i bought my 730 h2c with dual 3870HD x2 cards. i have been trying to get them to change, but now on my second machine, 2 failed engineer visits, the last one today, its actually got worse. the machine now runs slower, according to 3dmark06, was at 19000+, now its 16000+, with one graphic card turning it self on and off. and the engineer managed to scratch my lovely 730 chassis down one side on some screws. it took him 3 hours and he left me for another call, even worse than before he called. NOT IMPRESSED.

so dell are sending my a brand new 730 h2c machine, again. i 've asked for nvidia cards. the supervisor said he wants to do some research, as last week, a senior tech supervisor told me there where problems with the 730 and ATI cards and they may have to give me nvidia cards. i can almost guarantee they will not be the 9800GX2, but i will try.

My father has one society and dell let them to buy his equips by renting (it´s a perfect way to pay cost machines ) i get the xps two months ago 

So I only have to call them and say i want to change my ati cards for dual 9800GX2 and they will hear me ? that´s my question... can I say that I´m not satisfacted with them or better I say that they don´t work at 100 % ??

sorry for my english once again and thank u for your answers

from my experience with Dell is, that they will say no. i think you said you rent the machines, so its on a contract. it depends upon the contract terms, usually to change it, you have to terminate the contract early, so there may be penalties. if you are having no problems, why would dell change, thats what they will say. you can only try and ask.

there is an issue with ATI's on the new 730, the dell tech have told me that and even some of the others who post here have identified that from ATI themselves. the engineer which came out, sid the motherboard was a new revision, fixing some the these problems. it made them worse for me. the ati should work ok in the 730, but as the motherboard is Nvidia, the Nvidia cards will work better (I hope). i think the problems i have had and am having show that. i'm on my second machine now, and second motherboard and second lot of ati graphic cards, the problem continues. something is not right with this setup.
