Technically speaking the Xbox 360 is still technologically superior to PCs in the graphics department and was superior at launch in the CPU department, however it still depends on whether anyone can exploit those advantgages.
Not true at all. I use owned one up until a couple of weeks ago and recently sold it on Ebay because I just didnt see the need in having it along with my PC.
I have pretty much played every game thats available for both on the 360 and the PC. COD2, Prey, Condemned, Oblivion, Hitman Bloodmoney. ETC...
The PC versions have a good lead over the 360 counter parts with higher res textures, the PC does AA better and AF plus even with these added features I get far better framerates on my PC.
You're missing my point, and yes I know it was kinda unclear, but I tried to focus on the specific aspect.
Something can be technologically superior, without actually exploiting the full capabilities, AF being a perfect example, Xenos+CPU could do it, but is not. Don't get me wrong there's little I've seen on the X360 to say X360>X1900, in fact nothing, but techologically speaking Xenos>X1900 in most aspect with a few small exceptions like AF (which isn't necessary if the devs specifically gear their games for the consoles, but since they're lazy you notice the lack of AF).
B3D's feature list does a good job of exposing the differences;

I dont know why but when it comes to AF filtering the 360 games seriously lack in that department which leads to muddy looking textures which just kills the whole experience for me.
No support for Trillinear AF in hardware (billinear only IIRC) for the Xenos, but if the devs did a better job with the textures at the same res it would look the same, what AF also does is enhance beyond reference, so high AF can make a good picture look better, but occasionally make them slightly artificially worked up.
And as for the CPU in the 360 it was actually outdone by PC Cpu's a good while before it even came out. It has been explained in tech articles about the 360's CPU being able to only read inorder code vs out of order code on your typical intel or amd cpu. The performance of the 360 CPU is about equivilant to a pentium 4 1.5ghz cpu.
Well it's a question of use, for what it's geared to do it was way ahead on the technical side, but as a general purpose CPU it wasn't as flexible, but it was using far more advanced techniques at the time of launch, which are now being carried over into other areas.
Another article also proved it to be only roughly 2 times the power of the Xbox CPU.
And this is the thing I was trying to stress, not power but technology superiority, speed is a slightly different function and I easily grant it's not very powerful in raw power, just like the Xenos, but they were the cutting edge of technology at the time.
I'm in no way saying Xbox360>PC nor Xenos more powerful than X1900 (in fact usually argue the opposite) but the Xenos is definitely technologically more advanced, but that's not the same as better or more powerful.
It's like the GMA965/3000 may be SM4.0 compliant and may have some tehnological advantages over many current VPUs, but it likely won't game near an SM2.0 X700 let alone a GF7600/X1650 or higher, and can't use SM4.0 features in games any more than as a slide show feature. Sorta same thing IMO.
