I just got a Foxconn M7VMX mobo with a Pentium Core2 Duo from a friend to replace my old (loud and hot) P4 setup for the HTPC in the bedroom. I'm using Media Center in Win7 (32bit by may upgrade to 64bit). As far as the new mobo is concerned, I'm very pleased with the speed and how quite it is. Also, it handles full sleep mode much better than my P4 did.
The one minor problem I have is the new mobo only has VGA output since it's got the GeForce 7050 onboard. For the most part this does decent with Live TV broadcast and NetFlix streams. The issue I'm having is that when navigating through the NetFlix Media Center guide it's VERY laggy. For example, it take 5 to 10 seconds to move from one selection to the next on the queue summary section. Once you start the stream it's fine.
My first thought is to replace the onboard video with a cheap PCIE card. I would use the one out of the old P4 but it's high end AGP. I was looking at getting this ASUS Radeon HD 5450 to see if that would fix the problem, but I'm not certain it will.
So really I have two questions.
1. Has anyone seen similar lag from the NetFlix extension? If so, how did you fix it?
2. Is the 5450 a good cheap replacement for the 7050? I'm trying to stay under $50 and fanless.
