4830 CF in a x16 and x4 slot?

[psycoshot]

Hey,

I have this mobo
http://www.newegg.ca/Product/Product.aspx?Item=N82E16813128382&Tpk=UD3H

and I want to add a second 4830. I was wondering, what kind of performance loss will I get because it will be in a x16 slot but running at x4 (so i'll have two 4830, one running at x16 and one at x4)

Is it still worth the upgrade? (1900x1200 resolution)

Here's some food for thought
I only have an x4 slot availbable on my intel backup rig (x16 slot is broken) when sitting in there, my 9600GT get's bottlenecked by the bandwidth of the x4 slot. seeing how a 4830 is much more powerful, it will be heavily bottlenecked by the x4 slot on the p35's

okie.

maybe ill give this mobo to my dad, get a better one for crossfire and then get a 4830?

Is the antec 400W enough to CF 2 4830?

I would recommend getting a bigger poweresupply
what resolution are you playing at? I would recommend you jsut sell the 4830 and save up for a 4870 or 90. That would be a better idea than crossfirex 4830's

1900x1200 (soon i'll upgrade to that)

I'm still trying to decide. maybe ill just wait till the 5xxx
