Since no one seems to have actually answered the original question, i would put the 360's hardware performance as such:

GPU - R580 clocked at about 400-450mhz
CPU - Core 2 duo, around 2.4-2.8ghz

kthxbai.

what's wrong with u, TS

Craps....

For me i think pc is too complicated in hardware and software form made gaming is not as efficient as console which is built for gaming.Pc os alredi making the game is not as smooth as what u can see the diffrent in vista and xp. And 1 more thing the driver is play the important rule in pc too.But in console all is unified.So the game producer can fully ultize the hardware in console. But in pc diffrent hardware diff os diff driver.

TS , how about comparing games ?

Since both plaform have the same game Gears of war , why dont you guys state out what is the min spec that can play the game in high settings with a constant framerate of at least 60?

Since console are made to have 60 FPS , then apply this to pc too

Well , i cant give opinion because i am using  8600 GT with duo core 2.0 , and have the gears running at most at 40 FPS and most of the time drop to 17 FPS

This is indeed playable , but its lag...........

Put aside games like crysis , only focus on games out on both platform

I know people are going to argue about the games on difference platform are totally difference , but whats the point knowing what spec equivalent to 360?

Its the games we are talking about, and surely , even you know that , you will need more juice to play games smoothly on pc even if they are the same game on difference platform.

I thought GoW on X360 running at 30 FPS?

For X360, Microsoft requires the games to have 30 FPS minimum. So the console is not designed for 60 FPS.

Consoles have fixed HW, so in time the dev will probably optimize what they can put in the games - better coding = better performance.

Anyway, for TS:-
Processor -> Tri-Core Power-PC @ 3.2GHz each w/ 2 threads. Faster than Core 2 Duo, I think.(Notice that current Core2Duo proc has 1 thread for each core only)

GFX: Probably based on ATi 1900XT, but customized with eD-RAM. According to MS, it enables free 4xAA. But in reality, 10 MB of eDRAM is not enough to support 4xAA @ 720p resolution.

RAM: 512MB GDDR3 RAM - less than PC's, hence there's some low-res texture in games. It's used as main RAM and Graphic RAM.

those console graphic 50% depents GC 50% is depents on CD...dun forget xbox 360 is using HD-DVD!...HD-DVD is 50% more clear than DVD....Even Xbox 360 is using Nvidia7900XT as GC...result out also same as 8800GTS.....WHen i play Ghost Recon Advance Warfighter...in Xbox graphic = PC Very high setting (PC i used 8800GTS SLI result = same graphic to Xbox 360 HD-DVD result)
PS3...DO it got GC..i tell u it dun have.....WHY PS3 graphic so so Pretty?

PS3 using 8 Extreme Processor (Normal PC is 5Ghz super max OC with nitrogen liquid) But PS3 Processor is 20GHZ=2Trilion per second speed without OC MEANS 8X20 GHZ = 160GHZ PROCESSOR in PS3!!!!! plus using Blue-Ray Disk...150% more clear view than DVD....PS3 no GC but result same to 8800Ultra Triple SLI result (Do u guys see Grand Tusimo newest one? play games like see a Movie...SO SO  real....Even 8800ultra triple SLi also cannot do that maybe.......
Back to X-box 360....it using HD-DVD and x-box processor is 1 trilion per second speed...means 10Ghz Processor without OC....so PC how to beat those console ? Console no need GC at all using it processor power can make ur games see very nice and Very Fast!!!

DO u see Console games make u lag before? LOL!!!!
Conclusion:Console gaming they no depents on GC they used quality on HD-DVD or Blue Ray Disk to win PC......and Processor too~~~

Here the Link to let u see :PS3 power

Console Graphic Tech is far more higher than PC graphic setting.......

Lol, how can I miss that post..

Anyway, X360 doesn't use HD-DVD as their storage for games. It's still using DVD.

Oh is it 30 ?

Because the Modern warfare are said to have constend of 60 on both 360 and ps3 , anyway , we wont see a difference between 30 and 60

Well , the question comes back

What min spec is required to play Gears , Blacksite , Stranglehold etc at min 30 fps?

Well , for those who have 8800 GT , is it enough? or 8800 GTX Sli is needed( I think this is way too high )?

As for ram and the processor etc......
