Pentium D bottlenecking 8800 GTS 640MB

hi i'm using a Pentium D 2.8Ghz processor which is greatly bottlenecking my 8800 GTS 640mb...............can anyone suggest me a cheap processor which could compleatly remove the bottlenecking.

i play games like Gears of war, Rainbow 6 vages....................which face a lot of bottlenecking during game play.


my config is

processor--------intel Pentium D 2.8ghz
RAM---------------3GB ddr2 800mhz
motherboard----DQ965GF
GPU---------------nvidia 8800 GTS 640MB
smps--------------500W
cabinet-----------antibiotic zeberonics
hard disk---------160GB segate
Sound card-------creative sound blaster audigy

  1. should i get a core 2 duo processor..........if so which is the cheapest one which could remove the bottlenecking.
  2. You can go to 3.2 GHz if you overclock the FSB and you should see an improvement in your frame rates and also pretty much max out your videocard's capability. However, that's a CPU that runs hot so you'll need to monitor your temps or get a better cooler.

    But now looking at your motherboard, I'm not familiar with it as far as its overclocking ability. Hmm... if it doesn't let you tweak the FSB, a faster processor won't help much and neither will replacing your videocard with even a GTX 260.

    If you want to upgarde cheap, you can try this G31 chipset motherboard with some overclcoking ability.

    You can use your old components and overclock your Pentium D 2.8 to 3.2 GHz or maybe 3.7GHz if your CPU can stay cool. Then later, you can use this motherboard for an e7400 or even e8400 and a GTX 260.
  3. Depending on your budget, upgrades can range from CPU only to many parts. If you do have a tight budget, you can either get a better air cooler and overclock it or you can upgrade to a dual core E5xxx. However, if u have a loose budget, you can try AMD tri-core or the quads. It all comes down to your budget.
  4. Ideally, an e8400 would remove the bottleneck and would push your videocard to give all that it can. But I'm not sure that even with the latest BIOS your motherboard can support a 1333 FSB? You'll have to research your board revision and the BIOS upgrades to see if that is an option.

    If not, then I don't think an e7500 at 2.93 for $139 is worth the upgrade when you can get a new motherboard for $50 and use your current CPU to run at 3.2 GHz on a faster bus.
  5. A lot depends on where you are, so, where are you?
    Probably you will have to replace the motherboard to get any decent overclocking done, Intel boards are stable and good quality but not really built for the overclocker.
    Here is a link to the Intel site showing their official CPU support:

  6. well i dont intend on overclocking..................................so my final decision is to replace the dual core pentium(R) D 2.8ghz 820 with the core 2 duo E7400 2.8ghz which costs about Rupees 6k here in india..........................but still can anyone still suggenst some other cheaper processor which does not bottleneck the 8800gtx 640MB..........
  7. any of the new E5XXX series from intel will out perform your current CPU and not bottle neck your card. you would need to do some research to see if your motherboard will operate with them.
  8. Your original proc was a Dual core Pentium @ 2.8 and your experiencing bottle necking?
    What resolution are you running and what games are you playing?
    Im running a AMD Opteron 165 @2.4 with 2 gigs of ram and I'm running titles like Lost Planet at 1600x1200 maxed with no problems.
    Crysis is about the only thing I cant run completely maxed and even that runs well on my system with high settings.
    You should try reinstalling your OS clean with all the latest drivers then tweak and optimize all your settings.
    If your using an on board sound card you should try disabling it and install a half decent PCI card...a sound card can be the ultimate bottleneck when your machine is at the top end of its performance envelope.


    processor--------AMD Opteron @2.4
    RAM---------------2GB ddr2 800mhz

    He didn't say he has a Pentium Dual Core he said Pentium D. As in 2 P4s on one die. They're crap.
  10. ^ Right. edeawillrule is right, I don't think he has any of the newer Pentium Dual Core CPUs (i,e E5xxx) but a Pentium D which is older and slow than a Pentium Dual Core at similar clock speeds.
  11. so u guys are telling me that the dual core E5xxx series will stop bottlenecking my gts 640mb.

    thanks guys coz dual core E5200 2.5Ghz costs only 3.5k here in india.......so now i can save half the price.
  12. let me ask a question related to this one, im using a stock e4600 with 4gb ddr2 800 (2x2) and a 9800gt 1gb.

    does my proc bottleneck my vc?

    Yes is the answer. If you want to know what kind of performance you're missing and your motherboard allows it, firts run benchmarks on stock settings, then overclock your FSB from 800 to 1066. your CPU will then be at 3.1 GHz and your benchmarks will improve, meaning your videocard is finally pumping out texels the way it was designed to do.
  14. Wait before you buy anything...is your card connected by a PCI EXPRESS 16 SLOT???? This is very important!

    Of course it is! The last Nvidia card made for AGP was the 7800 GS!
  16. ^...what is your point?
    Anyway I need to know wether your card is connect by pci express 16 slot or pci express 2.0. They are very different connections and if you card is connected through the original pci express slot then i am not sure but it could possibly be bottlenecking your card.
  17. The PCIe 1.0 card slot will run PCIe 2.0 GPUs.

    Theres a test on this sire on which they ran a 9800 GX2 on PCIe 2 x8, x4 and x1. x8 is equivalent to PCIe 1 x16. No drop on performance in Crysis upto x4.Only Flight Simulator X showed a drop. Of 2 9800's run fine on a single PCIe 1 slot, there no way a single 9800/8800 be bottlenecked by the slot.
  19. hmmm alright, i guess you are right..thats why i said i wasn't sure.
  20. by the way one last question will the E5200 work with my motherboard

    MOTHERBOARD is : intel DQ965GF
  21. http://www-dr.cps.intel.com/support/motherboards/desktop/dq965gf/sb/CS-025970.htm


    http://processormatch.intel.com/COMPDB/SearchResult.aspx?Boardname=dq965gf

    Not listed as a supported processor.
  22. your right

    but do u think a bios update can enable the DQ965 to support the E5200
  23. You will have to ask Intel that question. Some older motherboards chipsets will not support a 45 nm CPU even with the latest BIOS.

    From what I've read, no it will not support the e5200. But I could be wrong. Because I haven't found anything to say it does support the e5200 doesn't mean someoen is using that CPU on that motherboard.

    I believe the D's are 2 cores on 2 dies, whereas the Dual Cores are 2 cores on 1 die.

    @others,
    if he can get a mobo cheap, then he should do so. If he can get a E7400 for 6000k rupees (~$120 USD) he should go for it. So CPU + mobo are the best options. Or just get a 65nm Core2Duo or Core2Quad that is supported by his current mobo.
