I normally do agree with Silencer, but I think I differ a little here. First of all the GTX295 actually is more like 2 underclocked 280s than 2 x 260s considering the chips are running 240 pipes rather than the 216 on the most recent 260s. It is capped by using the slightly slower 260 memory interface and clock speeds, but given the 55nm architecture, it can overclock to 280 speeds quite comfortably. Saying that, it seems to perform somewhere between SLIed 260s and 280s.

With regards to waiting until later in the year for new technology, this can always be a trap with IT IMO. Again you are going to be stuck being the guinea pig for untried technology which may also become obsolete fairly quickly. There are definitely jumps in tech improvements, but by and large, the "wait to upgrade" mentality can get you caught in a vicious neverending cycle.

What I like about the GTX295 is that for less $$ than 2 x 280s you get comparable performance and much less power consumption/heat production. Being the "fastest single card" offering at the moment generally means there are always going to be better value options out there, but I think the 295 still has a fairly clear niche in the market at this stage. Unless you are looking for something to pump out high quality DX10 graphics at 2560X1600, you are probably better off going with a single gpu option at this stage from a price/performance perspective.
