im planning on upgrading soon (within a month or two) and i want to get a 754 socket mobo (dont need dual channel...yet!). however, because longhorn has been pushed back for a few more years, the chances that i'll actually utilize any of the 64bit instructions in the a64 any time soon are slim. so im wondering, should i instead get a sempron 3100 for the 754 socket? its cheaper than an a64, yet runs about the same, (with the exception of the smaller L2 cache, and only 32 bit, but then again, im not going to use it anyway). so in your opinions, what do you guys think; sempron or a64?
and im not an "enthusiast", i just want to use this processor for about 2 years or so before an upgrade, so i wont spend 400+ for an fx or 3800+ so dont bother suggesting that. :rolleyes:

Well if you're looking for something to use for 2 yrs, then it might behoove you to get the cpu that contains some 64 bit instructions...

well, in 2 (or 1.5, who knows) years, i doubt there will be any significant application that uses 64 bit. and we know that longhorn is a long way off.

I think you just answered your question yourself.

I think the sempron is a nice choice, 64 bit is still long in coming and even when it comes the transition will take years.

and according to Anandtech, the sempron 3100 runs almost as fast as a p4 EE3.2 ghz.

The A64 2800 retail boxed is only http://www.newegg.com/app/ViewProductDesc.asp?description=19-103-452&depa=0]$149 now, so I would hardly consider that expensive. I'm not sure how much the Sempron 3100 is going to cost, but it can't be much cheaper than that. And while the x86-64 path may be useless at the moment, I think the added cost for double the L2 cache is worth it.

So in my opinion, the A64-2800 is a better choice. And if it makes you feel better, I've seen people overclock them to 2.3ghz and up! :drooling: Not bad for only $149

well, monarch computers is going to sell 3100's for 129 (oem, i think), but according to some reviews, there doesnt seem to be any major difference between the two. and i really dont do that much with my comp. just surfing, some gaming, and the occasional graphic designing. damn, i so conflicted!!!

why are you so interested in socket 754? just upgrade your current processor to a athlon xp 2600 mobile and get a nice nforce 2 motherboard. your set for another 2 years.

$129 vs $149

for 20 bucks you get the better CPU, go Athlon64

i want a mobo that will last at least 4-5 years. i figure i'll be using longhorn by then (or at least more 64 bit applications). and i want to have a mobo that will last me a while, with minimal upgrades (save for cpu, mem, and vga)

Smart move... Athlon64 should last you a little bit better. And by the way, you keep mentioning Longhorn64... but don't forget about WinXP64. You can download the beta, which is buggy, but it shows signs of hope as far as an earlier release than Longhorn.

No such thing as a Motherboard that will last 4 or 5 years and still be fast enough for current applications. At least motherboards are cheap now. I remember when I bought my ASUS P2B (intel BX chipset) it was like $225.00. That was back when integrated was a bad word so you didnt get audio, lan, or anything extra either.

I'm also getting a 754 board I think the 939 stuff is too expensive and not that much faster.

is xp64 even coming out? i thought it was canned? anyway, even if it does come out, ill bet it'll be like windows me, in that it'll only last a year or so until longhorn comes out (theyre not the same thing, are they?). as for mobo's lasting, i've had my kt266 since august of 2001, and during those 3 years, i've changed my cpu once (1gig to xp 1700), my vid card once (gf2 to radeon 9800 pro) upgraded my mem once (256 to 512), my psu once (generic 300w to tt 420w) and added a dvd burner. its only now just starting to stretch thin when i play the newest games. but it still suits me fine for all my other computing needs. so im guessing that a 754 board (which is capable of much more upgrading) will last that long, if not longer.

oy... ok forget x86-64 :rolleyes:

Athlon64 is 20 bucks more than Sempron, so at the very least the extra cache on the Athlon64 makes it a wiser purchase.

When the semprons become more widely availible i suspect that the retail price for the 3100+ should fall to around $119. I think a sempron 3100+ c/ a GeForce 6600GT would make for an outstanding budget game system. Thats the direction I'll be going come October.

There's also the on-board memory controller to consider, and the perf benefit this brings to the table as well...

BTW, I haven't heard anything to suggest that x86-64 is going to be canned. I have heard that some of the drivers for it aren't quite there though... And a bit about further driver development, such as from nVidia here

I'd go with the A64 2800 just because it's about the same performance, with a lot more potential at the very least.

Well I didn't mention that because I think the Sempron S754 has integrated memory controller as well. The only big difference between a Sempron S754 and Athlon64 S754 is the the x86-64 pathway, and the cache size. They are otherwise nearly identical.
