Hd 7750 bottleneck

i Have core 2 duo e6750 @ 2.66GHz
6gigs ddr2 ram ______ _____
Stock HP PSU wit 365w 12v-------- 12a 12v (CPU) ------- 14.5 a

And will buy HD 7750 to play bf3 online medium to high 1280 x 1024 or 720p on low to medium to high settings so will i get about ~40 FPS?

And HD 7750 cant reach its full capacity due pcie x16 1.0 or pcie x 16 has enough bandwidth rate for hd 7750?

will it bottleneck
will also play black ops 2 720p low-medium

More about 7750 bottleneck
  1. I have the E8300, a little more powerful then the E6750 set up with a 7750. On 64 player servers, bf3, cpu is pretty much flat out 100% and 7750 is at like 60-70% @ low preset 1680 x 1050 25 fps.

    so yes your cpu will bottleneck the card in bf3 multiplayer but it should be fine for non-cpu intensive games :)

    The card is being used with with a GAG41M-COMBO which has pci-e gen 1.1, no problems
  2. the cpu will bottleneck, however if you can find the money, upgrading to a core 2 quad should help rectify that
  3. bout how much fps will i get on BF3 MP 720p low all
  4. you will likely not get any higher fps due to cpu bottleneck

    I run a 5650m and a pehnom IIx4 2ghz in CSS and in 64 man servers, my cpu gets maxed but my GPU load is only 15% for high settings and 4xMSAA 16xAF 768p

    If you're not being bottle necked, expect performance up to maybe 50% higher (maybe even more) than these ones since this is with old drivers and at a higher resolution than you and ultra settings

  5. the are of multiplayer or singleplayer? also ultra settings or high or low?
  6. In single player you will get 40fps at high or ultra but in multiplayer it will strugle
  7. can i play low 720p on multiplayer?
  8. Yes but there can be more bottleneck due to low resolution and low settings as it shifts the power from gpu to cpu.mostly you will be fine do not worry much about bottleneck.
  9. Ashish65 my cpu is about same as yours so can u see ur FPS on these settings low on 1280x1024 64 player map
    i mean i just want 40+ fps cuz 720p low(only multiplayer) is also a good graphic and will buy core 2 quad after 3-4 months
  10. See at 1368*768 at high settings(vsync and AA to off) i get 40 fps in multiplayer so your resolution is slight bigger than me so assume -4 fps and your core 2 duo is old cpu and it not same as me as they are different architecture so -10fps so you will get around 25fps at high.
  11. In single player i get 60fps easily at ultra settings with vsync to on and AA to off.
  12. vsync stops fps increasing from 60 fps decreasing bottleneck?

    online ill get bout 35-40?
    ofcourse low settings
  13. also i have old HDD and ddr2 ram that will effect too?
  14. In multiplayer BF3 it really won't matter what settings you are running at you should get about the same FPS either way... Due to your CPU bottlenecking your fps to something like 20-25 FPS... It won't be so bad with less people on the map - so you might have to just stick to smaller games to have it playable.'

    Edit: Or upgrade your CPU.
  15. if you're using a 1155 board you can upgrade to a i5 3470 if you have the moeny or just a i3 3220 to remove some cpu bottleneck

    with high settings it will be 25-30fps,at medium-high may be 35-40fps.

    do not turn ever to low settings = more bottleneck

    there will be no bottleneck hd 7750 in pci 1.0

    see here - even high end gpu loses 5% performance loss.no measurable difference @ pci x16 :D

  18. do not worry dude go with hd 7750.there will be only bottleneck in multiplayer games like bf3 but you will get playable fps.on other games you will easily get 40-60fps at high.
  19. playable means 30-40?
    And dude after researching i saw that
    Intel Pentium D 2.8Ghz ( which i had but sold to get the core 2 duo silly me )
    is better than core 2 duo in gaming.
    is that right..
    i sold whole CPU 40$ and boought core 2 duo dc 7800 hd for 300$
  20. No pentium d sucks.your cpu is far better than as new architexture + more cache.do not judge cpu according to clock speed.
  21. ok bro
  22. ASHISH65
    u have been helpfull the most bro really but to tell my by installing windows 8 from xp my moniter could display 1080p graphics ow yea
    so 1080p low preset hd 7750 online will be playable? cuz less bottleneck as more will be on gpu right
  23. Yes it will be playable
  24. also bro
    1280x1024 has more pixels than 1368x768
    large amount so u get 40 fps online on high i will get 30 on high cuz of cpu

    and that of changing my montitor ressoultion to 1080p was a bug and viewsonic told it might damage hardware cuz i bug with hv frequency over range ( loled when i got 1080p on 2005 model moniter 17" )
  25. Yes you resolution has more pixels
  26. but before u said i get 40 fps but due to ur resolution -4 fps
    was it wrong? or it still applies
  27. You resolution is big so more pixels so fps will decrease so it would be -4 so 36-37 fps like at 1280*720p i get 70fps but when it change to 1368*768 then it slides to 58fps.
  28. hmm more resolution = less fps
    more high settings = less bottleneck
    so at 720p ill get 60fps and online 35-40fps
    thanks bro buying the card tommorow u have been helpfull the most
    btw club 3d is good? it provides game also as well as 5-15-20$cheap than other companies as well as 2 years warranty

  30. It is good to buy from club 3d.i suggest you after getting the gpu please post some game results like fps with settings in games like bf3,crysis,nfs ...etc so that it might helpful to others.
  31. i bought club 3d and getting solid 35-40fps online 720p high
    altough amazing graphics on 720p

    iam getting 55-60fps high singleplayer
    does not go below 30 nor above 65
    singleplayer does not below 35


    are these good with my specs
    will my friend also get these fps with same setup?
  32. Really great fps.your friend will get same please test other games also
  33. i burnt my card by overclocking :( shop says overcloking is ur own risk and they cant return it so i threw it in the bin.......

    what?!! Why you overclocked?
  35. i had few stutterring in game like 1 in a minute and stutter was like 1-2 secs long to fix that i OC'ed and failed
  36. Really its heartbreaking
  37. i know dude u really helped me configure which is good graphic card but what has to happen has to happen , i am getting a i5 or i7 rig within 6 months.
    HD 7750 was a good card if i lowered my setting it wont stutter but.....
