Yeah I mean tripple channel, my bad.

Information taken from and to see graphs. http://www.overclock.net/intel-gener...uide-p67a.html

Next while we are working with the AIDA64 EE program, I used this program to also do memory benchmarks, here are the memory bandwidth benchmarks:

Now remember that at 2.8 GHz the 2600K is at 1066 MHz memory. I also included 2600K at 2.8 GHz with overclocked memory to show the difference CPU frequency makes to memory bandwidth. As you can see it does improve memory bandwidth some. We are using the i7930 in dual channel configuration, triple channel should do a bit better, but I wanted to compare the systems on an even plane. As you can tell memory bandwidth is an area that Sandy Bridge performs excellent in without a doubt, just look at how even when down clocked it matches the i7930 at 4.2 GHz and 1600MHz.
Here is the last AIDA64 EE benchmark, it is memory latency:



As you can see again, CPU frequency has a great impact on latency with SandyBridge, the fact that I used/set cas 9 even when SPD was lower was so that I could get nice base line readings.

Now I am wondering a few things:
1. What is a good amount of RAM to have 4GB or 6GB of DRR3 1333 RAM? Would having more RAM for the price make that much of a performance increase vs the Core i5 with the same amount of RAM (either 4 or 6 GB)?
2. Also does anyone know if this is a good mobo or not: Gigabyte GA-P55A-UD3 LGA 1156 P55 ATX Motherboard? I was looking and it seemed like a good choice for it supported both the Core i CPUs I was looking at.
3. If I paired that CPU with an ATI Radeon 5750 with 1 GB of GDDR5 is it going to be able to outperform a system using this Graphics Card with the Core i7 970 Extreme?
4. How would Windrows 7 utilize the 8 threads of the Core i7 2600K processor vs 4 threads of the Core i5 2500K processor?
5. If I do get this processor how many case fans should I use or would need for adequate cooling vs. that of the Core i5?
6. Also should I get a better cooler even though the one I have seen is a boxed CPU? I was wondering that because if I did decide the overclock the CPU would the heat sink included be adequate enough to dissipate the heat generated or should I go with a better solution?
7. I am also going to put a 320 GB HD for OS and applications and 1 TB HD for storage and backup.
Also an optical drive with some form of R/W combination. What wattage power supply should I go with with this kind of set up? Would a 500 watt be enough or should I go with a 600 watt or higher PSU?

Thank you in advance!
There is a great Sandy Bridge RAM performance review done by bit-tech, also has some benches of 4GB DDR3 vs 16GB DDR3 - surprisingly almost no difference in performance.

I started choosing the processor last month and I had pretty much locked it in that I was going to go with the core i7 970. But now the new sandy bridge processors are out and have pretty much put me back to step 1 !!

The purpose of the computer is a mix of hardcore gaming (latest fps and rts), amateur hd video editing (home movies), Watching movies, light image editing (photoshop), office applications (word, excel), general internet, and game/level design (trying to learn UDK).

So my question is what is the better processor the 970 or the top sandy bridge (2600)?
Also 3 things to note when replying:
- I am not interested in value for money. So pretend they were both the same price.
-I have no plans to overclock......(lol maybe this is the wrong forum just a lot of people seemed knowledgeable here). So don’t base them on their overclocking abilities
-I am planning on running sli gtx 580, I am not sure if that changes anything.... (Maybe a certain processor can utilize them better?)

Also just remember when replying that I am really new to this so I am pretty noob and may ask some dumb questions. So try to go easy on me when I do!

go for i7 2600, new ISA, new internal design and new cache tech

Honestly I don't think really matters.

I wouldn't take either if I wasn't overclocking, I'd just get an AMD cpu and consider it weak.

I wouldn't waste $1000+ on gpus either (especially since you aren't OC'ing), but meh whatever this thread is kind out of my element since none of it makes any sense.
