I have an DFI nf4 SLI-DR mobo, AMD 3700+ SD, 2gigs Crucial Ballistix and a single BFG 7800GTX.

1) Does my second card have to be the same one (7800?,BFG?) or can it be a higher (7900/7950?) or lower level card?

2) Is my 3700+ enough to power 2 cards?

Thanks

PS: My PSU is a PC Power & Cooling Turbo-Cool 510 SLI.
 
unit needs to be a 2nd 7800GTX, prefferably with the same amount of ram for more compatilbity, although you could run a 256 and a 512mb together but will only use 256mb. It can be from another brand and different clock speeds though.

yes, but I believe both cards will also run at the speeds of the slower card.

you would be much better off just selling the 7800 and getting a single 8800(gtx).
 
Yes one 8800 GTX is better than two 7800 in SLI but it also costs $600.
 
So I can use a bfg 8800gtx with an evga one in SLI? They don't have to be the same brands?

They have to be the same brand and the same model in order to go sli. For example, 2 bfg tech 7600gt. But there is an oc2 version of the 8800gts, you can run sli with a 8800gts (which isnt oc2) and one which is since oc2 is just saying that the graphic card is overclocked a bit by the manufacture (bfg) and still under warrenty.

Is that different then normal with the 8800s? I remember a few forcewares back they made it possible to SLI cards with different speeds and, if I recall correctly, they only needed to use the same core.

They do not have to be the same brand or specific model #, they have to be the same GPU (i.e. 8800GTS with an 8800GTX would not work, has to be 2 8800GTS's paired) I have 2 7800GTX's right now, one is an XFX and the other is an Evga with similar specs, the ram on the xfx one is 50 mhz slower than the ram on the evga, they work perfectly.
