1156 vs 1366 i7 CPU's

[Mike Harvey]

So a quick question... with CS5, am I going to see that big of a difference with a 1366 i7 vs a 1156 i7? I know you get triple channel memory with the 1366 vs dual channel with the 1156, but is it that big of a difference? I ask because going the 1156 route would be cheaper for me as the boards seem to be cheaper and I can recycle my existing memory... thus allowing me to plunk down on a supported CUDA card (or soon to be supported GTX480). But if the performance is that different, I'll forgo the CUDA card and spring for the 1366.

Thoughts?

the cpu itself does not change performance, but the motherboard you will be able to select will change a lot what you will be able to do.
more memory slot, more PCIe slot, more features, better chipset are more important than the choice of the CPU.
i would definitely go with 1366, especially for video, when you potentially could add several card (capture, disk controller, soundcard, usb3, wireless)

Well, I realized after I posted this that I have DDR2, not DDR3 memory, so any board that has any reasonably up to date features I wouldn't be able to recycle my current memory for, so I might as well spring the little extra for a 1366 board.

With an 1366 cpu and board, you have more power pins on the cpu socket and the cpu itself, this increases stability, especially when overclocking or doing something cpu intensive.

Socket 1156 cpus and motherboards are limited to 16 PCI Express lanes which means one graphics card and thats it, if you want you, there would have to be an additional chip on the motherboard which would only be on the higher end 1156 boards and you may aswell get the 1366.

You probably wouldn't notice the difference in dual and triple channel while editing but it may impact on how long rendering will take, but it would be by a few minutes at most.

With the 1366 socket, you could upgrade to a hex core (6 cores, 12 threads) at a later date. With 1156, you are limited to an i7 with 4 cores.

1156 is meant for mainstream computing starting from i3 processors, to 15 then the top dogs at 17, 1366 starts with the i7 and is expected to get an i9 next year, we already have an hex core on the 1366 socket. you wont get this on the 1156 socket.

1136 is a premium, 1156 is for the rest of the world. Ultimatly, the 1136 socket is better but at a cost with little difference in performance but you are limited with upgradability.

The processors themselves right inside are identical, and should perform identically, (assuming the ram is not a limiting factor)

Hope i've helped.
