Hey guys! I got a AM3+ motherboard atm. I got 2 choices buy a AMD FX 8120 and a amd radeon 6870 and go crossfire or buy intel core i5 2500k and a intel motherboard.

If you already have the AM3+ then go with the 8120. No reason to waste the mobo.
March 3, 2012 8:13:15 PM

I could sell it. But not sure how much i will get from it. Will i notice a big difference between the fx 8120 and a i5? I will be playing wow, bf3, guild wars 2 and probally som other games. One more thing im thinking about is that 1GB is to weak. I already got 6870 and if i go amd i can buy one more if i go intel i cant. But will there be more games then bf3 that will need more memory on highest settings then my 6870 can handle? I can play on high on bf3 but on ultra i get fps drops.

I'd go with the 2500K and upgrade a better GPU later on. But it really depends onw hat you plan to do with the system.

I'd get the 2500k (or better wait a month for Ivy Bridge) and a stronger GPU, later. Strong single GPU > crossfire/SLI most of the time. No micro stuttering, support issues and so on.

But It's kinda lame beacuse i already got a AM3+ motherboard with support for bulldozer. If i go fx 8120 i can buy a extra 6870 and go crossfire. wont that give me more fps?

Right away, yes. In the long run, nope. :) 

I'd try to sell the motherboard (and the gpu) or build a second low profile system with these parts, later.

To get a better GPU instead. You can or have to wait with that, depending on what you get for the motherboard + gpu and what your current budget is. That's what only you can know. :) 

Ofc, you can wait with selling the 6870 or decide to still go crossfire with that Intel system, at any time.

That's a pretty good board and GPU, should have a good resell value. The cpu, not so much. Exact numbers, hard to tell. Maybe around 2/3 of the original price. Just guessing, though. Depends on how old the parts are, if they still have some warranty left and ofc how lucky you are with running into someone willing to pay a lot. ;)

They are about 6 months old and got warranty left.

Why waste your AM3 motherboard? Upgrading to intel is not worth it if you have a AM3+ motherboard already. There is no reason to upgrade really. Get an 8120, and then get a stronger GPU eventually, there is no huge benefit from a 2500k over a 8120.

Ok i think im sticking to amd. fx isnt so bad really. I will be playing wow bf3 and guild wars 2. should i buy a extra graphicscard for crossfire? i could buy a 1055t cpu if i want, or should i go fx?
March 3, 2012 9:46:45 PM

^If you're going to go phenom get the 1090t. FX and Phenom 2 are both fine (Phenom 2 actually has better performance, most of the time)
As for crossfire, it could benefit but I would honestly sell your 6870 and use the money for a newer card (560 ti, 6950, 6970 etc.) If not, CF with a 6870 will be pretty good still, like you will play games at high-max settings, depending on the game.

Why would you sell it? You get like 6fps more in BF3 with a 6950 in high.
March 3, 2012 10:38:13 PM

I could sell my 6870 and buy a fx 8120+6970 or buy i5+mobo and a 6950 and sell my mobo and 6870. but its not really a high performance jump from 6870 to 6970
March 3, 2012 11:22:51 PM

I'm sure that tricore is just fine for those games you're playing and FX will not bring much better performance. Check your cpu utilization and if it really gets maxed out maybe you reconsider. Sure BF3 is cpu dependent but I think more on IPC than threads so I'd wait a bit for keplers before selling that 6870 (just because of memory) and then buy 7870 or better.
6870 is one of the best value cards atm.
a b à CPUs
March 3, 2012 11:25:44 PM

I would go 6870 crossfire.

Anything from AMD is going to bottleneck that GPU setup a little however. Another thing, 8 cores isn't giong to help you in games, probably go for a 6 core (or Phenom II X4) and OC it as high as you can.

Unless you can get a good buyer for your mobo/X3 I'd say just stick with it for now. You'll still have plenty fine performance in all games. Then upgrade your CPU/Mobo when you need higher performance than 6870 crossfire.
March 3, 2012 11:38:09 PM

Ok, so you are suggesting me to get a fx 8120 and go crossfire? Even though i could get a i5? My im playnig bf3, wow and will play guild wars 2 and probally other games running on a amd athlon x3 425 2,7ghz overclocked to 3,4 ghz atm. I could also stick with the cpu i got now and buy a 7950. but wont it be a bottleneck then guys?

That is BF3. Very GPU bound game. Athlon II nearly acts like i5 in that game even with a GTX 580.

Everything in that post shows the 1090T performing better per clock than the FX-8120, so why would he get the 8120 when it performs worse?

If you are willing to sell the AM3+ mobo, then go with the 2500K and keep the HD6870. Save some money then get a HD7970 when the prices drop.

First things first, its AMDZone which is a AMD fansite. You cannot get a honest opinion there.

Secondly, these are his own results not a non-biased thrid party. He will cherry pick the benchmarks.

Third, the AIDA64 results are completley biased and skewed as he is comparing his highly overclocked CPU to stock CPUs.

Well, I view all websites that's not peer reviewed as being a bit biased, that's the reason you do not cite internet website or anything non-peer reviewed in literature, like Science and Nature. And no, the sites get the most views like Tom's, andantech do not necessarily imply their results are unbiased.

AMD does lack in processing power vs intel , but they do have areas that shine and technically speaking op is not going to see a big difference in gaming (bf3 etc)... If he does not have am3+ board I would advice him to get i5, but now he does so 8120 isn't a garbage choice.

There is a difference between a peer review and a fansite though. AMDZone is dedicated to AMD fans, it will always be AMD biased.

I originaly told the OP to go with the 8150/8120 but if he wants to sell the mobo and go with a 2500K thats his choice.

IMO it's way easier to buy something then sell without a loss...but if it's op's choice then yea off he go. If I'm op and can't return my board I'd stick w/ 8120.

And btw, Tom's is a more intel than amd site, at least for the cpu. True, fans will defend their brand, but not mindlessly as what most people assumes. Even though you may see ppl in AMDZone not suggesting ppl to buy Intel, they won't encourage ppl to buy Fx either; instead they say wait for Piledriver. I'd say unless you are some kind of special person, most people will behave accordingly on forums. Fansite is not equivalent to always biased. The result on AMDZone is just some data, and the author didn't suggest whether intel or amd is better. It is subject to the readers to interpret. You may view it as biased test or setup but it's up to you. And the author originally posted on Andantech and guess what, the thread is locked by a mod soon enough, that's why he posted on AMDZone later.

I have recently moved over from a high end 2500K build to a high end 990FX build and to be honest there is maybe a 5-10% performance gain in favour if the 2500K but everything is within margin of error, it is the fact that the bulldozer has gotten beaten in low thread counts by older chips that has let to the "Faildozer" hoopla. Sure the 2500K is better but it is far from a blow away chip, this fact was seen when the Bulldozers beat all Intel comers at BF3 benches. BD has hardware failings, but if the PD is 15-20% improvement then it will be right up with contemparary Intel chips, whether it is better or not remains to be seen.

If you already have the 990FX platform don't bother moving to Intel unless you can sell for value.

March 5, 2012 11:53:45 PM

Unless you have cash to burn off I would get the FX chip for now, crossfire the 6870, and you should be set for the next 18 months on 400 bucks total. In 18 months intel's Haswell(the Tock, which should mean a bigger leap) will be coming it out right about the time your rig will be falling behind.

Basically 6870s in SLI and the FX chip should be able to play just about any game on high or ultra for the forseable future.

No need to spend 700, 800 bucks on a 25% gain right now unless you have money to burn, and in that case-

Wait 2 months get IB 2550k and a Radeon 7950 or Nvidia 600 series, and a new mobo that supports PCI 3.0.

So basically my advice is-

If you are money conscience- Buy 1 6870 and FX chip and go home happy, save for complete rig overhall in 18 months or so.

If you have money to burn like having the best- Sell Mobo when IB comes out and 6870. Buy IB Proc (15 to 20% imrove over SB) get 7950 (or 600 series NVid) and OC it like a madman.

I will probally get the fx 8120 and OC it, got a 212 cooler. Probally aiming for the 7870. I can sell my gpu and cpu for about 230 USD. Then i only need to spend like 150USD to get the 7870 since i got a gift with about 50 USD left when i bought the fx 8120. It's not worth to buy a i5 isnt it?

since you said "probably" i'd suggest reading
AMD FX 8150 - 8120 - 6100 and 4100 performance review
http://www.guru3d.com/article/amd-fx-8150--8120-6100-an...

then its up to you if the difference in price between the 8120 and 6100 is worth it. to upgrade to an i5 would be quite a cost, worth it IMO but quite a cost . . maybe right now upgrade the best you can using as little money as possible.

btw, looking a *some* of those benches the 6100 was 85% compared to the 8120 at 75% of the cost.

While that article is an interesting read, the only time the 2500k walks away is in either intel software titles or in tri-sli.

They didn't cover the issue with civ v. It is very odd but in the built in benchmark the cpu does the extra work for crossfire, but only 1 video card has any usage. In the actual game, its just as strange, zoom all the way out, one card active, but as you zoom in, the second card becomes active (this is rl testing on my system). So if your main game is civ V, don't go with any amd, it does the same thing with phenom chips. But I will add, even with 1 of the 2 video card active the fps is still around 100 on 1080p.

As for bf3, I get no fps drops even in 64 player maps, 60-70avg on ultra. Haven't ran on high because my monitor is only 60hz, no point other than seeing the fps #:

^^ this is your answer.

Sell the 6870, get a 7870 2GB + FX 8120.

No point in going Intel at this point. An AMD FX 8120 ought to last you a long time and a 7870 2GB competes with the big boys (GTX 580).

So yeah... what he said.
