which is better

Which works better say for example two gtx 290 in sli or single card with two 290 chips

Sorry, m8 - there is no such card as the gtx 290. The current nvidia GT200 based line is: 260, 275, 285 and 295.

The GTX 295 is the only one which is a single card with two chips. It performs approximately as well as two GTX 260s in SLI. If you went for two GTX 275s or GTX 285s in SLI then you would get better performance. However, when you put two cards in SLI the power usage is more than two GPUs on one card.

However, if you are planning on getting a new card now - I suggest against going for Nvidea and instead try to get your hands on the elusive ATI HD 5850.

Actually the 295 is 2 x 275 gpus on the same card. 480 SP's as opposed to 432 on 2 x 260's.

Aye, it is - but the cores are downclocked when compared to a GTX 275 - so in benchmarks it performs very similarly to 2 x GTX 260s in SLI, while 2 x GTX 275 is a good chunk faster than a GTX 295.
 
Sorry my mistake. I am talking in general terms. What I am saying is say you have a graphics card named super graphics 10 and on the card is graphics chip named super 10. Which in general terms would tend to give you the best performance. Two super graphics cards in SLI or one single card with two super 10 grahics chips on the board. I am also assuming two the chips on the single card have the same specs as the chip on the SLI cards.

I hope I am explaining my properly lol
