Ok mistake on me, what is better 4870x2 or 2 9800gx2 running together?

Yesterday i posted asking if people thought if a 9800gt dual was better then one 4870x2. I was mistaken and dell sent me 2 9800 gx2 with the cross fire and was wondering if people think they would be better then running a 4870x2 ? Thanks for the help i got yesterday

Im using the new xps730x. Not sure about the mother board but its supposed to run with the crossfire they were supposed to have sent me but hey thats dell always forgetting a part or 2?

ahh so he does have an i7 system..i was wondering why they gave him the option of nvidia and ati sli/xfire....he has one of those new fangled sli and crossfire supporting boards right?...if im wrong then dell support had no idea the difference between sli and crossfire...

Two 9800GX2 is waste. Better have a single GTX295.

1 9800GX2 = 2x9800GTs OCed
1 GTX295 = 2xGTX260s OCed

2x9800GX2 is better than 1 GTX295, but it consumes far too much power and is far less efficient.

^ by just a bit, but it will consume about 1.75x the power.

With the 4870X2 you get DirectX 10.1 support!
And you don't have to deal with the horrible scaling problems from Quad SLI *cringes*

Thanks for everyones input
