Get the 4000, its worth it. You will be set for a while... wont need to upgrade like everyone else that has a 3500 or lower. Especially if you have/are going to have a Sli setup... Sli setups require more CPU power. If you short change yourself with a lowend cpu then you are only shooting your GPU potential in the foot.
Oh, and the site looks nice. Reminds me of Essential Computers before they dissapeared.
I just went from a 2400+ to a 4000+ and let me tell you... WOHOO!!! Its insane. I was gonna wait for the E3 revision San Diego Core... but They wernt gonna make it to market for another month or so, and the preliminary prices seemed to be way more expensive. After wanting to build this rig for a year... I just couldnt wait one more month Although in hind sight... I probably should have. Oh well.
i dont have a cat... but god help them if they touch riely (my new black lab) and i have decided to wait for a dual core. Revision E as you call it.. if i wait long enough then.. i can have better and better...
Upgrade time is coming in May (end of it) i will be building a completely new rig. and you will all input.. hehe
