This is my build. The aim is solely gaming. I'm now confused as to the best processor for gaming. I thought it would be the QuadCore, but it appears I am wrong. If so, what processor would you all recommend?
For nearly $100 less and you could do the OC yourself (In case you don't know, 8800 Ultra is just a fancy name for slightly OC'd 8800GTX)
And before someone tries to be smart and say that the Ultra has OC'd shaders, well... you can OC the GTX shaders too, just needs a different approach (a slightly risky one) with NiBiTor. But OCing Memory and Core is a piece of cake (shaders don't affect all that much performance, at least not yet anyway).
Basically what I'm trying to say is, Get a normal GTX and OC yourself (probably beyond Ultra speeds if you want).
EDIT: that ram is overkill, just get these, you can OC just fine with them.
Stop trying to get one of the extreme edition chips. They are completely pointless. There's not extra cache in them or anything, they are simply clocked higher and the multiplier in them is not locked. You're only throwing money away by buying one of them, unless your intention is to use the multiplier to overclock the chip (or both the multiplier and the FSB frequency). These are the only 2 chips you should bother considering for this new system:
if he's really in the need for X6800 speeds without OC'ing and he doesn't care about burning money (One would think so seeing him only going for extreme edition overpriced stuff), I think in this case the E6850 would be an option worth considering.
X6800 - 2.93Ghz, 4MB Cache, 1066FSB, Unlocked multi - $950-$1000
E6850 - 2.93Ghz, 4MB Cache, 1333FSB, Locked Multi - $270
Both chips will most likely perform the same, and the E6850 will be released on July 22 as I tried telling you on my previous message.
You see all core 2 duo chips work with the motherboard's quad pumped FSB (set at 266*4 = 1066 or 333*4 = 1333 depending on the chip). This FSB is multiplied with the processor's own multiplier to get the clock speed (E6600: 266 (FSB) * 9 (Multiplier) = 2400Mhz). Most chips have a locked multiplier so you can't change it, and the only way to overclock is to either raise FSB or raise voltage, However intel's "Extreme Edition" chips come with an unlocked multiplier to give the user more overclocking options at the cost of insane prices of course.
It's really not worth it unless you are crapping so much money that you don't know what to do with it.
