What order should i buy my parts in?

[powsplatboom]

I plan on buying a new computer in the very near future, but i don't currently have the money to buy the whole list of parts at once. I'm looking to put the newer parts in my older build as I go. My current pc is as follows:

cpu- Intel core 2 duo e8400
Graphics card: Nvidia GTX 560 ti (will be in the final build)
Hard Drive: Seagate Barracuda 500Gig
Power supply: 580W single 12v rail (don't have the official name and have no reason to open my case and find out)
Mobo:G31t-m (American megatrends board)
RAM: 4gigs DDR2 (2x2gigs)
case: falling apart full tower. really old.
cpu cooler: stock
OS: Microsoft windows 7 home premium

My new build will be as follows:

Case: Corsair Carbide Series 400R
Mobo: ASRock 880G PRO3 AM3+
Power Supply: OCZ ModXStream Pro 600W Modular High Performance Power Supply
cpu: AMD FX-4100 Zambezi 3.6GHz (3.8GHz Turbo) Socket AM3+ 95W
RAM: CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM
SSD: Corsair Force Series 3
OS: Microsoft Windows 7 Home Premium
cpu cooler: COOLER MASTER Hyper 212 EVO

Also, any suggestions on where my new build might need revision?

Well... upgrading from the Core 2 Duo to the FX-4100 won't be the dramatic improvement you're expecting - and most motherboards won't support FX natively out of the box - you have to have an older Phenom II processor and flash the BIOS, then install the FX. It's a huge pain, I know.

Now upgrading to an i5-2500K will see a huge, dramatic improvement over your current build. Here's a few recommendations I'd make:

Case: Leave it as is, Corsair makes awesome cases, among other things.

PSU: That wouldn't be much of an upgrade. What you want to look for in a PSU is efficiency when handling that much wattage. This would probably be a better choice: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087

SSD: I like Corsair but I'd really research the Force 3 before you buy it - there's been a lot of compatibility and BSOD issues with it. Check the official Corsair support forum before you buy. I really like the Crucial M4 - it's been a really great drive so far.

Motherboard: These would be better buys than the AMD 880 :

CPU: This would be a far better option than the FX-4100: http://www.newegg.com/Product/Product.aspx?Item=N82E16819115072

RAM: If you're going to be using any sort of cooler, you need to make sure you get the low profile Vengeance RAM - those tall heat sinks can make installing coolers extremely difficult.
