Greetings to all

Im having difficulties deciding witch CPU to get. Im going to use it with Asus P5Q-E mbo and kingmax 800mhz rams.

On the one hand i like the brute performance of the E8400, since it has very good OC potential , but, thinking in the future, quad 8400 may be a good choice also.

Tell you the truth im not using my PC professionally, only what i need is speed in every day jobs (including new and upcoming games ) and stability

Please write your comments on this...

thanx

Q8400 is what i recommend dude.or you can even look out to Amd Phenom II X2 550 where u can unlock other two cores and make it a Quad core.

for the price of theq8400 you could get the ph2 945

Guys i would rather go in intel

If I were you, I would buy Q6700. In UK Q6700 has the same price with Q8400. I know is old and is on 65nm but FSB 1066 make them much better for OC and have bigger cache memory.
If you didn't buy the motherboard yet, I would suggest AMD.

Q6700 is not avaliable in my country.

If its just mostly gaming and general usage then of the 2 you picked - E8400.

With that said, if you really want a quad, then seriously consider the PhenomII 9x0 line. They get performance on par with Intel's top end Q9x50 processor.

A Q8400 will generally net you the same gaming experience as using an E5x00.

well wait a month after i5 has launched ppl will be throwing 775 sockets in the trash you could pick up any q series for half what it is now

i think you are exaggerating a little bit. Common, Q8400 the same with E5x00???

Believe me, I'm not exaggerating. Core2 Quads are really just 2x Core2 Dual, on the same processor package.

Q9x50 = E8x00
Q94xx = E7x00
Q8x00 = E5200, E6300

this is the Q8200 and E8400 comparation

looks to me that the performance is very close

core 2 quads are just 2 core 2 duo's on the same chip
August 14, 2009 3:53:35 PM

i know that but you said that Q8400 has the same performance in games like E5x00

i have that hard to belive

If your game only uses two cores and those two cores have the same spec as an E5200, well you can work out the rest.
August 14, 2009 4:56:53 PM

ok then , how about Q9400?

A Q9550 is the one to go for if you can stretch to it.

$169 for Q9550 if you live near a Microcenter.

I live near Croatia :D 

and believe me, it is very expensive

Ahh, that changes things slightly. CC purchase from a UK site perhaps?
August 14, 2009 5:37:43 PM

no, customs fees are to great , the Q9400 it the top price i can go

I think the E8400 would be your faster option. go Quad when a lot more software actually makes use of them.
August 14, 2009 8:42:22 PM

get a quad if you multitask , or do any of the following :

play far cry 2
play gta4
( note those are the only games that i know that use quads)
work with 3d programs (rendering) programs
video production programs
animation programs
image editing program
virtual machines

that's all i can think of right now .
August 14, 2009 9:05:24 PM

I would like to see some evidence that gta4 utilizes quadcores.

I would pick up the E8400 and a good cpu fan for a solid overclock of 4ghz+
August 14, 2009 9:10:12 PM

Go for an AMD triple or quad core. I've had four intel dual cores and eight 775 motherboards because the intel chipset kept f@#king up or suffered from voltage drop and wouldn't boot. I went to an AMD quad at the end of last year and haven't looked back. It's so much better in game play than the dual core intels and a lot more reliable.
August 14, 2009 9:21:58 PM

Actually COD4 and COD5 are optomised for quad cores and will use 5 of the cores in my dual socket Opteron. If I had a more powerful graphics card it would most likely use more cores.
August 14, 2009 9:27:37 PM

I7 drops 12fps from 1280x1024 to 1068x1050
E8600 drops 2fps from 1280x1024 to 1068x1050

I guess it does use quads....now if they will patch it to take advantage of high-end GPUs and SLI.

I would still like to see benchmarks with higher resolutions.....say 1920x1200 (what I game at)

August 16, 2009 5:50:33 PM

Just to add this to the equation

the prices for E8400 and Q9400, here in Croatia are identical

That's got to be the best compromise, only 400mhz off clock speed wise.

I have Socket 775 e8400 build I keep around for a 2nd or spare PC. The mobo is a GA-P43-ES3G. I scan for Core 2 Quad CPU, the Q8400 is the lowest priced but I would not call that reasonable. Do you have any leads? The e8400 remains in PC til I locate a fire-sale Core 2 Quad. Maybe Q9505? When I review " CPU-Benchmark" I wonder why I would invest anymore into the Socket 775. By the way, I am a video trans-coder with a i7-950 Build, w/ 6Gb ( 3x2Gb ) 1333Mhz, GTX460 336 stream processors, SSD, HX750, Blu-Writer and Zalman 1000+. After all that , I find the i7-2500 outruns me. It doesn't matter because blu media is @ 2x,4x, & 6x with best quality copies in @ 1x. Sorry, did you sport any low priced Core 2 Quads?

i also want to buy pc how about dell optiplex 760 with e8400 4gb ddr2 ram?it will work better then q8400 in GAMING?
