AMD system, whats wrong?

Heres a new system that I'll be putting together soon, no serious gaming; mainly just video and photo editing (CS2 and Sony Vegas etc), running at 1680x1050 on a 22" lcd.................any problems or cheaper options?

Gigabyte GA-MA78GM-S2H AMD 780G Micro-ATX (Socket AM2) PCI-Express DDR2 Motherboard £59.99 (£68.99)

Corsair VX 450W ATX PSU £48.29

AMD Athlon 64 X2 Dual Core 4200+ 2.20GHz (Socket AM2) - OEM £24.99 (£28.74)

Western Digital Caviar Blue 640GB SATA-II 16MB Cache - OEM £40.24

Corsair 2GB DDR2 XMS2-6400C5 TwinX (2x1GB) £18.99 (£21.84)

Gainward BLISS GeForce 8600 GT 256MB GDDR3 HDTV/DVI/HDMI (PCI-Express) £28.74

Akasa AK-191-SM Smoke Ultra Quiet 120mm Fan £5.74

Well, I can tell you now, you'll probably want something faster than the 4200+, I would probably look at least at a 5000+ if going AMD, also see about geting the retail version as it would come with a cooling fan.

I've been seeing manufactured PCs for sale with the AMD 4400+ for around the $300 range these days. It's an outdated processor by the most current standards. For simple email & internet, it's fine.

If you want to do a lot of video editing, I'd go faster.
