AMD FX Bottlenecking

Hello,
I'm going to buy a pc but i was just wondering would this setup work good? Later on i would be planning on upgrading to two 680's but if the cpu would bottleneck the cards to much, what about with a 670 in sli? If there was a bottleneck issue would overclocking the CPU fix any of these problems?

CPU - AMD FX 6300 Six-Core - AM3+
GPU - Gigabyte nVidia GTX 680 2GB OC
RAM - Corsair 8GB (2x4GB) DDR3 1600MHz CL9 Vengeance
PSU - XFX ProSeries 850W Core Edition 80+ Bronze
Motherboard - Gigabyte GA-970A-D3 Mainboard - AM3+
HDD - 1TB Western Digital Caviar Black Hard Drive

Thanks.

More about bottlenecking
  1. Either cards in SLI will be a major bottnecked by the CPU. Even the single cards will be bottlenecked a little if it is a cpu intensive game. Look at these benchmarks (they use a gtx 680):

    I recommend getting an intel i5 3570k instead if you plan on using 2 cards.

    Even with overclocking? If not, what cpu would you reccomend instead?

    I updated the post if you didnt see it. The intel i5 3570k is a good choice and wont bottlenack anything. Of course you would need to choose a new motherboard. Also the motherboard you chose in your original build would not work for SLI anyways. It only supports 4x speeds when both of the pci-e slots are in use.

    i was looking at that but it stretches my budget a bit, any other amd cpus that would bottleneck but are yet at a reasonable price?
  5. personally i would rather get the i5-3570k + a gtx 670 instead of a fx 6300 + gtx 680

    you can overclock the 670 to come close to the performance of a 680 stock speed

    Nope If you looked at the bench mark even the FX-8320 bottlenecks some games quite a bit. Instead of getting a gtx 680, get a 670 instead. Then put that money towards the intel cpu and motherboard. If you are planning on running SLI, make sure you choose a motherboard that can run at least (8x/8x) speeds when both pci-e slots are used otherwise you will see a bottleneck from your motherboard.

    A question though, you are using the computer for gaming mainly right? Some programs like photoshop run well on the AMD cpus because of the high core counts.

    I Will be doing mainly gaming but also some video edits and photo edits in after affects and photoshop. but mostly gaming. would this motherboard be good? ASRock Z77 Pro4 Intel Mainboard - LGA 1155
    1 x PCI Express 3.0 x16 slot (PCIE2: x16 mode)
    - 1 x PCI Express 2.0 x16 slot (PCIE3: x4 mode)
    - 1 x PCI Express 2.0 x1 slot
    - 3 x PCI slots

    Yes then the intel 3570k will be your best choice. Photoshop and video editing runs well on these programs too. Better than the AMD cpus.

    If you don't plan on overclocking, heres a cheaper version of the i5.

    Nah not good if you want to SLI. only the first port will be running at full bandwidth. Your second one will run at 4x.

    Try this one instead.

    http://www.newegg.com/Product/Product.aspx?Item=N82E16813131837

    Its $120 after rebate and coupon. Free shipping too! so its only a few bucks more in the end
  10. http://www.centrecom.com.au/catalog/z77x-gigabyte-z77x-intel-mainboard-1155-p-57270.html?sort=3a would this motherboard still be alright? the first gpu would be at full speed and the second would be at 8x
    1 x PCI Express x16 slot, running at x16 (PCIEX16)
    (The PCIEX16 slot conforms to PCI Express 3.0 standard.)
    * For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
    * The PCI Express x16 slot supports up to PCI Express 2.0 standard when an Intel 32nm (Sandy Bridge) CPU is installed.
    1 x PCI Express x16 slot, running at x8 (PCIEX8)
    * The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot will operate at up to x8 mode.
  11. ok here, this is my story

    so i had the fx-8120 overclocked to 4.7ghz! and I had about a 30-40% bottleneck in bf3 with my single gtx 670... I then upgraded my system to the i5-3570k and a z77-extreme6 motherboard(recommend it by the way I really like it so far and has two 16x pci-e slots) and I now have no bottleneck(some at times but from what i dont know because i CPU does not his 100% usage at these times so i dont know...

    anyways after installing the i5-3570k i relized that my 8120 was throttling so it went from 4.7 to 3.2 to 4.4 to etc etc it was crazy... I do not regret my purchase because i mostly only game and the 3570k alone with no overclock is about 30% faster or even more than teh 8120.... basically though make sure to see if your cpu is throttlin what you want to do is open core temp and run and cpu stress test if the CPU's speed goes around weirdly then you are throttling and im sure there is an answer, just check this and keep me posted

    also the 6300 will be better than a i5 with video editing though not with gaming if you want cpu that is great in both get a i7-2600k or i7-3770k

    Hope this helps :D
  12. get this motherbaord
    http://www.newegg.com/Product/Product.aspx?Item=N82E16813157295
    it has great features looks nice and has two 16x pci-e slots so it will suite your needs indefinitely

    How about this? its basically the same motherboard with the same amount of pci slots at the same speed, but its cheaper and on a different site.
  14. sure if you want then sure, the only thing that the extreme6 has is more features for overclocking but if you are not an insane overclocker then sure the extreme4 will work just fine as well

    Actually they both run on 8x when both slots are used.

    Yep loooks good to me. You still need a hard drive and RAM though. I recommend 8gb of RAM. Consider a small SSD (~64gb) if you have the budget for it. Very nice to put the OS on it and a few games. The boot times and load times will decrease by a lot. Good luck!

    there is this motherboard for $15 cheaper but basically the same features with less over clocking support but i can still oc a little bit. i already have a spare hdd and the 8gb of ram but the ram is just your basic 1600mhz 8gb. i have windows home premium 64bit with quite a few games

    No i live in australia wich causes conflict in online stores but i think i found the same version but from a local retailer http://www.centrecom.com.au/catalo [...] ml?sort=3a
  21. I like your build, the extreme4 when both sli run on 16x get your facts straight @cracker

    as for the build I like it, though i would recommend going with a trusted PSU brand like corsair and also to get an ssd(only if teh load times matter it wont increase FPS really at all) and to get 8gbs of ram at 1866 get the g.skill sniper 1866 version

    Um its a high speed drive with 64mb of cache so it will be faster than just a normal 7400rpm but i dont really see the point in ssd untill they go up in capacity and down in price. the ram i have is capable of being overclocked to that speed so thats something i will do. um for Australia that is one of the most trusted brands its reliable and it comes with a large warranty, so there isnt much of a problem there
  23. ok be careful when overclocking your ram, i tried once and my computer refused to post... you just need to reset your bios but it is scary :P

    haha yeah ill remember that,
  25. Best answer
    I own a amd 6300 overclocked to 4.5ghz and a 7970ghz.

    At stock clocks the 6300 bottlenecked my 7970ghz a bit. 75% gpu usage on battlefield 3 However once i overclocked it went away. Do not. i repeat. DO NOT get any high end sli/crossfire build with Amd cpus. i own one i KNOW. If it bottlenecked a single 7970ghz
    and i had to overclock it to get rid of it. imagine what it would to 2 7970s/680s.

    If you were going with a single 680 id be like yea sure just make sure your overclocking.

    If you dont have the money for 2 680s+i5 3570k. get 2 670s.

    Im not hating on amd. I wanted to support there cpus. And help them out in a rough time. But for someone like you i cannot recommended them. But as i see you choose the i5 3570.

    Just wanted give you some assurance that you made the right choice. Gooday.
  26. oh my god, two 670 is really no different from two 680's they are only 5% less powerfull

    also yeah AMD cpus are just not good for gaming i owned one for 9 months and had a load of bottlenecking

    Yea 670s a great cards. 680s are not worth the price difference

    Yea amd cpus are pretty meh... at stock clocks it wasnt impresive my 6300 but when overclocked its pretty good. but still Having to overclock your cpu to not make it bottleneck your card is pretty dumb esspically since there both new products
  28. yeah, agreed
  29. well i have a fx 6300 with a single gtx 680 and I found wiht the right psu (corsair cx750) I experienced a quality rig. I am buying from uk and got fx 6300 for £90 and gtx 680 for £245 a deal as I thought, but it was not untill i got really good psu that I seen full benifit. BF4 runs amazing at 60 fps, good enough for me btw I have 8GB 1333mhz ram which is shit but I still enjoy the game running great frames. also i have an M5a97 mobo which I would recommend.all in all I want to help people trying there best on a budget to game well and this worked for me. btw this can be overclock to ur gratification compared to an expensive intel buy. I hope this helps the guys in a budget. GET CORSAIR PSU!!!!!

    js, this thread is solved and was last updated 10 months ago.
  31. just to day, when i got the 3570k my fps went up dramatically and the 3570k can even handle 670 sli no problem... so just wanted to add that
