DUAL GPU Cards

What is your question?

Do you want to know if you should use two GPUs?
Is the power supply enough? You would have to tell us what kind of card you want to use in SLI/Xfire.

Not sure what you are asking for.

something resembling the gtx 590, gtx 690 or gtx 560 ti 2win

getting a last gen dual gpu card is stupid. you can get a current gen high end card and it will perform similarly with nowhere near the power draw or heat output.

a 690 would be a great card if you really need the power, but right now a single 680 or 7970 is more than enough for any game.

metro 2033 is the most annoying game i have

I haven';t played it recently, but i was able to max it on my 580 with about 40-50 frames. so im sure my 680 will get a solid 680 overclocked.

either way, a 590 or 5602win is a bad idea. grab a 7970 or 680. if you want a dual gpu card for shits and giggles, get a 690. at least then you'll have more power to show for it.

i saw the nvidia page on the gtx 690 and metro 2033 still comes up sluggish

do you actually intend to spend that much time playing metro though? it was an average game two years ago.

you just don't seem to be very open to advice atm, so if you really want to spend huge amounts of cash on something you most likely will not utilize, that's your choice. But you came here asking opinions and i'm sure most will share mine.

don't get me wrong, I will probably be getting a second 680 on the future. but i tend to enjoy spending large amounts of cash on my pc. the very fact you are here asking the question leads me to believe you are more interested in performance and cost. in which case, a 690 is not going to offer a significant advantage over a 680. especially not a 500 dollar advantage.

i actually like the game, that and bf3

Those two games are GPU dependent, but as to what card to get depends on the resolution you plan to run the games at. If your running 1280x720, you could get away with a plain 560Ti and still run those at near maximum, if not maximum quality. On the other hand, if your running eyefinity at 2560*1440 with 3 monitors, you will probably want a GTX 690 to reach playable framerates at max, or near max quality. As far as going with older dual GPU cards, it's not worth at. As of today, a GTX 590 will cost you somewhere between $600 and $800USD, while a GTX 680 costs around $500-$600. While the cost savings is nice, it's boosted by the fact that the GTX 680 with a single GPU not only costs less and takes less power, but is faster in all mentioned games, even when running Eyefinity.

I only have a single screen but higher res 2560x1600 at the moment until better screens surface

Then skip the last generation dual-cpu cards since they are outperformed and outclassed by current generation cards.

For the games you like playing and at that resolution the best options are for you to get a 680 or 7970, if you have the budget for the 690 go for it , or go 680 SLI

I am thinking of waiting a bit for the price of the GTX 690 to level off a bit

Best choice, or wait for the 680 prices to drop when the 780 is released.

Maxwell is still a ways off I believe, maybe 18-24 months
TSMC is having problems with 28 nm let alone 20 nm or smaller
