Which would you choose if the price was the same (within 15 bucks)...

Intel Core 2 Duo E8400 Wolfdale 3.0GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor (45nm)
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115037

Intel Core 2 Quad Q6600 Kentsfield 2.4GHz 2 x 4MB L2 Cache LGA 775 Quad-Core Processor (65nm)
http://www.newegg.com/Product/Product.aspx?Item=N82E16819115017

either using this mobo:
ASUS MAXIMUS EXTREME LGA 775 Intel X38 ATX Intel Motherboard
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131235
http://usa.asus.com/products.aspx?l1=3&l2=11&l3=572&l4=0&model=1862&modelmenu=1

(w/ 2 gigs OCZ ddr3 pc3 10600 1333mhz sdram)

The problem is the c2d e8400 45nm (original choice) is out of stock (3-5 weeks) everywhere, except for like one online place who is gouging the price, and I cannot wait that long for the new pc, hence I started looking at 65nm C2D Quads (Extreme Quads are out of the question, $1000+ just for the cpu, pffft!)

thanks for any input

I'd get the Q6600, i've got a QX6700 and it's an absolute tank, but i've used a PC with a Q6600 and almost the same RAM specs as well (the one I used @ work had 1GB 800MHz) and it's a great entry-level quad, and certainly a top-line CPU by any means.

Well worth the moolah imo.

Unfortunately, I'm in the same position as you.

By next week I will have all the parts for my new computer except for the CPU. The Quad core is nice and readily available, but a lot of its power will not be utilised since not many applications/games are optimised for using more than 2 cores. On the other hand the E8400 is clocked at 3 Ghz per core, compared to the 2.4Ghz of the quad, can be easily overclocked and at the same time runs cooler and requires less power. The only problem is that it cannot be found anywhere . At one point I also contemplated the option of choosing a lower specked and cheaper one such as the E8200 or even the E6750, but then desisted.


In the end I think I'll wait for the E8400.It's really a shame, especially when considering that my 8800GT is crying to be used.

P.s. It's unbelievable what happens to prices when there is scarcity. One store I consulted was ready to delivery it by next week at the reasonable price of 360Euros ($550)

Theory is when you know something, but it doesn't work. Practice is when something works, but you don't know why.
Programmers combine theory and practice: Nothing works and they don't know why.

yep

I think I may just get the the q6600 quad, since that mobo is an OC monster if I ever want to oc it.

what would be your choice if all factors were removed (price/availability) and you could have in hand either one upon deciding?

edit: I guess you already answered that (e8400), nvm
unfortunately I cant wait, this is holding up some development work I need to do. gaming wasnt an issue

forgive the "elderly" moment, but I have a dumb question...

If I get the quad processor at 1066 fsb (stock setting), does that mean I cant use ddr3 1333 memory, or can I? And if so, if the mem is 1333, will that automatically push the 2.4ghz cpu into the OC range of 3.0ghz? I dont necessarily want to do that...

I'm choosing the 8400.

I want to use it as 24x7x365 game server and it will save a huge ammount of power using 45nm and super speed stepped. The q6600 will leave 3 cores running nothing wasting 6x266 power if your just running a single threaded DBP program.

The 8400 has a wider 333Mhz buzz meaning faster access to memory and GPU per clock and a wider cache. The q6600 is well known for it's cache bottleneck.

Dark Basic isn't multi-threaded so DB stuff will run faster on the 8400 pure and simple.

The 8400 seems to be overclockable to 4Ghz from early reports.

Finally if you really do need a quad spend the extra £40 on a q9300 it will pay for the extra £40 in one year on the ammount saved on your electricity bill!

p.s. at the moment stocks of the new chips are being diverted to ISPs and bulk producers. For a cracking deal try somewhere like Dell. http://www1.euro.dell.com/content/products/productdetails.aspx/inspndt_530s?c=uk&l=en&s=dhs&cs=ukdhs1 3rd one from the left and choose the £20 upgrade to the 8400 £50-100 cheaper than I can build one from same spec parts. Just sell the ram and gpu on ebay if you want cash back for faster stuff.

I ended up ordering the Q6600 since I couldnt wait for the e8400's o become available. I am sure it will be a vast improvement over my P4 3.2ghz lga 775 cpu

the mobo I am getting supports current 65nm, and next gen 45nm chips, as well as ddr2 and ddr3 memory (I have 2 gigs of ddr3 1333 coming) so in a year from now, or whenever, I can always have the option of simply swapping out the cpu without another major rebuild. Ill post a rig specs thread in a bit

oh, and as for electricity, the new cpu uses 65w, my current one uses 83w

thanks for the help and suggestions

The watt rating is really a max rating 45nm use way less than 65watts.



As the q6600 idles at 29watts it's a nice improvement from Intel that e8xxx range can be running at full pelt for this many watts. AMD have basically lost the plot on energy efficency
