Building a new pc

[4p]

After reading Ultra Extreme's guide to build a computer i decided that i myself was going to build a pc, but i need a little help I will be using it for media and gaming.

I have around £550 for a new rig.

I've been reading around, looking at this site and i have come up with these components.

Mobo: Asus A8N-SLi SE nForce4 SLi (Socket 939) PCI-Express Motherboard (MB-101-AS)

Cpu: AMD Athlon 64 3500+ Venice (Socket 939) - Retail (CP-119-AM)

Gpu: BFG 3DFuzion GeForce 7600 GT 256MB GDDR3 TV-Out/DVI (PCI-Express) - Retail (GX-025-BG)

HDD: Samsung SpinPoint P SP2504C 250GB SATA-II 8MB Cache - OEM (HD-018-SA)

Ram: I have no idea, are those ram chips with the pretty coats worth it?

Psu: what sort of psu would i need to power the above? 500w?

Thanks in advance.

Thorpy.

dod:s

Resolution: 1024x768 n 1280x1024

I was thinking about SLI, buy a sli ready mobo, buy the 7600, then in future when games demand more i could stick another 7600 in.

Conroe ey, is that intel? I always thought AMD was better.

Thanks xirokx for clearing a few things up for me.

So do you think SLI isnt worth it... In my case? I could spend more on the cpu, SLI adds quite a bit of money to the price right?
