I'm currently using an i3-4130 for a combined system using onboard 
graphics no worries. It easily plays 720/1080 on my 32" tv with a good 
level of deinterlacing. I'm pretty sure I've got it set to opengl 
renderer rather than vaapi for the better deinterlacing support.
I occasionally get a little bit of tearing but it's only because I know 
what to look for, my partner's certainly never noticed.
I'm running linux mint 15 with xorg-edgers-ppa-raring graphics drivers 
although it's been a while since I updated them.

I occasionally get some minor freezes during playback but I'm quite 
certain this is due to either recording 4-6 programs at once in the 
background (usb and pci dvb recorders) and sometimes from mysql maxing 
out the cpu, haven't got to the bottom of that one.

The same system also runs file server duties and acts as a crashplan 
server for backups, this does take noticible cpu when looking at htop 
although I don't think it's ever affected playback.


I was previously running on an i3-530 in a basically identical setup and 
it worked just fine for the same kinds of playback.

Based on this I think you would be fine with the celeron, it looks 
pretty similar according to the comparisons really. Most likely 
difference could come from the number of threads, basically having to 
share the two threads between frontend, backend, mysql and system may 
get a little tights, but when I'm watching and recording shows, htop 
usually just shows two of the threads in high use on my system anyway, 
there's often a couple of threads pretty much idle.

Cheers,
Andrew
