Fine tuning new PC spec

[globule]

Hey guys, was wondering if i could get some opinions and suggestions with my new build (compatability and quality etc.)

CPU
AMD Athlon 64 X2 Dual Core 4800+ (Socket 939) - Retail (ADA4800CDBOX) (CP-129-AM)

Motherboard
Asus A8N-SLi Premium nForce4 SLi (Socket 939) PCI-Express Motherboard (MB-111-AS)

RAM
Corsair 2GB DDR XMS3500LL Pro TwinX (2x1GB) CAS2 (MY-093-CS)

GFX
PowerColor ATI Radeon X1900 XT-X 512MB GDDR3 AVIVO TV-Out/Dual DVI (PCI-Express) - Retail (GX-059-PC)

However im undecided about the PSU. I was looking at the Enermax Liberty range, they look good but wasnt sure what wattage is needed for the above gubbins.

Also for the heatsink i read that the ThermalRight SI-120 (Socket 754/939/478) Heatsink (HS-023-TR) is good. Does it need a fan bought seperatly? If so any suggestions?

I've already got the other stuff so the above is all i need now, but im a bit nervous spending all that money on it without getting the opinions of people who know more than me If anyone can put my mind at ease and help with the finishing touches id be greatfull!

Thanks.

I wouldn't bother with that CPU, drop it down to a 4400+, it's only 200 MHz slower and you save a lot of notes

Should be a very nice rig!

Enermax Liberty 500W ELT500AWT ATX2.2 Modular SLI Compliant PSU (CA-025-EN)
Price: £63.95 (£75.14 Including VAT at 17.5%)
This should be fine.

You could save a fair bit of money by going to the 4400+ (or Opteron 170 if you preferred), and the X1900XT rather than X1900XTX, and the difference in performance would be fairly negligable, and if you overclock a bit, nonexistent.

You don't need a SLI mobo either. Save money either on the Asus Crossfire or the similarly priced non-SLI NF4 Asus board.
