A8-3870k with 5770?

August 13, 2012 12:32:11 AM

First of all, can my antec 400w psu(worth 50 bucks) handle the A8 with 5770?

Well I saw the 6670 vs 5770 here http://www.hwcompare.com/10882/radeon-hd-5770-vs-radeon... and the 5770 looks muuuuch better. I already bought a like new 6670 on amazon for 66$ but I think I can still cancel it. Well on amazon, http://www.amazon.com/Sapphire-Radeon-DisplayPort-PCI-E... the 5770 is only 85$! Would it be good if I just ditch the hybrid crossfiring and just get this 5770 and leave my onboard 6550d to do nothing?

The 5770 is much better then a 6670 + 6550d. Get that instead.

Yes, that PSU is more than enough for it.

And yes, HD 5770 is around 70% faster than HD 6670, so you will gain a lot by going with it.

Is that a good combo? 5770 with the A8? Also can my psu handle it? Would it be safe? Like what if my psu shorts out and blows my entire system.

I have a question, which is better, fx4100 with 5770 or a8-3870k with 5770? The fx4100 combo is probably better but how much better?

The PSU will be fine, just fine. The Radeon HD 5770 is a fine choice.

If you can reach a little with your budget you can get the Radeon 7770 GHz Edition and it'll really shame the 6670.

FX is better, but let me ask you: I guess you don't have any of the parts yet? Why don't you got with i3-2120 instead, it's much better than both FX 4100 and a8.

Actually I got all the parts and the pc is actually put together already, I'm using it right now.

I have M59 for case

400w antec psu

ASUS F1A55-M LE - FM1 mobo

160gb hdd

a8-3870k

8gb kingston hyper x ram

I'm thinking about returning the a8 and the mobo and getting a am3+ mobo and the fx4100 then getting the 5770 also.

And the 4100 is barely able to be called a quad core itself... 4 integer cores, but only 2 execution units. It NEEDS to be OC'd to get the most out of it. The 81xx is the real quad core of the FX line.

Besides that, a 2120 is a better all around CPU (compared to a 4100).

So which is better, A8-3870k or FX4100? Also, what quad core processor would be better than the FX4100?

If you want to stay with AMD, get an AM3+ board and a Phenom II X4 965BE. Much better.

No reason for a gamer to get an A8, and the 4100 is just pitiful.

how much better is the 965be? And yeah I did get a really good deal on the A8, should I go to the trouble to return the a8 and the mobo and get a different processor since I will be getting the 5770 and I wont make use of the integrated graphics of the a8?

That's really up to you, but yeah, a 965BE would be better than the A8 (3Ghz stock for the A8 and no L3 Cache, and 3.4Ghz stock for the 965BE WITH L3 Cache). Both can be easily OC'd, but the 965BE would always be better. It's not a night and day difference, but a pretty large one, nonetheless.

And with an AM3+ board, you'll have the option of moving to Piledriver, if it actually turns out to be decent. FM1 is dead, so nowhere to go with that.

Piledriver is the successor to Bulldozer due out in October (tentatively). It should be a decent step up from Bulldozer (basically what Bulldozer SHOULD have been). With a 965BE, it may still not be worth "upgrading" to Piledriver, but at least you'll have the choice.

And you're welcome. :)

You do know that the 6550D when asymmetrically crossfired with the 6670 will perform close to a 6770. 6770 like performance at a cost of a 6670.

That board would work, but I would suggest this, if you can swing the extra cash. ASRock 970 EXTREME3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard $84.99

If not, this is ok too. ASRock 970 PRO3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard $74.99

Just try to stay with a 9xx board or at least a 8xx board.

A8-3850 crossfire with HD 6670:

http://community.futuremark.com/forum/showthread.php?16...

http://www.tweaktown.com/reviews/4177/amd_a8_3850_llano...

If you can find a used 5770 or 6770 at a cheap price, I would skip the asymmetric crossfire....better video performance than 6670 all the time. 6770 is similar performance to 7750....7750 is more power efficient....not an issue if you have a good quality 400 watt power supply. Here, in Canada, I can pickup a brand new 6670 for around$50-$60. A brand new 6770 or 7750 is around $100 or more. I will probably settle for a 6750 for $80 since I would only be a casual gamer...or GTX 550 Ti for $95.

Try it out and see how it performs on your games...if you have time, try out the 6670 by itself on several games and benchmarks and then the 6670 crossfired with 6550D...run the same games and benchmarks. If you don't like it's performance, you can always upgrade your video card to a faster one later....prices on better video cards will continue to drop over time as new models are being released. Maybe something like a HD 6850 or HD 7770 will fall into your price range sooner than later.

Nevermind I think I'm gonna go with a cpu + gpu and not the a8 and 6670, I found the benchmarks and stuff and I don't like how the dual graphics only works with dx10 and dx11 only.

I read about the phenom ii x4 965 be and it takes 125watts! I used the psu calculator and it says 365watts is recommended, that's extremely high for my 400w psu. Here's my psu http://www.newegg.com/Product/Product.aspx?Item=N82E168...

I went on this site
http://computershopper.com/components/processor

And looked at top 10 processors, or AMD Athlon II X4 630 was 9, what do you guys think about this one http://www.amazon.com/gp/product/B005I2YN80/ref=olp_pro... ? It's cheap too!

How does the AMD Athlon II X4 630 compare the the phenom 965be and the a8-3870k? I want the AMD Athlon II X4 630 to be a lot better than the a8, if it's a little then I don't really care.

EDIT: I found this list http://www.cpubenchmark.net/high_end_cpus.html and it ranks the a8 is higher than the phenon ii x4 965(not black edition)

Actually, the Athlon II X4 630, would be slightly slower than the A8-3870K (200Mhz slower and basically the same, otherwise, with no L3 Cache. Also you can't OC it as easily), and it's certainly not as good as the 965BE, since it's better that the A8. I REALLY don't get where they get the idea that an Athlon II X4 630 is ANYWHERE close to the 9th best CPU. It's definitely MUCH lower than that. I mean they even rank an i7 3770K above the 3960X... That's completely idiotic, unless price is involved in that decision too.

And DON'T TRUST CPUBenchmark.net. The bench that it uses (PassMark) is totally, utterly, and completely useless. Also, the benches are user submitted and unverified, making it the worst thing that you could EVER use to compare CPU's.

This is a MUCH better site to use. http://www.anandtech.com/bench/Product/399?vs=102 That's not an EXACT comparison, but it's close enough. It's an A8-3850 vs. a 965BE, both at stock speed (and the 100Mhz difference between the 3850 and 3870K isn't really all that significant).

Your PSU is a good one, and it should be ok with a 6670, but it would be pushing it a little with a 6770 (the CPU doesn't matter as much (until you OC a lot), it's the GPU that really matters).

AMD recommends a 450W unit for a 5770, but a 400W unit might just squeak by (at least it's an Antec unit). That cuts it a bit close for me personally, but it should work, at least.

In general, they're about as reliable as they CAN be, but there are things they may not take into account (OC'ing both the CPU and GPU at the same time, max load on both the CPU and GPU at the same time, etc.).

The CPU and GPU OC part is what would push it over the top. If you never OC, or only OC one or the other, you should be ok.

I'm just one of "those" people that doesn't like cutting it that close, though. It'll work, but it's just a lot of stress on the PSU.
