6100 Integrated?

[NeXuS1]

Im getting a new comp my parents want
to buy me a pre-built one from gateway
it has really nice specs i cant complain

AMD Athlonâ„¢ 64 4200+
2048MB DDR (4 x 512MB), 400Mhz, dual channel
320GB (7200 RPM, 2MB cache)

Now it has this as the GPU
NVIDIA® GeForce® 6100 GPU
up to 128MB of shared video memory
PCI-Express (PCI-E x16) slot available
Its integrated right when they buy it
im gonna get a Nvdia 7800GT or
if the new X1900 doesent seem so expensive ill go with that
its shared right so it takes some RAM right and what PSU do you estimate it will have cause i cant find whats the Watt supply?

This total guess but I think it'd probably have a 450W PSU total guess though. The integrated one doesn't use the RAM I think but I don't really know but the 128mb is the ram for the gpu so I would say it wouldn't. Will be nice system with the new GPU =D.
