CPU bottlenecking my GX2?

post #1 of 27
Thread Starter 
I am going to quickly assume so, but before I go and buy an E8400 I thought I would get some input from you guys.

Well, I am using a rather junky E6300. Junky in the sense that my GX2 isn't pulling the kind of FPS that I want in Crysis. I have seen plenty of people using the E8400 and a GX2 and pulling 65+ FPS on high settings, but at best I'm getting a 55 FPS average. Granted, it is certainly performing better than my GTS 512 ever did, but I am seeing those with newer CPUs pulling much better frames from Crysis.

Is this the obvious culprit, or am I just cursed with low FPS in a game that I have been striving to get 70+ FPS with? I get 14.2k in 3Dmark06, and my GTS 512 got 13k. That's another reason why I'm thinking that my POS E6300 is holding me back. Should I just slap down $200 for an E8400 (after I have already slapped down 120 for a new PSU and another good chunk for a 500 gig SATA)? My mobo definitely supports it, so there's no issues there.

Quad core will get the jobe done.
with GX2 you should score atleast 18k on 3dmark06.

It's not about benchmarking, it's about framerates in a game.

Frankly, 55 FPS in Crysis is good if you aren't getting any stuttering. I mean, it's Crysis. Seeing that monitor in your sig, I assume you run 1680x1050, and 55 FPS is pretty good for that res. Don't expect much, it's not even as fast as GTS 512 SLI.

It seriously doubt it's the cpu, myself, especially if you're relying on the GPU benchmark to indicate the FPS you're reporting above.

Here's an easy way to tell ... downclock your cpu about .3GHz and see if your score goes down further. If it doesn't (and again, I suspect it will not) then you'll know for a fact it ain't the cpu.

The reason I seriously doubt it's the cpu is two-fold. If you check the benchmarks forum (where many of our benchmark results are posted on a bunch of different settings in a thread started by LordIkon) you'll see *very* little correlation between cpu clock speeds and scores. It's certainly nothing remotely like the correlation you see in 3dMark06. What you see is a dependency on GPU and gpu clocks, pretty exclusively.

Reason 2 is that when I run the benchmark at 800x600, all low, I'm able to pull off nearly 160fps. That should mean that your cpu is capable of running Crysis at well over 100fps. Therefore, it should not be the bottleneck at the fps speeds you're talking about.

And yes, your CPU *IS* holding you back in '06. But that doesn't mean it'll hold you back in games, which you play with much higher IQ settings/resolutions than you have on that benchmark. Not to mention, it actually *tests* your cpu and counts it in the score, so ...

Actually, you gotta look at an identical setup to say that. I used to own a GTS 512 and it did pretty good while I'm using my E6300, but the bottleneck seems to be getting worse in comparison with this new card. It does beat a GTS SLI setup if using my same hardware.

I'm sure the CPU is a severe bottleneck because when playing Crysis, especially online, it's not uncommon for my CPU to be under 100% load, causing the game to be unplayable. This happened with my GTS 512 installed too, so it's not the GX2 causing that.

I just decided to go ahead and get the E8400. It's available at the place I'm getting it, so I might as well while they have it in stock. It's time for a better CPU anyway. Not that my E6300 hasn't served me well, but it is an aging CPU and I have a mobo that supports dual and quad 45nm CPUs.
