As long as you have a decent GPU (HD 3200, GF 8200, Intel 4500) 1080P has been shown to run fine on even the single core Atom platform.

i found BOTH AMD and nVidia cards (HD4850 and GTX260) to stutter when rendering a variety of files in 1080p... typically x264, AC3, MKC files using MPC-HC (which is the ONLY way right now to use acceleration in files). Most distinct of those was xmen, which stuttered a whole LOT. When I turned off the GPU acceleration and let my E8400 take over all stuttering disappeared (but my CPU usage did go up somewhat)

GPU acceleration worked fine for me with no stuttering on an 8600m GT, 9800gt, GTX260, and a 4890, so your issues were probably caused by something else
Also, MPC-hc isn't the only program that can use hardware acceleration...

show me one other program that can accelerate an x264 MKV file. Also, it worked fine for some files, and it worked fine for 720p and most 1080 files. it is only some 1080p x264 files that had issues (during action packed scenes), I know what I am doing here.

VLC for one, Windows Media Player for another...

mpchc works with older cards, like nvidia 7 series.

Not true
"Unfortunately the MPC-HC decoder only supports the "bitstream mode" at this stage, which means that only the most recent graphic cards are supported :
nVidia series 8(9)xxx for H.264 only
ATI Radeon HD series for H.264 and VC-1 decoding"

It is hard to demonstrate/measure a 'pure' CPU decoding in a modern system, so yes in all practicality E8400 should suffice for 1080p. But in theory it may not, depending on how a movie is encoded.

I used CoreAVC on a 2.8 Ghz Pentium single core, (forgot the code name) and it played back butter smooth. Onboard GMA 915 video btw. Brute CPU/GPU strength is one way to go, but look into optimized codecs as well.

With those settings cpu usage is about 10% on a quad core. Q6600. I can't use DXVA with this card as it isn't supported. nvidia G80 core.
I tried coreAVC and it was actually slower using up to 25% cpu .
Still I am happy with the way it plays.
