Hi,

Is it a good mix ? put a ATI Radeon 5870 with my q6600 ? or the cpu will not follow my 5870?

I used to have a q6600 b3 stepping. It was impossible to hit anything over 3ghz on that thing and the temps then got pretty hot at 3.0ghz. If yours is a G0 stepping try seeing if you cna atleast hit 3ghz and ull be good to go.

A Q6600 stock wont bottleneck a 5870. A OC to 3GHz wouldn't hurt keep the flow there but not 100% necessary.

Now if you ever plan to do a CF with another 5870 then you will want to OC it more or possibly upgrade the CPU to a Q9550+.

I have seen many people and benchmarks saying a stock Q6600 will bottleneck a 5870 easily - very much so.
need to push it to 3.3GHz+ to get most of what you should have outa the 5870

and have seen some benchmarks showing a Phenom II X4 4ish will also limit the potential (in certain benchmarks).

to truly get the Most (is over the top 75 - 135fps) you'd need a i7 @ 4GHz + which could give over 30 more fps compared to the Phenom in a few specific tests.

Spent some time looking at this a while back - the benchmarks showing this persuaded me away from my AMD leaning to maybe go I7 soon - even if not necessary.

Even at 3.6GHz a Q6600 (what I have) will not allow the 5870 to give its full potential - Think I am going to stick with it TBH though as will give close to 60ish FPS at all res I need :)

Nice talk without knowing all the facts. Like the resolution. If the OP has a monitor with 1920x1200 or higher resolution all this talk about CPU bottlenecking and CPU overclocking is pretty much useless, because at those resolutions with all details to high/very high the GPU will become the botttlenecking part and not the CPU. My advice to the OP(seeing he has 3 monitors) is to go with the 5870 and an Eyefinity setup and forget overclocking the CPU.

not qiute so actually as I was considering 1920x1200 as it is what I will be gaming at...

as I mentioned - it was only in some specific benchmarks, not all by a long way.

Your own coments apply to yourself too ;)

My comment is based on the hypothetical chance that he has a monitor with a bigger resolution. The fact that he has 3 monitors and wants to buy an ATI card makes me think about the Eyefinity setup possibility. When using Eyefinity he will experience GPU bottlenecks at high/very high details and in my opinion a CPU overclock to 3.2+ GHz will not account for anything more than 5-10% FPS increase. That in my opinion doesn't worth shortening the life span of the CPU.

hypothetically I agree with you, we are both as right as we are wrong with what info we have on the res part :)

but a Q6600 going from 2.4GHz to 3.2GHz+ is not that small an OC and can account for a Lot more than 5 - 10% fps increase when it is bottlenecking a great GPU

Hopefully he can make a more stable OC with a little help from here ;)

The same advice was given to me when buying the 4870 for the 1680x1050 resolution. And you know what...I OCed the CPU to 3.2GHz. The result: an increase of 2-3 FPS in the games I played at that time(mostly shooters - including Crysis). So I returned to stock and enjoyed my games without the extra FPS.

well, I guess I shall dig out some benchies later after I finish my work and we can see what is what. Am curious to refresh my memory on this subject as am very soon looking to buy a 5850 and OC it or maybe a 5870 for AvP :D

I run my Q6600 at a very light 3GHz OC atm as no need for more till then and am lucky that mine is totally stable also at 3.6GHz - though gets a little warm running folding@home for my liking at 75celcius (167f)

Lets see

I try AGAIN to OC my Q6600 ...without any good result ... Y try N.O.S. feature of my P5k .. @ 30% ..hehe didn't logon...

@10% ...it work but the next day when I reboot my damn fan run full trust ...I have to reset my pc ... after ...fck all ...clock is jam @2400 and no setting in my bios is effective ... I have to reset cmos to OC again ... it's pain in the a** ...

I don't what is wrong with my pc :( ... I guess I "need" an another one :)

LOL. Come on. Buying a new CPU for a maximum 10 FPS increase in games. Some people have way too much money to burn.

What type of heatsink are you using with this CPU? What kind of temperatures are you hitting on the CPU at stock and OC settings? When you say 10%, are you using the automatic overclocking features in the BIOS? You may want to try to manually OC'ing instead by increasing the CPU Multiplier, Bus frequencies, and/or voltages, if necessary (be careful adjusting the voltage too high, as you may damage your CPU).

Yeah I expect more than 10 FPS. More like 15-20. But, changing the CPU to I7 requires a full platform change: new motherboard, new memory. So basically you are paying hundreds of dollars for 15-20 FPS. GG

Pfff temp ... I don't know ... but each time I watch it's seem normal ...

Yeah 10% is the N.O.S. Asus P5k feature ...

Manually I put my cpu @~3.4 ... but jusr before Logon I got blue screen :(
Exact same that http://www.bit-tech.net/hardware/c [...] ad_q6600/1
But my setup is not a p5k Deluxe ... and not same ram ...

An another thing I have ... some time (first boot of day) ... my pc wont' start ... Fan in Full spin ...I have to reset 1-x times to finally start! (any Idea?) maibe this problem is link to my OC problem ?
