Hey there everyone,
my current rig is as follows:

Q9550 @ 4.0 GHZ
2 Sapphire 4890 Toxic Editions (overclocked to Atomic speeds)
Gigabyte EP45-UD3P motherboard
4x2 gig sticks of RAM

My question is a simple one - is my Q9550 bottlenecking the 2 4890's (which are running at 8x PCI-e 2.0 speeds)? Would it be worthwhile to upgrade to Core i7?

My primary use for this computer is gaming - I spend about 70% of it's use gaming. However, I also do a lot of video editing and photoshop work for my job on it. I have some cash to spend and I was thinking of buying an X48 motherboard and a larger monitor (with a 1080P or higher resolution), but I'm curious if the Q9550 is bottlenecking my system (at stock clocks or overclocked to 4.0 ghz).

Thanks!

is your OC CPU bottle-necking your GPU....maybe a tad
should you upgrade....no

Thanks for the reply,
do you think it'd be worthwhile to get an X48 motherboard so that the two 4890's would run at true x16 pci-e 2.0 speeds, or no?

worthwhile? probably but I would hold off if your system is giving you very good gaming results....which it should

Well it's giving pretty good results, I get a constant 300 FPS in all source games (which is totally unnecessary but hey it's nice :P), however with games such as GTA4 or Cryostasis or ArmA II, or Far Cry 2, my FPS drops to 30-35 fairly often (GTA4 sometimes drops to 20's!).. Which is still good, but seems out of place with 2 4890's in crossfire. Is that normal?

what resolution and AA settings?

GTA4 is the worst console to PC port out there

1680x1050, but there is no setting for AA in GTA4 (something to do with the rendering engine doesn't support AA, or something silly).

Like I mentioned earlier though I'm thinking of upgrading to a >1080P resolution, so I'm kinda scared for my frames :/

then you may want to look into that X48 board

Yes, it is bottleknecking your GPUs, but the gameplay is fine. Check out this review that I keep posting for these same questions. http://www.guru3d.com/article/core [...] e-review/7

This thread is so wrong.

OP, do not confuse a bottleneck with a cpu limitation.

If you feel you are getting unplayable fps and it is due to your cpu then test it.

Run the games at lowest gfx settings and a low resolution and see if you still get unplayable fps.

If however, you get playable fps then there is no point in upgrading as you won't notice the increase in fps if there is any.

GTA and cryostasis are not good things to judge your system by as they are known as badly made. ArmaII as far as I know is not crossfire enabled and is mostly gpu limited from my testing anyway.

The above posted review is off, way off, not only incomparable processors but it is ancient and mixes up so many gpu arrangements it can't be used to compare anything.

Seriously though, don't go wasting money you don't need to, test how many fps your cpu can output, then see how many fps you get at max graphical settings, if the fps doesn't change and the fps is unacceptable, then you could do with an upgrade, however, I would very much doubt it.

The above review shows different processors with the SAME GPUs in different arrangements. Did you actually read it or just click on it then close the window? It shows an E8400, Q9770, and an i7 965. It demonstrates that dual cores, which were great for games in the past, may not be the best way to go now if the budget allows. A Q9770 and i7 965 are clocked at the some frequency and you can see the CPU limitation get larger as more cards are added to the system. I don't see how the review is "off, way off" when the author wanted to show the benefit of i7 and X58 with multicard setups. Even if the E8400 was overclocked, it wouldn't have come close to overcoming the i7 advantage with many cards. I think you should reread the article then comment again, no disrespect.

No where does that have anything to do with bottlenecking.

It use 8.10 drivers for crying out loud.

When doing tests you need to limit the variables as much as possible, using a dual core and two quad cores with varying gpu's shows nothing of any value to the OP.

It is a useless review in context of the OP's post

Simply put, it is ludicrous that people fling the word bottlenecking about when using a 4ghz Q9 series cpu.

Heres a couple more pertinent, and compatible reviews showing cpu limitations
http://www.legionhardware.com/docu [...] id=807&p=4
http://www.behardware.com/articles [...] ition.html
Same card, different cpus, but, as each cpu is brought to higher clocks, the 295 keeps on going, even the top i7 at stock showed higher results.
This is mainly Crysis, but WiC is there as well.
I know theyre mixing cpus here, and as long as its the same basic platform (mobo,ram etc), you can get a glimpse of each gen and or family of cpus at what clocks the improvements bring, if any.
Seeing comparitive 295 vs 4890cf'd in a couple of reviews, theyre very similar, and should help the OP somewhat here

A cpu limitation is one thing, a bottleneck is another and I don't think the OP will really notice a difference.

Hate to be a git about this but common sense should be applied here.

Can I suggest you do a disck cleanup, defrag and update the graphics drivers properly?

Also have you tried manually messing with the graphics settings for the PCI-E bus?

might give you some return for the time.

Also shtdown all other processes not central to your gaming experience.

Try Hyjackthis which is a nifty little program to make sure nothing is running in the background and chewing up cpu cycles.

Switch off the AVirus program when seriously gaming.

Get rid of all unwanted distractions other than the cola and chips etc ... women, parents all need to be moved out of the area ... dosconnect the phone and tunr of the cell.

Now your ready ... resume gaming.

Hey thanks for the replies everyone!
What is the difference between a CPU bottleneck and limitation? Isn't a CPU that's bottlenecking performance, in essence, a CPU limitation?

Basically my end question is this: with two highly overclocked 4890's in Crossfire, would I see substantial boost in game performance (I don't care about synthetic benchmarks) by upgrading to LGA 1336/Core i7/tri channel DDR3?

Price isn't really an issue here as I have a high paying job and a decent amount of disposable income (and I don't mind saving for my toys :) ). I just want to know if statistically-speaking I'd see short term/long term benefits in my gaming.

(Also keep in mind my current board, a P45 chipset, runs my CF'd 4890's at x8 speed. Although I thought I read somewhere that no current GPU's tax the bandwidth availability of x8 2.0 sockets, much less x16).

This comes down to preference more than anything, every system is limited by something depending on application being used so saying something is bottlenecked because of a normal limitation is wrong IMO.

A bootleneck bring to mind in a lot of people a drastic reduction in possible performance when really, as long as your game is playable or application usable a limitation does not matter because you don't see it.

I just don't like people thinking they have to spend money on components they don't need. Games really haven't changed that much in the last couple of years(correct me if i'm wrong) and speeds like you are using were unheard of yet people weren't complaining of bottlenecks then.

Just my opinion of course but the higher performing components you can get the more systems become "bottlenecked". Doesn't make much sense when you can't see this bottleneck without the use of fraps or something.

Yeah I totally agree strangestranger - I wouldn't have ever even brought it up if I wasn't seeing peculiar performance in games that I'd figure my rig would dominate. It just seems fishy to me that I can dip into the mid-low 30's with two 4890's and a highly overclocked Q9550 in some modern games. :O

Although the games I play the most (Source engine based titles) you could probably get working on a calculator, so I have no problem there... Haha
