Hello,


I have an Intel E6600 dual core, 4GB RAM, EVGA 8800GTS, ASUS P5N32E-SLI, Philips Blu Ray SPD7000. Running at 1920x1440, 32-bit color depth, CRT, via VGA @ 72Hz. When using PowerDVD 7.3 Ultra and, for example, "Casino Royale", I get between 40%-60% CPU utilization. Playback is smooth. Just wondering if the CPU utilization is typical.


Has anyone tried PowerDVD with an Intel quad-core? If so, any performance improvement or woiuld the quad-core be a waste of money?

While I like our quad-core solutions in general, for home theater use you'll get way more bang for your buck by swapping your video card for one with H.264 acceleration, like the Nvidia 8500 and 8600s. Your gaming will suffer, but your home video CPU utilization will drop through the floor.

Thank you all for the tips, I'll give an 8600GTS a try and see what happens. It'll free up a PCI slot as well since the 8800GTS is double width. As I have now read, the 8600 has built in Pure Video HD so that is a nice bonus.


Maybe I'll head for quad-core when the prices drop a bit.


This machine is not a gaming machine, it is intended for HTPC so maximizing HDTV, DVD, HD disc formats is the primary concern.

The 8600GTS is going to help you a lot! I have one in my system, running E6300, 1gb ram, and CR was much lower in CPU usage than the 40-60% you were seeing. I can re-test it, but it seems like it was about 10%. I will check the usage when I have time, but tonight's menu includes DMC and COTBP.

Since you have already spent the big bucks on the 8800, why get rid of it? So what if your cpu has 40 to 60 percent use, you still have plenty of horsepower to spare and most importantly, you did say you have SMOOTH PLAYBACK. Also some like Owen say they get better pq with the 8800 over the 8600 provided they have the horsepower to do so which you obviously do.

My rig is similar to the OP with two difference. I have half his ram and i have a 8800 GTX running 1920x1080p (native resolution of 52" lcd flat panel).


Rarely have i seen util go > 30-35%


EDIT: BTW this is on XP (where nvidia doesn't have purevideo HD acc on 8800)

Thank you for the advice and another point of view. I will give the 8600GTS a try and see if there is any benefit or detriment to CPU/Picture Quality, etc. Maybe it's just me, but I think letting the card do the work rather than the CPU could be a good thing -- as long as the card does it well. I do note that WMV-HD only utilizes about 20% CPU. In any event I'll update this thread with the results.

The CPU will drop no doubt (at least in Vista). It'll be

I am trying out the EVGA 8600GTS and am amazed. No other hardware has been changed. Resolution, color depth, refresh, Vista configuration -- all the same. Same 158.18 nVidia driver. For HD titles, CPU has dropped to the teens, low 20's in CPU usage -- a drop of 40%. HD movies look wonderful (Blu-Ray "Casino Royale, HD-DVD "King Kong"). Will evaluate HD TV signals but for now the non-HD digital TV looks great. SD DVDs and WMVHD appear fantastic. This card cut through the HQV test disc like a hot knife through butter. No games on this system and it will not be used as such. It is noted that in the Vista Performance Information Gaming Graphics dropped from a 5.9 to 5.6. Obviously there's a tradeoff but for HTPC Video performance, a CPU challenged HTPC box might benefit greatly by using the EVGA 8600GTS. The EVGA 8600GTS is HDCP-enabled. Keep an eye open for HDCP-enabled. It is my understanding that some of the 8500 and 8600 series cards do not all have HDCP.


This card is a winner.
