Interesting page.

Differences are bigger than I (layman) expected.

8 QX6700@3.0GHz Crafty 22.8 x64 t4 2840 500 11796 Sedat Canbaz
9 AMD 4600 2.4GHz Crafty 22.8 x64 t2 2738 500 4020 Sedat Canbaz

.. for example. 100 points is a massive gain at that level...

Indeed,QX6700 is a very good choice if you're planning to buy hardware even nowadays....a good overclocking potential and a good price
I wonder how many MHz can you push it to with a good cooling system

Instead of QX6700,i recommend:
i7 920,at least with a good cooling it can be easly overclocked approx. @4.0GHz,thats means approx.50-70% faster than QX6700

And the price between both hardwares are almost same
(a little bit is more expensive i7 920,but the speed difference of Core i7 920 is too much... )
In other words nowdays its possible to build a very fast hadware for approx. 1500 usd

About overclocking QX6700,some people can very easly reach around @3.2-@3.5GHz with a good air cooling,and some people(including me ) can overclock it only 10%.Of cource i can overclock it @3.3GHz but when i run the Prime95,it starting the errors...
I think the reason is my motherboard or maybe the reason is my QX6700,becouse this processor is very old version,its the first releases- since 2006 year.

Thanks for your interest...

Not only with Crafty...the rest of the engines have the same elo (100-120 elo)difference,between AMD 4600 and QX7600

Thanks Sedat for this valuable information,I'll go for i7 920 then

I will be getting an i920 to see what the fuss is all about. It seems to be performing very well when you look at the kns speed that Rybka 3 shows ... even better or very close to 8 core 3.2 Ghz. But on Playchess with games against 3.8 ghz i7's I feel that the 8 core 3.2 Ghz is stronger and the 4 ghz 8 core much stronger. But really to get that little extra strength you are spending a fortune which practically is not worth it.

I will say though that you can get an 8 core 3.2 Ghz today for around $1600 for motherboard + 2cpu's + 4GB 800 Mhz FBDIMMS. Ofcourse if you don't have a very powerful power supply you would need that too, but otherwise your old stuff can stay the same. A good Core i7 system would probably be around a $700 upgrade and with a good cooler around $750.

Thanks Majd,I'll have this in mind when going for a price hunt in the market,I thought that an octal machine is much expensive,but reading your post made me second guess my decision

Majd,

Let's test your 2x QX9775 @4.00GHz against mines,you know we need games then we can make better conclusion and also i can create a rating list to compare the elo difference

Btw,if you have free cpu time for example tomorrow we can test our hardwares on playchess server

Hi Sedat ... have been on Playchess few days now but can't seem to catch you. I will try later tonight as well. Maybe we can get Phil to test against Skulltrail at 3.2 Ghz and 4 Ghz. As for Core i7 prices ... they seem still pretty high with motherboard and DDR3 memory being much higher than normal DDR 2 and LGA 775 motherboards. It does seem that a properly configured i7 can run at 3.8 Ghz, and it would be interesting to see if at that speed it can beat a 3.2 Ghz Octa.
