Finally got sick of my old, bulky, noisy, overclocked Q6700 being my HTPC and did some parts shuffling and some purchasing.
The Q6700 is back to being my main workhorse, with my old 4870.
I had been wanted to build an ITX system for quite some time, so I went and picked up:
CM Elite 120 Advanced
MSI H81I
Pentium G3420
4 GB DDR3 1333
And slapped it all together with my media drives and the Quadro 4000 I was given as payment for watching somebody's house while they were out of province. Cost me $272 CDN all told, and it now fits in my TV stand and doesn't make the girlfriend cringe at the size.
Honestly, with the exception of "many-program" multitasking, that Pentium is just about as fast as the old Q6700. And since I can only get about 3.15 Ghz on the Q6700 overclocked, the Pentium gets better single-threaded performance.
