Is this worth the 520 ?

If I can get all these part and build my self a computer for about £520 would it be worth it or would I be better of just buying a computer these are all the parts I'm planning on getting buying if its worth it:

Asus Commando Socket 775 P965 DDR2 3X PCI-E Vista Ready Motherboard
Intel Core 2 Duo E6320
OCZ 2GB (2 x 1GB) 800Mhz PC6400 Gold Memory
XFX 8800GTS 320MB, PCI-E Graphics Card
Seagate 250GB IDE 7200rpm 16MB Hard Disk Drive
NEC AD-7170A-0B Multiwriter Black 18x DVD±RW
Antec NSK6000 Super Midi Black/Silver Tower Case
Ezcool Super Silent 700W Tornado Gaming Powersupply

P.S I got this from using a guide I found on Games radar heres the link if you would also like to built this computer if you think it is worth it:

How many dollars per pound again?

Also, I wouldnt get that motherboard or that GPU unless you are getting them at a huge discount. Get a mobo with a p35 chipset and an 8800GT or an HD3870. Also, that PSU is overkill. A quality 500watt PSU is fine.

Hers the prices for each thing is it still not worth it by the way its in british pounds (£) :
