AMD Athlon X2 4200+ Upgrade

Hi guys, I've found your site here to be very informative so thank you. I have a problem that I can't find a solution for though. I have a MCP61SM2MA-RS2H Mobo and am looking to upgrade from my AMD Athlon x2 dual-core 4200+ AM2 CPU. It's currently at 2.2ghz and I think I need 2.8 or higher to do what I want to.

My issue is when I'm recording gameplay with BlackMagic Intensity Pro in 720p my CPU usage hovers between 85-100%. This is causing me to drop frames frequently. I have done all the searching I can on the product forums of the recorder and elsewhere to come to the conclusion that my CPU just isn't fast enough to process what it is trying to do so it is dropping frames.

Can I ask if there is a compatible CPU upgrade that will give me around 3ghz under $100? Thanks in advance.

Edit: Just to add to the previous when I record in SD (480i) the CPU usage runs between 30-40% unlike the HD (720p) at 85-100%. As for memory usage it stays the same at around 1GB. I have 2.5 useable GB so I think I'm good there. Graphics card is Nvidia 9500GT. Thanks again..

This is the CPU support list according to Foxconn. Hope it helps
Maybe a 5400+ or 5600+ from ebay would be the ticket.

Go ahead and list the rest of the parts attached to your motherboard.
We might be able to get you into a new motherboard & CPU for under $100 while reusing the rest of your parts.

Plenty out there http://www.google.com/search?q=how [...] .microsofta&ie=UTF-8&oe=UTF-8&startIndex=&startPage=1
