I myself was the proud owner of a 965BE @ 4.14Ghz and while it was a great little gaming rig I didn't realize how much it did hold back even my older unlocked 6950. Before I picked up my 7xxx card I upgraded to my Intel setup and my god...I had no idea the performance gains I would get out of unleashing that 6950. I gained at least 20-30% gains at 19x12 across the board and the only changed was the proc. While I think you are plenty fine with what you have and adding in the 670 will be a nice addition, it is quite amazing how much more headroom you will gain from that card by going with a faster processor. thumb.gif Good luck and enjoy your new card!

(And those performance gains were gained at running my i5 @ 4.1Ghz as well)

Are you going to wring every last bit of performance out of a GTX 670 compared to an OC'd i5 2500k or IB? Nope. Doesn't mean you aren't going to realize a significant improvement in your games. I have a very modestly OC'd X4 980 BE (3.9 Ghz) and that's exactly my plan as well. My hardware purchases are almost always a tick-tock affair. CPU one year, GPU another year, etc... The X4 980 will do fine with the GTX 670 for another year or so and then when I do upgrade I'll get enough of a performance boost from just the CPU I'll be happy with the GTX 670 for another couple years.

Those gains were most likely from just a better CPU alone. I would imagine any work the HD 6950 was doing with the Phenom II would be the same with the i5. To say that a Phenom II @ 4.14 Ghz was holding back a year and a half old midrange card doesn't seem plausible.

(Disclaimer: This is not a jab at anyone in this thread.)

SB owners can say what they want, but a PII X4 @ 4Ghz is fast enough to shred any game out at the moment. It's good for at least 60 fps on all FPS games, and it does not hold back RTS games either. Even BF3 is easy enough on a quad core Phenom II. Your GPU is the limiting factor in that case. Obviously if you add a 2nd GPU into the mix, there's going to be an issue because there isn't enough CPU overhead to allow the cards to stretch their legs, but for a single GPU, that's simply not an issue.

An SB quad core may yield 20-30% framerate increase, but that's 20-30% over what is already a very VERY good framerate. Just keep that in mind.

As for the GTX 670, I doubt your CPU will be a noticeable bottleneck for it. You will see a framerate increase for sure.

Here is a good review comparing a 8150, 2500K and 920 powering a 7970. For most games, while the 2500K outperforms the other two, its not by a huge margin and in most games, I doubt youd ever be able to perceive the difference. There are 1 or 2 like Civilization that the 2500K is almost twice as fast and youd certainly pick up the difference here. Not sure why that game is so bad with the 920 and 8150. Weird.

Here is a review comparing them using multiple GPU's and insane resolutions. In this one, the Intel really starts to pull away, especially in the Tri-SLI configurations. But again, its only in one or two games where I think youd see the difference. AMD does stink it up on a couple like Crysis Warhead and again with Civilization but for the others, its not too far off.

Now when you think that Phenom II X4's and better are FASTER than an 8150 in games, I gotta figure that a X4 or X6 with solid overclock including NB, would still be a capable gaming processor regardless which type of configuration youre using.

Id say the bottom line is if youre building from scratch, go 2500K. If youre on an existing AMD platform like me or just hate Intel, dont lose any sleep over performance just be prepared to do some overclocking.

I wouldnt call it a "bottleneck" on anything really. To me a bottleneck is something thatll choke off a big chunk of your performance like 40-60%. An overclocked X4 wont do that when compared to a Intel. About the only place youd really see a huge difference would be at very high resolutions like 5040x1050 with mulitple GPU's. So if youre going for a tri-SLI setup on 3 1920x1080 monitors, then youre going to need an Intel powering your rig. Any single card on a single monitor 2560x1600 or below, AMD can still deliver.

Its stock is 2000 MHz but get it up to 2800 or more and you can really improve your Phenom's performance. I dont know why but for some reason, Phenom's benefit big time from an overclocked NB. My FPS in games increased notably when I bumped mine up from 2000 to 2800 and most notably the minimum fps increased. Like I said, I dont know why. Im not smart enough to give you specific reasons, I just know it works. Im on my 3rd Phenom and with every one of them, I get a BIG jump in performance when I crank up the NB.
As far as dangerous, its not so long as you use common sense with the voltage settings. Its just like overclocking anything else really. If its unstable, youll get a BSOD and you go from there. There is all kinds of info on NB overclocking on here. Look around and see what you can dig up. Its as important, if not more important when youre talking Phenoms.


Macleod has got it down pat.

 

OP, check the thread in my signature, we've got a lot of tips for performance out of Phenom II's.

 

As for bottleneck, you'll be absolutely fine.  At 3.8, you'll dust games with ease, but focusing on the NB and RAM is the way to go.  Those two are definitely the bottleneck on any computer.  NB overclocking is the same as CPU overclocking.  It'll be labeled under NB or CPU-NB in your bios and have a multiplier, usually the faster the better.  But don't loose sleep over it, I can't run more than 2650Mhz, and I handles games fine.

 

But on topic, the X4 is fine, you won't notice a difference going to an X6 or even a bulldozer.   Once you start bottlenecking, get more cards, get more screens.

 

EDIT: Also like the CPU cores, the max CPU-NB voltage is 1.55

 

EDIT2: Apparently the thread isn't in my sig, but it's stickied in the AMD section

 

EDIT3: I've got sandybridge i3 in my laptop, and my desktop annihilates it, easy 300% faster.  That being said, OP, you can blow all the money you want, but games will run smooth and your AMD setup, or an Intel setup.  You'll only notice a difference in synthetic benchmarks.  Which you aren't going to impress girls with.

Lol. Well I'm willing to drop 500 bucks? So after the 670 what would be a significant upgrade cpu wise using the same mobo or would I have to have an entirely new motherboard?

Thank you for all the replies guys.

I will start overclocking the NB when I have the time, thank you. I'm trying to get the most out of my phenom because I didn't know I could do all this before and never took the effort to.

Thats hard to say really. I honestly believe that the Thuban's are a little better than the Deneb processors. If you could find a 1090 or 1100, that would be best. If not, pick up a 960T which is a 4 core Thuban. I dont know if youre gonna be able to find any Phenom's though. Theyre getting pretty scarce. Dont sweat it too much though cause your 965 can get the job done. Just get to work on overclocking that sucker and you should be ok.

If you want to go so far as to get a new motherboard, might as well go all the way and get the Intel since it would cost about the same and youll have to reinstall your OS anyway.

I say just get the 670 and overclock the guts out of your 965 and see how it goes. Compare it to other benchmarks you see on review sites. If you can match or come very close to the results posted with them using high end procs, then youre fine. If you see that youre way off then we can figure something out then but I think youll be fine with your 965.

I know PII 955 @ 4.2Ghz is about at its limit in BF3 with GTX470 @ 880Mhz. You will get more fps for sure in part of the game where GPU is more impartand but in average you will need to get a faster CPU. You could probably pick up a 2500K very soon with MB and RAM for ~ $250.

Again we're talking MINIMUM FPS HERE.

If you game AMD, you'll be probably be upset when you constantly drop to 30 FPS (or lower) from 90+. For me, it completely ruins the gaming experience and it counter productive to the rig I had intended to build.

I don't experience the kind of drops you're talking about. BF3 fps is pretty consistently above 60 and drops to 45-50 if I do something like look across the entire map from the edge. I dont think I ever drop below 40fps in any game actually. Do you overclock?
