A little advice on upgrading (GFX/RAM/CPU)

Hey,
I'm pretty amateur when it comes down to up upgrading my computer so Can you guys please help me a little as I wouldn't want to buy something that's not going to work.. anyways..

My System:
Motherboard: AsusTek M3A32-MVP Deluxe
AMD 790FX chipset
Processor: AMD Athlon 64 x2 5200+
Ram: 4GB
Graphics: NVIDIA GeForce GTS 250

So it's a little old now however I'm thinking of upgrading Processor, RAM and Graphics card as it's long over due, Here's where I could do with a little help, firstly will they be compatible and secondly your thoughts on them and/or is there a better option?

Here's what I was thinking about upgrading to:

RAM:
ebuyer[dot]com/264750-g-skill-8gb-2x4gb-ddr3-1600mhz-ripjawsx-memory-kit-cl9-9-9-9-24-1-5v-f3-12800cl9d-8gbxl
G-Skill 8GB (2x4GB) DDR3 1600Mhz RipjawsX Memory Kit CL9 (9-9-9-24) 1.5V

Processor:
overclockers[dot]co.uk/showproduct.php?prodid=CP-314-AM
AMD Bulldozer FX-4 Quad Core 4100 Black Edition 3.60Ghz (Socket AM3+) Processor

Graphics Card:
videocardshop[dot]co.uk/viewproduct.aspx?part=HD-585X-ZAFC
XFX Radeon HD 5850 725M 1GB DDR5 DUAL DVI DP HDMI PCI-E

Sorry I tried to make them links however I need over five posts.
Any help/advice would be greatly appreciated,
Thanks.
 
It also will not support the new FX (Bulldozer) CPU's from AMD either.

The motherboard will fit a up to X6 core Phenom II 1100T though, so if you want to upgrade on a budget its worth a consideration. (The 1055T/1075T/1090T/1100T all work with BIOS revision 2202 onwards).

If I was you (and motherboard replacement was not possible due to budget constraints), I would go for a 1055T hex-core and overclock it with a decent aftermarket cooler. All the hex-cores are the same, only the clock speed differs so its quite possible to overclock it to 1100T values and beyond.

DDR3 RAM (as stated above) will not work with your current motherboard.

Also, the HD58xx is older now, I would consider a HD6870 instead. Its a couple of £'s more, but uses less power and is more efficient.

What power supply is being used with this computer?
