GTX560 + Q6600 = Bottleneck?

Hi,

I would like to ask if my Q6600@2,9Ghz would be a big bottleneck with gtx560 (or 6870) ?

If any, it's going to be minor. Try and get that cpu to 3.6ghz.

@Yesitsmario, that's a 1ghz OC from a 6600, without liquid cooling I don't think that'd be a good idea.

@OP, a Q6600 would be a bottleneck, but not a huge one. What games/settings/resolution are you going to be playing at?

I would but I can't get it stable for more than hour at more than 3Ghz. It's probably either my CPU failing or PSU (450W) won't make it.

And yeah, I know that PSU might not handle gtx560 but I'll try anyway. It's handling gtx260 core-216 now which doesn't have that much lower power consumtpion.

@borisof007 - basicly all the new ones at 1680x1050.

A Q6600 @ 3.6ghz actually be a 1.2ghz OC. :whistle:

@mousemonkey - it is possible, as many people has proved, though I'd need a better ram and PSU. Maybe even motherboard. But that's offtopic :)

I never said it wasn't and as I've owned and OC'd a Q6600 I think I've got a reasonable idea of what one can go to on air cooling.

Oh, sorry. I thought I saw a doubt there :ange: 

But to get back to the topic - so It' won't be that much of a bottleneck?

TBH I'm not sure but I intend to get a pair of 560's to run in SLi with an e8400 @ 3ghz.

A pair of 560's with ANY cpu at 3gz would be bottlenecked. Oh and you would get a lot more fps per dollar with 460's sli'd.

Anyways, at that resolution a Q6600 at 3ghz would be a bottleneck, but if you were playing at 1920 and above it wouldn't be so much.

I'll let you know when I get them.

I used to run a Q6600 @ 3.2Ghz (had an 680i motherboard that sucked for OC'ing). I ran it with an 8800GTS 512MB, then a GTX 260 Core 216, and later dabbled with GTX 260 SLI. Eventually I upgraded to an i5-750 and OC'd to 4Ghz. Though my Q6600 gamed very well, I definitely noticed performance improvements from the Q6600 to the i5. Granted the i5 OC'd better, but the architecture is better anyhow.

You should do fine with a GTX 560 Ti on that Q6600. However, since there are a couple of game titles these days that like fast quad cores, you could lack a little in those cases. Just run as high a monitor resolution as you can and you'll minimize any potential for seeing a bottleneck visually speaking.

The GTX 560 Ti appears to match the GTX 470 performance wise in early reviews. And in my experience, a GTX 260 SLI pair equals a GTX 470 as well. Based on my own personal benchmark results in July 2010.

I would buy an i5 (sandy bridge of course) but that would mean changing my mobo + ram + psu and for that I do not have money now. I think i'll just buy the gtx560 and see for myself.

Btw - 450W should do for gtx560 right?

So long as it's a good one and I know what you mean about the SB rig.
January 25, 2011 9:14:36 PM

Im not a overclocking expert, but with a freezer 7 pro, I had mine running at 3.2ghz, and for awhile 3.4ghz, its still a powerful cpu, just old.

It's an old chieftec but so far it has proven itself a good one. Glad I'm not alone.

I have Scythe Mugen 2 and the temps are really low, but somehow I cant' OC it more than stable 3,0Ghz. Dunno what it is.

What motherboard and RAM is it on and what voltages have you tried?

Mix and match ram makes for OC difficulties.

Sup man? I also have a q6600 and is interested in the EVGA GTX 560Ti. I see from your sig that you already got that GPU. How is it working out for you? What have you ran on it so far?

Looking forward to your reply

Respect

It's working flawlessly for me. I've tested it with Heaven Benchmark with everything maxed out and got 26fps. As for a games, i've tested it with AVP, Crysis Warhead, Dragon Age II and basicly most of the newer titles and I do get a stuttering now and then but it's really rare. So I say go for gtx560ti, you won't regret it :) 
March 4, 2011 7:24:04 AM

Thanks man. I basically have the same setup as you. 2 x 1GB 800MHz RAM, Q6600, 680i MoBo, so I definitely should be experiencing a similar performance.
Is your CPU still OC'd at 2.9GHz? I've read that we need at least a 3.2GHz to not bottleneck a GPU like this.

~Des
March 5, 2011 8:16:52 PM

Yep - I'm stuck stuck at 2,9Ghz. I'm still trying to get 3,2 stable. I don't feel that cpu at this speed is a bottleneck though.
April 5, 2011 8:33:01 PM

I've read that the nForce 680i Chipsets have a prob OCing C2Qs past a FSB of 1333, unless it is the A1 Revision. I know EVGA revised their 680i MoBos after Nvidia made the update available back in the day, but the one I have from ASUS sadly did not appear to have any such updates.
I dunno about your Abit IP35-E MoBo, but it is something you could check out, or, based on your the other thread, it might just be your PSU holding you back.

Im using a q6600 at 3.006 MHz, with GTX560 ti oced, and its been a significant improvement over 2 4850 with aftermarket cooling in crossfire and overclocked.
Basicly in last level on crysis warhead i went from totally unplayble and 40% crash chance to smooth game (physx by GPU).
It does bottleneck, but its actually due to the cache memory ( as far as i know) rather than the CPU transistors or build.
On a side note, i cant oc higher than that due to a motherboard bug, and i game at 1900x1200, max settings, as long as the frame rate is decent.

Hey bud

I have the Asus P5KC Mobo, with Intel q6600 GO oc to 3.21 GHz, running idle at 30 and load at 55, air cooling. The cpu has only shown a bottleneck when benchmarking the Resident Evil 5, stuck at 60fps, but once I purchased a 1080p monitor, no bottlenecking at all. Not so promising results though, as Heaven Benchmark at all max no 3d ran at about 15 Fps average, but going to buy the Asus P5n-T deluxe soon, to try SLI this cpu, its just too good to upgrade, yet.
