This barebone setup comes with RAM that is faster than your existing RAM and I wouldnt mix RAM speeds.
Yesterday I was looking at a similar upgrade myself as for I am running Athlon II x4 620 2.6Ghz AM3 CPU in a AM2+ motherboard that is at its Memory Limit of 4GB of DDR2 800Mhz. I too have gone the path of small upgrades over time in which a motherboard upgrade is needed to upgrade further.
I found an AM3+ mATX motherboard that supports 16GB of DDR3 and was going to go with that solution, but was advised to avoid MSI Brand and go with ASUS or Gigabyte Brand. Now looking at your post,
I have to Thank You for posting this, as for the board you linked is a perfect match for what I need since it claims to support 16GB is an AM3+ mATX, and has dual PS2 keyboard/mouse ports to work with my 4-port older PS2 type KVM!
With this bundle everything you have will work except I wouldnt mix the 1600Mhz with 1333Mhz RAM. It comes with 1 x 4GB 1600Mhz RAM stick. I'd pick up another 4GB 1600Mhz stick and have 8GB of faster RAM if you want to use the stick that comes with this. Otherwise dont use the 4GB stick that comes with this and just move your existing 8GB RAM over at 1333Mhz. * Sometimes you can mix fast and slow RAM and have 12GB and the faster 1600Mhz stick will downclock to 1333Mhz, but this is not an option with only 2 RAM slots anyways.
As for myself I want to make the leap to the maximum memory of 16GB of DDR3 1600Mhz, and use the rest of my existing hardware including Athlon II x4 620 2.6Ghz AM3 CPU until the quadcore isnt enough and upgrade further. Now that I know what board to look for I can try to find the board alone and match it up with 16GB 1600Mhz RAM and move my CPU over to it.
My current setup is:
AM2+ Biostar MCP6PB M2+ Motherboard
(Originally a dual-core Sempron x 2 2.00Ghz, barebone $65 Motherboard / CPU Combination bought in 2008)
Now an AM3 Athlon II x4 620 2.6Ghz ( from a free upgrade out of a bricked HP that I yanked the CPU out of that was being thrown away a year ago)
2 x 2GB Corsair 800Mhz DDR2 RAM ( Ram I bought for $10 off my brother )
PCIe Radeon 5450HD 1GB DDR3 Video Card ( $30 video card )
OCZ Agility 90GB SSD SATA III running at SATA II backwards compatability ( $65 back to school Newegg special )
Seagate 500GB SATA II Hard Drive ( was found thrown away dead, sent it back to seagate for warranty replacement when i found it was still under waranty, my cost = $6 shipping - Got replacement drive 2 weeks later
)
----------------------------------------------
New Build will be:
Athlon II x4 620 2.6Ghz in an AM3+ Motherboard
( I want the AM3+ for processor support for the FX chips when I get one cheaply, it was convenient that my AM2+ supported the AM3 that I got for free. Maybe having the AM3+ will allow for another free future upgrade)
16GB 1600Mhz DDR3 Corsair RAM
*All other hardware migrated over drives & video card.
And the upgrade to Windows 7 64 bit
