Intel Core i7 Quads!!!!!!!!!!!

[Nairi]

The current crop of Core i7 are 4 physical cores with hyperthreading to make it look like 8 logical cores.

And previous posters are correct in that multiboxing is not cpu limited. Your current quad-core LGA775 Core 2's are more than adequate for the job. If you're experiencing slow downs, it's your graphics card and i/o.

Heh, you really don't know where I work do you?

You want to spend serious bucks on the newest gear... I understand that. I've gone down that road before.

But, you'll soon find a point of diminishing returns and the Core i7 won't be the silver bullet that you are looking for. I know, I'm staring at a few Core i7 cpus/mobos at work and a shiny new Falcon Northwest machine. Great for video rendering, but guess what folks still laggy in Shatt because of ... you got it ... a hard drive.

Good chip, yup. But multiboxing WoW isn't CPU limited, especially with regular quad-core. You may get a few frames per second increase. If this justifies spending the thousands of bucks on a new machine, then more power to you.

Hard drive i/o or the whole cpu/mobo i/o?

i7 increases i/o proformance with built in memory controller, this allows for more head room for GPUS and devices...
Lets not forget the tripple channel DDR3.

instead of going back and forth with this 'its not the cpu its the gpu' lets see some benchmarks people.

btw hard drive i/o can easily be avoided get some ultra fast ssd with crazy i/o or multiple harddrives per sessions.
