Upgrading Computer Parts - Need Help

[mancream]

Okay, I have done some research on the ATI Radeon HD 4870 2x. I am probably able to add more cash probably I'll waste about $1900-2000 max. Not sure what kind of motherboard to choose. My harddrive is Serial ATA, Idk if my dvd\cd drives will be compatible, I don't know these kind of stuff =\

I'm sure I'll need a new power supply, not sure what kind and how many watts and I'll probably need some fans or coolers for all these parts. Any other parts I need that I did not list other than hard drives and cd/dvd drives? Not sure if these are good but there you go.

Help me out people Thanks

Hmm everything seems to be compatible. Although I'd hold up on the 2nd Video Card as it seems that there are issues with different things. You wont need a CPU fan as the CPU you chose already has one and a heatsink. You'll probably wanna get more fans for the computer though.

What kind of fans for the parts? Well the video cards are joined, What video cards should I buy? I heard those single 4000 series are good.

Thanks.
