bottle neck ?

[onaid]

hi guys just got a gtx 570 and getting a second with corsair hx750w. now my question is will my e8600 @4.2 bottle neck ? and if so i was thinking of grabbing a qx9650 and overclocking it...

ps dont want to go i7, not yet

cheers :)

evga 750i ftw
e8600 @ 4.2
gtx 570 (soon sli)
8gig dominator 1066
kingston 64gig ssd soon to be 250gig
corsair hx650
corsair h50 cooler
all smashed into silverstone lc13
extra 120mm coolermaster right above 570.

Do you have win vista or 7? Check the experience index if you do. I'm not sure what kind of performance you're getting at 4.2. I'd assume it's still pretty good.

win 7 64bit rating for cpu is 7.2

[x88x]

Yeah, at that point I think the e8600 will be your bottleneck. Whether a qx9650 will change that, I'm not sure. For programs that take advantage of more than two cores, yes. For programs that don't, no. Also, as a point of interest, I think with a qx9650 your bottleneck will then be the speed of your RAM.

The c2d would very likley bottle the 2x570. But a quad core would help depending on the program... ex. Bfbc2 your gpu's would very likley barely sweat while your CPU is going nuts.
Also... I went i7 for $300 ish

Quad would almost definitely help - my stock Q6700 at 2.67 gets a 7.2

well i guess i can only try the qx9650 dont think i can push the e8600 any more. realy didnt want to go i7. there is ways the qx9770. if i go i7 that means mobo ram cpu, basicly the lot....:( dont know what to do.

Ya I agree with the post about how not all programs can take full advantage of four cores yet. I noticed that on your Mobo the max RAM is DDR2 at 1066, that could be slightly bottlenecking you. So if you do go to 4 cores, a RAM upgrade is in order, which means a new motherboard. Hope this helps.

At that point he might as well upgrade to Sandy Bridge or AM3 with DDR3. Besides, 1066 is about as high as DDR2 goes.

I'm saying if he keeps the setup then drops in a Quad Core his new bottleneck would be the RAM in my opinion. I know 1066 is the highest for DDR2, that's why I said to get a new Mobo for DDR3.

Agreed. But s775 doesn't do DDR3, so to upgrade the RAM speed, he would have to upgrade not only the MBB but also the CPU, and he already said he didn't want to do that.

s775 does do DDR3, it's just finding a DDR3 motherboard. At which point there's no point in not just going AM3 or SB.

Right, sorry, I mixed myself around there..the i-series was when they integrated the memory controller, not the Core 2 series.

[onaid]

thanks guys will have to sit down and think about this one. looking at some evga classifieds at the moment

I do recall seeing some benchmarks, though, that showed little to no difference between DDR2 and DDR3 with socket 775.

It was probably an old review. When ddr2 came out ddr was still superior for quite some time. The same thing happened with ddr3 vs ddr2. The newest ddr3 is now higher performance. It just took a while to get lower timings on the higher frequency memory. ddr4 should be out shortly, but don't flock to it right away! History repeats itself.:)

And here I am, stuck with DDR1 mem.

Does it not do everything you want? ;)

[AmEv]

Not quite as much as I want.

Is there a 478 board with DDRIII???????

[x88x]

I highly doubt it...besides, even if there were, your FSB would be severely limiting it.

[AmEv]

800MHz.


Definitely DDRII. I know where to get one, too, at the 'Egg.

[Blibbax]

Woah, woah...

Firstly, whether that CPU is holding you back depends massivley on the game, resolution and desires level of AA.

Secondly, is there anything you want to go that you can't do? If yes, don't upgrade.

Thirdly, WIE is an AWFUL CPU benchmark. Take some FPS readings then compare them to what you see in GTX570 reviews (making sure that you use the same part of the game and identical settings).

Fourthly, it's never a great idea to pump money into obsolete tech. You pay above the odds and will replace it fairly soon.

Fifthly and finally, RAM is definitely not a considerable bottlekneck here, even with a quad. Remember Skulltrail? Ran on high latency 800MHZ RAM, destroyed everything at the time. Contrary to popular belief, current RAM speeds are plenty for modern hardware. This can be seen in the total lack of performance difference between X58 and P55, and in the fact that most "extreme benchmarkers" don't bother to overclock their RAM beyond what a lot of people use on a daily basis. Even on the latest platforms, the performance differences between the RAM speeds in OP's system and the best out there when it comes to real world applications are fairly slim.

wow cheers guys, i rekon i will give it a crack anyways and see how it goes, thank you for all your help will let you know.
