thanks for the quick reply guys! im actually kinda thinking between AMD Phenom II X2 555 3.2Ghz and AMD Phenom II X4 970 3.5Ghz! is the power supply still enough? and i have an msi K9N6PGM2-V2. will it work?
with a high end desktop, 30% cap aging, 3 92mm fans, 3usb devices and the x4 970 you'll be looking at a minimum power usage of 380w recommended of 430w. So you are still good but you will need to upgrade if you go any bigger on the video card end... which Im gonna assume you want to do soon.
the x4 925 would put you at 348min 398recommended.
according to the msi website (which is horrible BTW) that board is an AM2/AM2+ board But it is AM3 ready (meaning you will need a bios update ... or to purchase one that has already been updated) to run an am3 cpu. Your video card will work though ... the one pci-e x16 slot you have is 2.0 and so is that card.
just be aware that you wont be able to boot with an am3 cpu in that board by default unless you check first and it has the right bios revision out of the box to support the am3 cpu. from what I can glean from the website...did I mention how bad MSI's site is? cause its bad... the bios revision you will need is 2.0 or higher.
I dont think it will turn on with an am3 cpu in it prior to flashing the bios. Meaning you will have to put an am2 chip in it, flash the bios, then put the am3 chip in it. Maybe if you can find out what bios it has on it prior to purchase you wont have to worry but good luck finding a website that lists the bios revision.
