What CPU should I upgrade to?

[liam_abrown]

First of all sorry for the essay but I want to be thorough so I get the correct advise.

 

I recently bought a Blackmagic Intensity Pro capture card. I have been in contact with Blackmagic and they were reasonably helpful but anything other then there devices they didn't seem to know much about.

 

I am trying to capture at 720p - 59.94fps - compressed motion JPEG as this seems to be a good standard of capture.

 

We have established my HDD write rate needed to be 13.5MB/s+ and it is always in excess of 89MB/s so I can't see a Raid 0 making a difference. The capture program does not seem to RAM intensive and yet I was still losing frames. So I watched the CPU usage after hitting record and it was going straight to 70% and within 10 seconds to 100% and then dropping frames obviously.

 

My question is I need a new CPU so what would your recommendations be for my current motherboard Gigabyte M61PME-S2P (rev1.0)

 

GA-M61PME-S2P (rev. 1.0) - GIGABYTE - Product - Motherboard - Specification

 

After having a quick read and seeing this on my motherboard spec I am concerned that upgrading would actually slow me down due to bus:

(Note) If you install AMD AM3/AM2+ CPU on AM2 motherbord, the system bus speed will downgrade from HT3.0(5200 MT/s) to HT1.0(2000 MT/s) spec; however, the frequency of AM3/AM2+ CPU will not be impacted.

 

I am reasonably computer literate and tell me if I am wrong but this means if I upgraded to say a AMD Phenom II Quad Core I would actually lose speed due to my motherboard slowing bus down.

 

My current set up is:

*Gigabyte Technology M61PME-S2P motherboard

*AMD Athlon II x2 dual core 245 - 2.9ghz - 2mb L2 cache processor

*Kingston hyper X 4gb (2 x 2gb) DDR2 800mhz dual channel ram

*ATI Radeon 4850 GDDR3 PCI express - 512mb graphics card

*Seagate barracuda 7200.12 - 500gb - 7200rpm - 16mb cache - average 8.5 seconds seek time

*Corsair VX450W power supply

My personal feeling is the drop in bus speed, may be irrelevant in this case, but I am no expert, there may be someone else will have a better knowledge and can reply with a better answer.
