which system is better

can you guys help me i am looking at two systems can you tell me if there is much difference between these two systems and any changes you might make for roughly the same money or bit more?

the two systems i am looking at at the moment are

AMD athalon 64 x2 dual core 6000+socket AM2 3Ghz 1MB
Gigabyte M57Sli-S4 Skam2 ddr2 raid, g-lan
2 of RAM 1GB 240PINS DDR2, 667Mhz
Asus 256MB radeon 2400pro PCI express or 8600GT ($130 more)
LG 20x dual layer DVD-RW oem black
seagate 500GB SATA 7200rpm 32MB cache
Superflower SF706BK Leather Black Panel (450w)

or

INTEL CORE 2 DUOE8200
ASUS P5KC P35 1333FSB INTEL
2 OF KINGSTON 1024MB DDR-2 667MHZ
WESTERN DIGITAL 500GB SATA 2
ATX-8033L-C43 USB
LG 18X-DL BLACK DVR/RW SATA

THE SECOND UNIT IS $200 AUS DOLLARS DEARER BUT FROM A DIFFERENT CLASS OF SHOP TO THE FIRST

 

what graphics card does the 2nd one have?

if it has integrated graphics, i'd say that the 1st one is better

 

the second one is built in but i said i didnt mind if it was built in or not so long as i had the option to fit one in the future.
