What AMD CPU and Gigagyte Motherboard - Help!

Hi Guys.
I need some major help here

I am switching from INTEL to AMD so I am not into the AMD terms.

The motherboard listed below seems to be a good enough for my needs, not sure what NFORCE4 means, but somebody told me to make sure it was nforce4???


MOTHERBOARD
*************
Gigabyte GA-K8NF9 AMD 64 socket 939 NVIDIA NFORCE4 DDR 400/333/266 8CH AUDIO Motherboard

Possible CPU's
************
1. AMD Athlon 64 X2 4200+ Soc 939 DUAL CORE $551.05
2. AMD Athlon 64 X2 Dual Core 3800+ Socket 939 CPU $455.50
3. AMD Athlon 64 3800+ CPU with Heatsink & Fan Retail Box $507.50

Prices are NZ dollars, just there as a reference point.

ANyway, couple questions please

1. Will all 3 CPU's work with this motherboard?
2. Can I use my exisitng AGP 6600 nvidia graphics card with this mboard?
3. Does this board have a built in graphics card? is that what the nforce4 is?
4. Why is the price of the none dual core cpu more than the dual core one? Faster but only one core? Any ideas?
5. Does 4200+ and 3800+ equal to 4.2Ghz and 3.8Ghz speeds like INTEL CPU's use?

Thanks for any help, I am really lost here 8O

cheers

Thanks

Would that motherboard and the Dual core 4200+ be a good combination? Any issues using them together?

WOuld someone recomend something different?

SO far I'm going with
Gigabyte GA-K8NF9 AMD 64 socket 939 NVIDIA NFORCE4 DDR 400/333/266 8CH AUDIO Motherboard

AND

AMD Athlon 64 X2 4200+ Soc 939 DUAL CORE

I am definately a multi tasker.

cheers

Whoa thanks Pat, great info!
Feeling a little dated now with technology, fell a little behind.

I will get a PCI-e graphics card then. WIll see if that card you recomended is available locally.

My 6600GT card will have to go to my TV/Internet PC then.

I currently have two 250 gig 7200 rpm IDE drives and one 80gig 7200rpm IDE drive.

C: = 80gig
D: = 250gig
E: = 250gig

Does this MBoard support my IDE drives?

God, am I that outdated?

:-)

1. Gecube ATI X600XT PCI-E 256MB DDR
x16 PCIe TV-out $171.65
2. Gigabyte GV-RX70256D ATI Radeon
X700 256MB PCI-E X16 $187.50
3. GeCube ATi Radeon X850XT PCI-E 256MB
256-bit DDR3 Dual DVI-I Vid $395.80

Well those 3 are what I can choose from.
Number 3 is pushing it over the budget.

To get USD multiply the figures by 0.75

But am interested in your thoughts as to which one I should get?

Thanks

I would go for an nvidia card. If your budget allows, you can pick up a 7800GT PCI-E for like 295. Here's a link. The rest of that build looks pretty good man. Good luck with it.
