i would buy the 7800 gt 256 mb you will see more performance out of that one card than than 2 of those other cards

ok so get the 7800, very good point i could get 2 7800 later on wen ive got more money. Wot kind of power does a 7800 need, ive got 400W

Wot kind of power does a 7800 need

It draws around ~100-110 Watts of power.

ive got 400W

Should be ok but it's hard to say not knowing your psu's specifications.

cheers mate, well if ive read this right only the 12v rail really matters
It say on my psu
+12v = 17A
that aint really good enough is it

The GF7800GTX requires a 450W PSU and the +12V rail should be atleast 25A these days. Preferrably more like 30A.

not quite true.. with my mobo came the manual.. wich says. my SLI mobo. with 2 pci card, 2x 6800ULTRA all usb ports connected. so under full load. the 12V rail must have 25A minimum.
and the 6800ULRA and GT draw much more power that a 7800GTX (i thought it was about 200W each)

 

[Cromewell]

no the 7800GTX draws ~3% more power than the 6800Ultra. So while being way more efficient the 7800GTX does draw more power. The 6800Ultra/GT doesn't draw 200W, when you see those power load graphs it is almost always the draw of the entire system thats why they show the idle and load figures.
