Intel quad core vs amd 8 core is it worth it?

Hello,
I am looking for any kind of comparison between a intel quad core Q6600 overclocked to 2.88 and a new amd 8 core overclocked to 4ghz. Would there be enough of a difference to justify a new purchase? I just do movie conversion and bluray burning mostly. Thanks

your cpu should be about as powerful as the phenom x4 840
OC on the 8150 will scale with clock rate so the 4gh OC will see 10% increase in performance.

You could check Anandtechs CPU benchmark.

While none of these are overclocked, it will give you an idea of what to expect.

If the files you are converting are already on your HDD then your bottleneck should be the CPU. From benches I've seen the FX-8150 is quicker than the 2600K (both at stock speeds) by a fair margin. That being said, how time critical is video conversion?

friend, do not ans blindly fx 8150 isn't quicker than 2600k however 2500k is better then fx 8150 they aren't too powerful cpu's.

If you want to upgrade for that kind of budget = FX 8150 price class
Another similar cost option is the i7-2600k IF you live near a microcenter (since through newegg it should cost 50 bucks more than FX-8150)
AMD FX-8150 vs Intel Core i5 2600K

If you a want cheaper, but overall better CPU, you should check the i5-2500k.
As per this link: AMD FX-8150 vs Intel Core i5 2500K
If you check carefully the i5-2500k is faster in almost all aspects than the FX-8150, except x264 HD Encond Test - 2nd pass (i5-2500k is faster in the 1st pass), and some of the rendering options

All this without mentioning the huge difference in power consumption, if you OC both CPUs the difference go way deeper yet (the Intel ones are more power friendly)

Power consumption:
The Bulldozer Review: AMD FX-8150 Tested - Power Consumption
AMD FX-8150 Power Consumption
Power Consumption: FX 8150 v i5 2500k v i7 2600k

As example: If you OC both CPUs (2600k and FX-8150) to 5ghz levels, to speed up video encoding, let's say it's your primary usage, and you does this about 4 hours a day.
Let's assume an average power consumption based in these OC test, power difference = 224W, 4 hours/day, 30 days/month equals almost 27kWh
Here in Brazil a 1kWh costs about USD0,30 -> roughly power bill will be USD 8 a month expensive if you stick with FX-8150 OC, than i7-2600k (without mentioning the i7-2600k realistic would spend less time doing it, since it's faster)
In 6 months you would save enough to pay the i7-2600k difference
