How much will a Athlon ii x4 630 bottleneck an amd 6950?

Just bought a new GPU, RAM and PSU to upgrade my older hp desktop:

I have a Athlon ii x4 630, 2.8 ghz processor and I bought:

Sapphire 2gb 6950 http://www.newegg.com/Product/Prod [...] 6814102987
8 gb ram http://www.newegg.com/Product/Prod [...] 6820231426
and a 750w PSU http://www.newegg.com/Product/Prod [...] 6817371051

I figured my CPU would limit this setup, but how much? I can't overclock because this is a pre-built machine, but if need be I can buy a better AM3 CPU like a phenom x4 965-980. I have just put this off until after I see how my current rig performs with the new stuff, which is still in the mail. Any idea how much of a bottleneck this will be?

Thanks guys.

  1. The major difference between Athlon IIs and Phenom IIs is the L3 cache?
    Does L3 cache affect gaming performance? In most cases yes, you might find 20% boost in FPS using a Phenom II CPU clocked the same as Athlon II but has a high L3 cache, so basically it will make a difference if you're playing a game and in the sake of 15-20 FPS more, and bear in mind the RPG games are very CPU intensive games, lower resolution depends more on CPU power.

    Phenom II X4 980 BE is a gaming monster, I'd go for it.
  2. not as much as with a 670 :(
  3. Thanks for the advice so far guys.

    I'm hoping to play bf3 on some high settings. Currently, I'm rolling on a gts 250 with everything set at low. I forget what FPS i'm playing at, but its not impressive. Still I enjoy the game. Hopefully the new GPU will make a huge difference and won't be hamstrung by the CPU. I hear BF3 is GPU intensive. Any other thoughts guys?
  4. What resolution are you on?
    Yes it's GPU intensive game.

    HD 6950 is able to get you a very playable FPS @ ultra 1080P, with your current CPU it won't make a difference compared to a Phenom II X4, but in other games there' will be a huge difference.

    So right now, you can play BF3 without no problem, you should get 40+ FPS.
    But you gotta upgrade that CPU soon. X4 980 BE is the most powerful gaming CPU in the phenom II series.
  7. Depending on the game, yes your CPU will hold you back as others have mentioned. As far as upgrading goes I would still get the 6950 and when you get the money or feel the need to upgrade the CPU you have a pretty solid rig instead of a low/mid-range GPU.

    It's how I upgrade usually. Upgrade the GPU first and then once the CPU is holding me back upgrade the CPU and on and on....
  8. You could try overclocking if you're worried about bottlenecks. You should be able to get 3.5 ish if you have a good motherboard. You can't up the multiplier with Athlon iis you have to OC with the FSB.

    depends on the game, for most games the 980 will win out. very few games use more then three cores, even modern games.
