I currently am running AMD64 3000+ on my machine.

Someone is selling their 64 X2 3800 for $60

Is this a worthwhile upgrade? How much faster will my PC be? I play games, and burn dvds a lot on it.

Make sure it's the same socket, but yes, that's a great deal. For single-threaded games, you won't notice any real difference, but for newer games and encoding/multitasking it'll be a very nice leap.

??

Well they're available in both sockets, so just make sure the one the guy's selling matches your current socket and all is well. :)

Could look for an Opteron 165/170/175 in the FS/FT :)

And no, if he's running a socket 939 w/A64-3000, then the X2 would use the same mem.

I thought the A64 3000+ was skt 754. My cousin upgraded to a c2d in jan b/c he couldn't get a decent chip on 754. I wish amd would try to keep the same socket "current" for more than 18 mos. I hate to toot intel's horn since they do enough of that on their own, but they have skt 775 around since before global warming became a hot topic. Hmmmm, 775, global warming, could there be a connection???

They made 939 3000+ A64s, but terminated them pretty quick.

I'm running 939

Now the guy is offering $60-65

but I can get the CPU new from new egg for 70...should I bargain a little? In which case...I could just buy it new...but is 70 dollars worth it? I'd be running XP.

that's a better deal than 3800 at 64 imho. plus, you can sell the junk ecs mobo for 10-20 in fs/ft or on ebay.

where is that deal from frys? in the local paper? I didn't see anything like that on their web site.

If the chip the guy is selling is a proven overclocker, you might just want to put down the $60-$65 and buy used. Otherwise I'd get the one from NewEgg and hope that I wasn't getting someone's recycled RMA.

Any x2 3800+ will hit 2.6ghz. Unless your mobo or psu sucks, but I yet have to run into a x2 3800+ not hitting 2.6ghz. So no reason to go with a proven overclocker if it's used. I wouldn't give him more then 40$ for the cpu, unless he bought it new a week ago, then 50$ would be reasonable.

I agree, If its coming with a HSF that you can use for OC then $60 is an ok deal, if not then you can get a new 939 x2 3800 from newegg shipped (OEM - no HSF) for $63. I wouldn't buy it for more then $40.

If you need to buy a decent HSF( and no a decent single core HSF will not cool a x2 overclocked very well - my zalman 7700 couldnt handle my x2 3800 @2.7ghz ) then you may want to get the opteron 165 for $99 as the HSF on the retail x2 opterons should handle any moderate overclock (~2.7).

AMD 939 cpu's

The increase in performance going to dual core will be great for dvd ripping. You will also notice a boost in the everyday operations when running multiple apps. The disk IO will now be the obvious bottleneck as the cpu?s wait for something to do.

As for gaming, if the game is coded for dual core there will be a boost, if not then the game will play the same as a single core of the same speed plus or minus a few percent. The real performance in gaming comes from not taking a performance hit when still running a browser, IM, and other misc apps while gaming. My avast AV will update my virus def or run a scan, and I will not even notice when its happening except if the apps/game relies on disk IO.

I currently have amd 64 3000, and i used the stock HSF.

Can I use the same HSF? or do I need to use the one that comes with a dual core?

bryan, not sure where you are located, but I usually go to the OCRegister site to get Fry's ads. Hurry if you still want to get the cpu combo. Today is the last day. http://ads.ocregister.com/rop/...ocr/category.php?id=17

Usually good for all So-Cal Fry's stores. In fact I think they usually offer it nationally (of coz they only have stores in a few states).

i'm in tx. they have frys here but they're too far away to make it worth the savings. :(

Tiger Direct link.

63 shipped at newegg (as two of us have already mentioned) is probably going to be better than 59.99 + shipping at tigerdirect.

do not try to use your existing hsf for an x2. get the x2 3800 and a decent aftermarket cpu cooler. arctic freezer 64 is nice but but you are limiting yourself to only a64's for potential future use. opteron 165 does come with a great hsf but you're paying almost $40 more for it. I personally had a bad experience with an af 64 but there are many others who had great experiences with them and the price is right. If your buddy is selling his with a good hsf then that might be a good choice.

yup

from experience a hsf designed for a 3000+ is not going to sufficently cool an AMD x2 core cpu, especially if overlclocking.


$60 with HSF = solid
$60 cpu alone = bad, might as well buy new for $3 more.
