i have used x1800xt-512MB on this.... so take your decision...
here is the source -
The truth about graphics power requirments - Graphic Hardware - Forums - www.atomicmpc.com.au
let me be frank with you. if you were running any card like x1800xt-512mb i had then i might asked you to think twice coz it was just reaching to its limit.
but with 6800GT there is no problem dear..
thebanik - sorry man. i have already reduced too much. and both products are heavy so shipping will cost extra again.... so please think again..
