FX8150 + crossfire bottleneck?

[Kaylix]

Hello all,

I'm currently building my first computer and have some parts I already have and some I still have to buy and I'm not sure whether I will run into problems with bottlenecks and PSU usage. I hope you can give me some advice and judgement about the set-up Ive chosen!

The parts I already have:
Board: Gigabyte 990FXA-D3
CPU: AMD FX-8150 8-core 3.6 GHz
RAM: 16 GB DDR3-1333 Geil Black Dragon (4x4 GB)
PSU: OCZ Modstream 700W
SSD: ADATA S511 120 GB SSD SATA 3.0

The parts I still have to choose:
Videocard: 2x Sapphire 6870 running in crossfire

Will this be a good system or will it be bottlenecked or have better alternatives?

Thank you!

I wouldn't recommend the AMD FX. Its only about as fast as an i3. It's very inefficient and uses a lot of power. Depending on your budget you should get an i3 or an i5 instead. Also you should get 1600MHz memory instead of 1333MHz, and if all you are doing is gaming then you wont need 16gb ram. Only 8.

Buddy, you need to brush up on your facts, The fx is a lot faster than an i3, a 4170 and an i3 are the same in GAMING, but not in everyday tasks, or more cpu intensive tasks or games. Go on the front page and look up the cpu hierarchy chart. I have a fx 4100, and compared to my brothers i3 setup, it destroys it.

Well then go with the FX, but I would still recommend 1600MHz ram

Here are some benches from toms. The i3 is usually better than the 4100. They compete but in no way will a 4100 destroy an i3. And willze7 is right. The fx series draw a ton of power. I will say that I think the 8150 compares to the 2500k for gaming only. Ive also seen that the amd processors bottleneck xfired gpus.

Here's the 8150 vs a 2600k with xfired 6970's...

guys what about you read the OP post he said: The parts I already have:
Board: Gigabyte 990FXA-D3
CPU: AMD FX-8150 8-core 3.6 GHz and you are suggesting him intel LOL, your FX8150 will be fine for those GPU man dont worry, i saw someone in Youtube with this FX8150 and GTX680 SLI and didnt have any issue

I was pointing out the benchmarks to the man who thinks a 4100 destroys an i3 lol. Not recommending intel. I was saying that the 8150 with bottleneck xfired or sli'd cards compared to others on the market.

For the OP, I recommend getting a 7850 now and get another down the road. They are super fast and very power efficient.

 

[Kaylix]

Thanks guys for the replies so far. I will look into the 7850 to see if that better suits my needs.

I hope my current setup is good, perhaps if someone else has tips I will gladly hear them!

The gtx 630 wasn't the graphics card in question. It was a slower and cheaper AMD.

people around here see the words FX "Bulldozer"and instantly say SELL THAT GET A INTEL I5 HUEHUEHUEHUE...


yeah go for the 7850!!!
good luck


*btw nice set up XD

The battle of Red vs Blue continues - I myself have an FX-8150, an ASUS Sabertooth 990FX, 16 GB of Corsair, a 120 GB Intel 520 SSD and a lowly ASUS 560 and I am very happy with both my day to day usage and gaming. I fully intend to upgrade to a 670 or a 680 but I have no issues with my 8150. I am looking forward to trying Win8 on that rig once they have the release candidate - all indications are that it's going to help optimize multi-core applications/processes.

Your 990FX should work with the piledriver procs assuming they're not doing such an extensive overhaul that it requires a new socket.

I am not currently SLI'ing cards because I plan on upgrading my GPU but I usually recommend maximizing your purchase by taking the funds you were intending to use on 2 cards and purchasing a single card. Then, down the road when you feel your GPU can't handle what you're throwing at it, you can purchase a secondary card to double your processing cores. If you start with two cards, you're going to have to purchase 2 cards again down the road to exceed your current performance.

A 7870 would be more than capable of running any game you're interested in playing with ease, I am an ASUS fan for the dual-fan setup:

Thanks for your replies, very helpful. And game junky, your story makes me not regret my choices .

I agree with you about the videocard and as I found out my modxstream only has room for 1 videocard I will swithc my setup to a single card. Im in the possibility to buy a 6970 for around 200 euros. Would this be better than a 7870 and would I run into any problems with this card?

I am planning on settings up a RAID5 of SSDs when I have the cash, but at $180 each it would be a little steap. 5 SATAIII digital drives would be near instantaneous access speeds though.

No - they're fairly comparable cards spec-wise and that's actually a pretty good price. I am actually one of those weird people who like AMD procs but not their GPUs. I have an ASUS GTX 560 that is still working great until I can convince myself that I need a 670/680.
