Hey everyone,

I am going to be building a new system soon.

I had the E7400 in mind, but saw the price of the X3 710 (@ 120$) and thought I should consider it.

I will be using the system for gaming, and the other routine stuff (browsing, light photoshop, encoding, extracting/compressing)

I will also be able to overclock the E7400 to an easy 3.2 Ghz.

Which CPU do you think is a better bang for the buck since I do not want to spend more than 120$ on the CPU.

My GPU is probably going to be the ATI HD4830.

Thanks in advance,

I'd go for the X3 710. It overclocks well like the E7400's and has a third core. Go with the third core.
February 28, 2009 5:20:48 AM

Go with the X3.

go for the x3 720 its got an unlocked multiplier and overclocks like hell and takes on the e8400 and beats in some benchies and why go fot the 4830 when u can get the 4850 for a few xtra bucks??? happy gaming!

Thanks guys. Any specific motherboard for 100$? I read about the 4th core unlocking and I would like to have a motherboard that is capable of doing it.

Could you please suggest me some?
February 28, 2009 12:34:57 PM

the 4th core unlocking is mostly rumored to be on biostar mobos any way if u dont plan on crsfx then the gigabyte GA-MA78GPM-DS2H should suffice its a very good board and u can use the onboard graphics for hybrid crossfire here is the link

I recommend you bump the X3 up to the 720 BE, it's got an unlocked multiplier, it overclocks very well, it has the extra core over the 7400, and its only $20 more.
February 28, 2009 1:43:46 PM

So an AM3 socket processor would work perfectly fine with an AM2+ motherboard ( with the latest bios update for sure)?

Could you guys give me some more info on the stock heatsink/fan that comes with the new AM3s and the idle temps?
February 28, 2009 2:14:13 PM

+1 to third level the x3 720 is a black edition and u can overclock it like hell and yes all am3 cpu's are am2+ compatible.
will check out and let u know about the idle temps.

oh btw the 720be when oced beats the e8200 as well!
February 28, 2009 2:14:25 PM

sorry e8400
February 28, 2009 2:15:46 PM

Yeah the AM3 Phenom IIs are backwards compatible with AM2+ mobos and can use DDR2 as well.

February 28, 2009 2:45:23 PM

That is great. Being backward compatible and able to use DDR2 is really convenient.

I am asking about the idle temps because I plan on overclocking with the stock heatsink/fan. The only thing I will change is the stock thermal compound to ARCTIC COOLING MX-2 for 7$.

I will look for idle temps on google, but try to give me an idea guys.

Thanks,
February 28, 2009 4:29:09 PM

Wow, that didnt take long.

Dont go buying this chip thinking you can just "bump" it to a X4. If thats youre reason for wanting this chip then just dont buy it.
February 28, 2009 4:53:33 PM

Nope. I am perfectly fine with 3 cores. As you can see, I am looking at Gigabyte motherboards which cannot unlock the 4th core!
February 28, 2009 5:33:15 PM

both mobos are very good it depends on how much u wanna splurge on them!!!

remember more the sugar sweeter it is!
February 28, 2009 5:49:21 PM

Thanks for the link. Seems to be a solid CPU.

Any word on temps and how far it can be pushed with stock HSF and ARCTIC COOLING MX-2 for example?
February 28, 2009 5:51:37 PM

I've heard it can go 4.2 on air.
Now I highly doubt that it's going to happen for everyone, but i think if u invest about 20 bucks in an aftermarket cooler you can OC that sucker up to 3.7-ish.
February 28, 2009 6:17:45 PM

so wat are u still thinking about order that baby!
February 28, 2009 6:18:45 PM

oh do get the 4850 and post some benchies!
February 28, 2009 7:10:22 PM

I am not going to start building until a month from now. I am buying some of the components as they are on sale. I got an Antec Earthwatts 500W for 40$ (70 regular). I do not want to buy any of the serious components since prices might drop till then. I just want to have an idea of what is going to be a better bang for the buck.
February 28, 2009 10:29:33 PM

Yeah.

Now let me tell you something, even with OCing I recomming sticking with one good vid car as opposed to two mediocre ones in an SLI/CF setup. The reason is, the Phenom II is great, but not insanely amazing performance wise - which makes sense, considering its price. It'll bottleneck dual GPUs . With a single GPU + OC'd 720, you'll be a happy man.
March 1, 2009 3:22:42 AM

I am planning on buying the 4830 unless the 4850's price drops a month or two from now. I will start my build as soon as my semester is over, which means late April. Till then, I can research everything pretty well, so that I have a list of options to go with at the end. I will not be going the SLI/CF way though for sure.
March 1, 2009 5:57:55 AM

u r right but the 720be is good enough to handle 1 single 4850!

and u know wat i ran my 9600gt on a p4 3ghz which bottlenecked it by only 5% compared to c2d proccessors so u need not worry about bottlenecking and 4850 prices will drop soon as the new 4950,4970 and 4970x2 will be launched in march ny ati!
March 1, 2009 12:07:16 PM

A P4 and a 9600GT. That's not that bad of a combination.

I will sit and wait now and see how the prices fluctuate. You never know, nVidia might drop its prices and the whole equation would change.
March 1, 2009 1:45:44 PM

Nice I am getting me the same processor next week but Im getting me a single 4870 1gb Do you think It will bottleneck a little or not at all
March 1, 2009 2:40:33 PM

if you could unlock the 4th core and didn't you would have to be a fool
March 1, 2009 2:50:50 PM

The Asrock AOD790GX/128 with a SB750 cost $105. BIOS v. 1.3 does the job nicely.
March 1, 2009 3:00:55 PM

Have the people who unlocked the 4th core having any stability problems so far? Could time be a factor? Like after a certain amount of time, the CPU would go dead because it was not designed for this operational state. (power consumption or voltage for example)
March 1, 2009 4:19:03 PM

people with e8400 run a 4870 without any problems and the 720 be beats ity in most benchies so why should it bottleneck the gpu??? jus overclock the proccy and u should be fine! it also depends on wat resolution ur gaming at
March 1, 2009 4:42:39 PM

My success is summarized here, http://www.tomshardware.com/forum/page-258421_28_300.ht... one of the last few posts.

Yes, there are unstable 4th cores out there so don't buy expecting anything but stock. Time would theoretically have no more impact than with any other overclock. To get 3.7G with 3 cores I went to 1.55v and hit 45c when I stopped Prime. However given that I haven't even touched the FSB or HT clocks I think my current setup is a no brainer.
March 1, 2009 5:02:13 PM

I have read your post MISry and I have some questions. Did you run the CPU at stock with the stock HSF at any given time? If you did, could you please tell me what your idle/load temps were?

I plan on buying the processor and using the stock HSF but with ARCTIC COOLING MX-2 thermal compound. Any idea how far in terms of overclocking that will get me while keeping safe temps in mind?

Thanks

March 1, 2009 7:56:55 PM

I never tested it at stock speed. The fan it comes with remains in the box. Basically I'm not comfortable OCing anything without heatpipes anymore. They are out there in the $30 range but if you go for $40 you can pick up anything from a Vanquisher/Vendetta tower style to a lower profile Ninja class and have speed control as well as peace of mind. I've chatted with someone running 4.0 @ 1.7v and getting 60c under load. He's running liquid. The white papers say a topend of 1.55v and 60c. With the stock fan I would shoot for 3.2 and anything better in your comfort zone is gravy.
March 1, 2009 9:25:44 PM

Thanks for the numbers MISry. I think I can settle for a 3.2 until I buy a better HSF. Are you doing all your overclocking with AMD's Overdrive utility or BIOS?
March 2, 2009 9:16:17 AM

BIOS. I looked at both the AMD and Asrock ones and was completely underwhelmed.
March 2, 2009 9:56:27 AM

So I can conclude that the 720 is way better than the E7400 and competes with the E8400?
March 2, 2009 11:45:20 AM

yes its better than the e7400,has and xtra core which kicks in when u need it to and competes with the e8400 which is more costly which means we have a winner!

I hope you know u can unlock them!!!!!!!!!!!!!!! on my gigabyte ud4h i can press crtl f1 to bring up advanced bios options then you got into the M.I.T and go per core and set each core calabration at -2% i got my 4th core no problem on this board running like a dream. Only problem is this board has a quirk with the CPU multiplier. It cant go past 13x which is AMD 710 x3 standard. My cpu is seen as a AMD 10 x4

If i had to buy a budget processor. The E5400 would be bought before any Amd


And every one of your posts is blatant fanboyism.

The AMD X3 710/720 have a better upgrade path, cheap (and very good) motherboard compatibility, and a third core for the future, and things like GTA 4. Both overclock very well, and to similar speeds, and clock-for-clock they're pretty close, also. I'd go for higher future performance, which is the X3.
March 14, 2009 3:24:27 PM

I think I can agree that the x3 720 is a better choice than the e7400 at the given price level, however, every other post suggesting a e7400 always ends up going in the direction of the e5400 which is a less expensive processor @ $96 on the egg and when OCed has basically the same performance as an OCed e7400 (-1 MB in cache = no biggie). Depending where your budget is, it is definitely worth a look to save cash and potentially get you up there to a better graphics card...

In terms of "fanboyism" all I have seen on this post is a bunch of dude's playing ookie cookie with the 720...

My question to AMD is why does it take 3 processors to match the core 2 e8400's performance? It seems very sketchy to me... I have read on this post several times that the 720 when "OC'ed" beats the e8400, but is the e8400 also OCed during these benchmarks?? I have heard that the e8400 can reach 4.0 ghz easily. And depending upon usage, games don't show a noticeable improvement above 3.4ghz but other progs will...

I have been in the same predicament as xserver (OP) for quite some time with no resolution on a processor... I really like the price and 3rd core on the 720, I can't go e5400 b/c I want virtualization (check out youtube vids) so I'm stuck between the e8400 and 720 while trying to find money for the q6600.


March 29, 2009 1:16:57 AM

Hey Mountie,

I have found the E8400 on Dell home for 142$ with a coupon code. I am not sure if it is still available. Let me know if you are interested. As for me, I am going the 720 way because it seems to be more future proof.
March 29, 2009 4:15:57 PM

Thanks for the coupon xserver, but I've decided to wait... New processors are coming out April 20th, and prices should go down on everything (hopefully).

The x3 720 is a good choice and has the AM3 feauture which is nice. Great combo deals at the egg right now too. Best of luck with the 4th core if you're up for it!
April 3, 2009 10:51:06 AM

I am waiting too till after April 20th. Do you know what is going to be launched? I have not read any news about that. Could you please tell me more about it? Is it an Intel or AMD launch?
April 28, 2009 3:26:47 AM

I just bought a new setup cos my old machine died :( 

Using the stock cooler X3 710, runs real cool, no matter how much you push it, always below 40degC. And my box has 5 hard drives and a HD4870, so lots of heat and no cable management.

Look for some of those boards (Biostar, Asrock?) that will allow you to unlock the 4th core.
