i7 2600k vs AMD 955 Black (Stock) in Battlefield 3 - Page 2

post #11 of 26
An overclocked 955 should abolish your bottleneck greatly, if you feel there is one, though with a CPU like the i7 2600k you won't have to work about bottleneck for a very long time, even at stock.

I'd suggest staying single GPU for a while and getting the 2600k just to avoid annoying possible SLI troubles.. my 2cents

The CPU was not his problem there.

of course I did my homework. similar setups like FX4100 @ 4.8ghz, Phenom II 955's at 3.8ghz was bottlenecking as well. it convinced me it was a cpu bottleneck. switching to 1055t fixed it for him. he hardly spend much because we got a used 1055T and sold his 955BE as well. I just wanted to share my exp. I'm just sharing my personal exp tongue.gif believe me i'm not spreading BS hehe

luckily we got a good clocking 1055T. was a little worried overclocking at a 4+1 power phase gigabye board. it had heatsinks on the vrm's so I still overclocked on it. got 4ghz very easily with only 1.425v. I told him to run prime overnight and it was stable for 12 hours smile.gif

^ this.

with a single 560 Ti I wouldn't worry about bottlenecking. but as the Op said he's considering getting another gtx 560 Ti. imo a phenom II 955 is still enough. although I'm not sure if it will be enough for BF3

I never saw BF3 max out a 6 core cpu thou but maybe memory handling of a thuban helps or even the ever changing speed of the cpu helps things.

He has said that a new CPU + MB is not a viable option.

Why does every thread end in someone recommending a SB processor, even where a new processor is no required.

There will be a minimal bottleneck with 2 560ti's if you overclock your processor, maybe 10-15% at the most.

They are solid cards and when the time comes, they can always be put into a new rig with a new CPU. But right now, a 955 is absolutely fine for any game out there.

SLI is fairly faultless now. Ive only ever had a few driver issues that were easily solved.

I think it's the coding of the game. the 1055t maxed out the 6870's really easily also with low cpu loads. if you do the math it doesn't make any sense. surely a similar cpu minus two cores should be enough but alas it wasn't.

haven't really tried BF3 on my htpc (phenom II 955 @ 3.6ghz and gtx 470 overclocked) very similar to the op's system. I might install it just for this. although dealing with origin is a pain frown.gif

no one is really saying a phenom II 955 is not enough for 560 Ti SLI. personally I'm making an exception with BF3. I really hope I'm wrong. maybe an update to the game will fix this. I couldn't fix it with my friend's system. although upgrading to a 1055T fixed it completely

With a single card, the 955BE is just fine. I have an unlocked 555 and at 3.2ghz, I don't get any CPU bottleneck at 1920x1080.

If you are doing CF/SLI you may want to overclock it some or look into a 1090t though. But BF3 has been proven that CPU brand doesn't mean much with a single card and when you turn the graphics up. It likes cores and speed, not brand name.

And as i have just said, i have just run some tests on BF3 with my 955 and get 99% GPU usage on SLI460's. The bottleneck will be minimal, if it exists at all. thumb.gif

Your system or same cpu + 6850/70CF is a well balanced rig anyway. If you had 6950/70s or 570/580s thou, you wouldn't get much improvement on crowded scenes alas Min FPS biggrin.gif
