Here my last year's state of the art machine is a paltry Athlon 64 with 1G RAM, 2 hard disks, the fx5700 256MB card and it has a cheapo 680 Watt PSU.
I want to expand my computers RAM and video cards but I am not sure that 350 watts will be sufficient.
Expansions: 1 gig of DDR SDRAM to 3 gigs
: 1 ATI X700 replace with ATI X1800XT or 7800 GTX( tell me which is better if you can)
You can find the norm specs of the computer here:http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1561116&Tab=2&NoMapp=0
