Nowdays pc games are stubborn(without good hardware u can't play well), i agree with riider but game u mentioned require quad core to run smooth.

U need to disable intel speedstep to unlock multiplier, u can't increase multiplier because Q8400 isn't extreme edition.

You can, unless the OEM CPU is installed in a proprietary case (a small form factor Dell, for example).

Socket 939 | Dual-core Opteron 185 @ 3.2GHz | 4GB | 1.0TB | Win7 x64
GeForce GTX 460 1GB | X-Fi Ti Pro | A8N32-SLI Deluxe | Antec P182

awesome! its a home build so its a full-atx mid-tower, etc... not proprietary at all... ive been getting by with an e7300 dual core for too long now, and i came across a good deal on a q8400 - but oem, so i wanted to make sure they used the same setup... thanks for the help/reply..!

"ive been getting by with an e7300 dual core for too long now, and i came across a good deal on a q8400"

You'll be wasting your money. If you have a decent board, it would make more sense to just reclock/overclock the e7300. I understand the dual vs quad argument, but unless you're running programs that will actually take advantage of the quad, that argument is out the window. Other than the difference in L2 cache (3MB vs 4MB), the only difference is FSB speed. And to make up for that, all you'd have to do is reclock the e7300 from 10 x 266MHz/1066MHz FSB (2.66GHz) to 8 x 333Mhz/1333MHz FSB (2.66GHz). Or you could even take it higher than that - 3.0GHz (9 x 333mhz) for example. Or if your board supports 1600MHz FSB & you have the right RAM, you'd have a whole slew of other possibilities. BTW, how much RAM do you have & what speed RAM is it? If you only have say, 2GB RAM, that's where you should be spending your upgrade money, not wasting it on a CPU.

i love this site just for this reason: people know what theyre talking about!

so here my breakdown of system specs and logic:
e7300 c2d @2.66
6gb DDR2-800 [cas5 mushkin enhanced silverline]
gtx260 core 216 896mb
msi p43neo3-f
windows 7 home premium 64 bit
so basically this is what im thinking:
1] socket 775 processors are quickly becoming harder to find
2] RAM not really limiting me at this point
3] msi board has a locked multiplier, so i can only adjust voltages and fsb - not to mention the fact that i am a complete novice at OC
4] if BF3 is any indication, multiple-core processors are going to become more and more of an issue for those of us locked in the dual core [or worse] world

basically its like this, between BF3 and some other, non-gaming software that i run it seems that my CPU is topping out while my GPU is still only at ~70%... im certainly not thinking that this upgrade will be and end all solution, its just a place to start - my PC is CPU limited right now, and without the funds to do a full MB/CPU/RAM/GPU upgrade at this time, i was hoping to bide my time by getting the quad-core now [assuming with a side of hope that the extra cores will pay off in the long term] and follow that up with a GPU upgrade to a 560ti or better with tax return in february... hopefully that will buy me enough time until i can afford a more comprehensive upgrade...
so thats my thinking. i would certainly like to hear feedback regarding it - i have built PCs for years, but i know i dont know everything by a long shot, so if there is a flaw in my thinking that im ignorant of, please feel free to let me know! thanks again for all the help...

so, a quick follow up:
got my q8400 today, and it almost doubled my FPS in BF3 from avg ~25-30 to ~55!!!
totally awesome!
the catch: my c2d was a 65w, and this quad-core is a 95w, so the HS & Fan dont hold up... no copper core on this heatsink, and <2000rpm - under load CPU approaches 69 degrees...
that being said, is there anything i can do with voltages or FSB to keep the heat in check until friday when i can get a new fan/HS..? any advice or info would be great... thanks to all who offered help!

69C if under load, especially while gaming is really not that bad. Your CPU will be fine in that range. If you got 69C during web browsing and closer to 90C or higher, then I would be concerned (long term). Know that if you reach the thermal limit of the CPU you would get a forced shut down to protect it so you only need to worry about the long term if you ran it very hot for extended periods of time.
If you keep a temperature monitoring program open and check it periodically during gaming and it remains within control, then you should be fine.

You have to be a little bit crazy to keep you from going insane.

thanks for the info, fingers... im just a touch paranoid - i think mostly from being so used to the 65w core 2 duo, now it just seems so damn hot!!!
anyways, its good to hear that those temps should be okay... it hasnt hit 70 while gaming, and normally between 50-55 when web browsing or whatever, so i guess its okay - just not what im used to!!!
thanks again everyone for your help...

71c is the maximum safe operating temperature for q8400. Only aftermarket cooler comes with copper core. Enjoy BF3.
