Upgrading CPU and Motherboard

[Nick298310]

Hi all,
I'm new here and this is my first post. I look forward to staying on these forums.
Anyway, I would like to see your suggestions on how I can upgrade Motherboard (and probably my CPU) but also keep the rest of my system. I would normally do this myself but since my PC has some fairly old parts (3-5 years) and some brand new parts in it, I am questioning the compatibility.
I would be spending about $150 and under the Motherboard. The CPU is optional (i have a functional CPU but i would appreciate an upgrade). Price range for the CPU is $150 (give or take 10 or so dollars). In total I have have 400 bucks to spend but I would only like to spend 300 or so. If you find a really good deal, I am willing to spend all of the 400, but that is only if you find: quiet, powerful, and compatible parts.

My SystemPLEASE REPLACE THE CPU AND MOTHERBOARD WITH YOUR SUGGESTIONS)
Motherboard: ASUS D945PVS (Pentium 4/D motherboard Made in 2005-6)
CPU: Intel Pentium D 830 (Dual-Core 3.00GHz)
RAM: Corsair 2GB DDR2 (will i need to upgrade the RAM too?)
GPU: HD 4670: 1GB DDR2 (Its a fairly good card for only 80 bucks)
OS: Windows 7 Home Premium

Here are my prospects that I need help choosing from.
