also OC'ing Mobo's is possible, you just crank the FSB up, only 10% max with single cored chips up to 30% with dual cored, plus the multipliers are unlocked on dual-cored up to 20X. So i did the math,
Single Cored Core/FSB speeds:
Stock: 15X= 3.0Ghz/800Mhz, 16X= 3.2Ghz/800Mhz, 17X= 3.4Ghz/800Mhz, 18X= 3.6Ghz/800Mhz, 19X= 3.8Ghz/800Mhz, 20X= 4Ghz/800Mhz
OC'ed: 15X= 3.3Ghz/880Mhz, 16X= 3.52Ghz/880Mhz, 17X= 3.74Ghz/880Mhz, 18X= 3.96Ghz/880Mhz, 19X= 4.18Ghz/880Mhz 20X= 4.4Ghz/880Mhz
Dual Cored Core/FSB speeds:
Stock: same as above
OC'ed: 15X= 3.9Ghz/1040Mhz, 16X= 4.16Ghz/1040Mhz, 17X= 4.42/1040Mhz, 18X= 4.68Ghz/1040Mhz, 19X= 4.94Ghz/ 1040Mhz, 20X= 5.2Ghz/1040Mhz
But by my calculations using an Artic Freezer 7 Pro CPU cooler due to heat limits the fastest possible on dual cored (this is an estimate) would be a 16X, 17X, or 18X multiplier on the core at a 30% OC, otherwise the CPU cooler couldn't handle it, due to it only being able to dissipate 200watts of heat, but using a stock cooler these numbers would be near impossible to reach. But as you can see usign a dual-cored CPU on the dual-cored motherboards would actually be faster, using a P4 840EE or the soon to be P4940EE you could probably (definanately with a 940EE) out run an Intel P4EE 3.74Ghz or any other one, but if they happen to go with a 65nm process of the 940EE heat limitations may not be a factor and possibly even be able to OC that baby to 5.2Ghz or 4.94Ghz. But high CPU core frequencies are not necessary if you only play games, that would only really require stock CPU speeds and faster bus and memory speeds, keep in mind OC'ing base FSB bus speeds will increase all other speeds as well, so PCI, PCI-E, Memory, and maybe even other speeds and bandwidth may be increased. I've estimated a MAX OC of PCI bandwidth from stock 133MB/s to 172.9MB/s or even 228.918MB/s, PCI-EX1 from stock 2.5GB/s uni-directional 5GB/s bi-directional up to 3.5503GB/s uni-directional, 7.1006GB/s bi-directional, PCI-EX4: multiply X4's by 4, X8's multiply X4's by 2, X16 multiply X8's by 2
but to save you time PCI-EX8= Stock 20GB/s uni, 40GB/s bi, OC 28.4024GB/s uni, 56.8048GB/s bi
PCI-EX16= Stock 40GB/s uni, 80GB/s bi, OC 56.8048GB/s uni, 113.6096GB/s bi,
note these are dual-cored OC'ed mobo's, single cored chips only have a max of 10% oc unlike dual-cored's 30%
bi-directional items are things such as internet cards i believe, however graphics cards i believe are uni-directional, Why does bandwidth matter? because things like high-end graphics cards need lots of it. my X1800XT for example has 48GB/s of bandwidth so to use it's full potential i increased bandwidth, since i only have one GPU in my system. however if you have two GPU's such as a crossfire system, i highly recommend a dual-cored chip, wait until the 9xx series is released along with the 975XE mobo. because i highly recommend a dual-cored chip so for instance if both of my X1800 cards in crossfire making both X8, instead of having only 20Gb/s of stock bandwidth each can have 28.4024GB/s of bandwidth in each. hopefully intel will release a new mobo after that with dual PCI-EX16 slots. so each card has it's full potential used.
