Hey All

I want to upgrade my CPU.  Just wondering what you would recommend.  I don't need to go for a low power cpu because my case is large with plenty of fans/airflow and is already quiter than the fan in my AV receiver.  So No point spending the extra $$$ on a low power chip.  I'm currently using an AMD X2 4200+ with stock cooling.  Using coreavc my cpu useage is 80% on live TV (1920x1080 Display) but occasionally it is a bit sluggish so i want a bit more spare cpu power.

Not sure if a triple core would be faster than a similar priced faster dual core.

Was thinking of

 $100 = X2 5000+
 $145 = Phenom 8450
 $158 = X2 6000+




HTPC: Intel i3-2100 / 12GB RAM / AMD HD7750 / 480 GB SSD / 58TB Storage / MediaPortal / MadVR / Win10
AVR: Pioneer Elite SC-LX87 220W 9.2 Ch AVR
Speakers: Wharfedale Jade 7 Fronts / Jade 2c Center / Jade 5 Rears
Subs: iNuke 3000dsp 3000W proamp with 4x 15" JBL Sealed Subs
Display: Samsung 60" UA60H6400 LCD TV

Have you considered getting a video card instead? That will offload the 80% usage down to 10%, so the interface will be a lot more smooth.
However if you're going to continue to use CoreAVC software decoding, a triple or quad core would be of benefit to you.
But for single threaded applications its likely you wouldn't notice much difference - though im not sure how 1 core on that X3 compares to 1 core on the 4200.

Agree with the above statement.. leave the CPU it is fine for a media centre. Spend the money on a video card that fully supports hardware decoding instead. You will also get a better picture if you use hardware decoding rather then software decoding.

when i tried a 8600gt in there it kept crashing in xp with hardware acceleration of progressive channels (interlaced was fine)
I tried a fresh xp install each time, with 3 different versions of nvidia drivers and latest pdvd8 ultra 2021 and MP RC2.
I dont want to go vista because of the evr flicker.
If i do go vista i can just use the onboard for hardware acceleration, but i find the evr flicker unacceptable.

Hardware acceleration is essential if you want to watch Freeview|HD with a good quality picture. A codec such as PowerDVD7/8's H.264 one or Arcsoft TotalMedia and a GFX card capable of H.264 hardware decoding isn't an optional extra, it's a prerequisite. Software decoding simply doesn't cut it, particularly witth 1080i content.

You have a board capable of hardware decoding but un fortunately ATI's Catalyst drivers still seem to be broken so it doesn't work properly with interlaced content.

What you mean? EVR is a far superior renderer, this is the first time I've ever heard of a flicker issue.

If you have evr renderer you get flickering of the OSD when you have video running.
It is probably not gonna be fixed until MP2 release

http://www.youtube.com/watch?v=FibgNXk-16c

Flicker comes in at 39 secounds
The video title is ati-evr-flicker, but the problem is with nvidea cards too
It happens if you have the OSD and video displayed at the same time
(he has tv guide running and video in the corner @ same time)

EDIT: I see you have GBPVR, it is a MP problem

$100 for Nvdia 8500 or 8600 will be much better idea.

I have a s939 Athlon 3800 X2 and it runs at about 10-30% on TV3 with my 8600GT.

But if you do upgrade get the Phenom seeing as power is not an issue. my 10-30% is on both cores so having one extra will be a great help.

Cheersdb
p.s. I can rip a Blu-ray disc while watching Freeview HD with no stuttering problems so I really think you need a Video card upgrade.

Since you only have XP the EVR issue won't affect you anyway. Hardware acceleration should be working perfectly with XP and VMR9 and an 8500/8600.

New one came out a couple of days ago and fixed the HW acceleration issues i was having (dropping frames). After you install them uninstall PhysX that comes bundled if you don't play PhysX games (or any at all).

Hi -sounds like your Motherboards chipset has compatibility problems with Nvidia GPU's?

Have you googled this to see if others have this problem -or maybe it's a fault specifically with your board?  I have heard that ATI GPU's are likely to work better with AMD chipsets (not surprising really) so maybe you want to look at an ATI card?

In spite of what some people try to tell you on this forum, it is a fact that I have a Sapphire HD3850 working perfectly with hardware accelleration -and it's a AGP variant too.

ps. using Power DVD 8 Ultra's H.264 codec and the latest ATI drivers.

No point in changing to another ATI video card.  Hopefully catalyst 8.10 will fix it, as each catalyst upgrade seems to get closer to fixing things.Other people have put in 8500GT/8600GT into 780G mobo without problems, but there were in vista.
