Hi. No it is a "modern" one as I posted - a dual core AMD X2 6400 running at 3.2 Ghz. It should have absolutely no problem playing h.264 HD content- and thi sis not even that.<br><br>I think it is the ATi video drivers myself. I am just wondering if anyone can verify this before I go buy a new card. Are the fglrx AVIVO drivers really THIS bad?<br>

If it's an AMD64 original, it's single core. But you might get more <br>grunt out of it by rebuilding it as a 64bit system if it's in 32bit <br>currently, should give you around 25% more grunt. But I've heard it <br>
