybe 25%, S939 adds another 5% more.
Whether 512KB or 1MB cache makes a difference (accounted for in
P.R. rating).

So, you've got $200 left for case/PSU/video card ?
Maybe $150 for a 6600GT PCI-E card, with careful shopping.
Newegg has some refurbs for a little less, and as long
as the card has both a VGA and a DVI connector on it, it
won't matter if any adapter cables are missing. You can get
Nvidia drivers off the Internet.
Leaving $50 for PSU and case. As I have no pride, any old
recycled beige colored steel box can hold my stuff -
try to find a used case somewhere. In my city, there are
a couple places that sell used computers, and maybe you can
get a case cheap that way. Make sure it has all the screws
and standoffs. I recycled one of my old cases, did some
cooling mods, and ended up with a very nice (but hard to get
into :-( ) case.
The reason for going cheap on the case, is many new cases
ship with a PSU in them, but maybe the PSU is not all that
great. No sense having an ultra-cheap bundled PSU blow
up your new stuff. I would rather spend the remaining
$50 on a good PSU, than spend the $50 on a case/PSU bundle,
where neither the case nor the PSU is that wonderful.
For power estimates, use this site
http://takaman.jp/D/?english
Substitute real measured power for the video card. A 6600GT
uses 4 amps from +12V, and the current comes from the ATX
main power connector. (See small table near bottom of page.)
http://www.xbitlabs.com/articles/video/display/geforce6600gt-oc_3.html
Takaman lists 3.3V@2A, 5V@7A,
[email protected] amps (before adding a
video card). With video card,
[email protected] amps, with 7.4 amps of
that for the processor. On a split supply (12V1/12V2 type),
that is 7.4 on 12V2 (the processor-only output) and 11.2 amps
on 12V1 (the motherboard/disk drives output). Their disk drive
power numbers are peak, meaning they are overestimating the
+12V current by a couple amps.
While this supply invests most of its energy in 12V rails, it
meets the above basic system requirement with ease, and the company
name is good. It is a 12V1/12V2 type, with no -5V output. The
20 pin ATX power connector comes with a 4 pin attachable piece,
that makes a 24 pin ATX power connector when needed. The only
parameter I don't like on this supply, is the holdup time of
12 milliseconds. Normally this is around 17 or 18 milliseconds
or so (could be important for surviving switchover of a UPS,
or taking power hits from your utility). Whether this is a
difference in the way they are speccing compared to other
products, I don't know.
