GPU Upgrade

Here is the case.
I recently bought a new system,including:

-8 GB RAM
- A GTX 660
- Intel i5-3570 (4x3,4Ghz)

So my question is,what GPU should i buy next?Crysis 3 runs on stable 40-50 fps on High.25-35 on Very High.
But im thinking about buying a second GTX 660.
Or should i go for a GTX 680 or 690?

And what about the heat?I dont have a watercooling system

But a 690 costs around 900 euros here.Lets say i'll sell my card for 100,i'd have 350 euros in total.Any GPUs for that price?

i hear there's a line of 700 cards coming form nvidia so wait a little bit and pick one of them up perhaps or go with two 660ti's i used to run that without watercooling and it was at a good stable heat and i had a EVGA stock cooler on those bad boys right up until i got my 690 for a trade of the 2 660ti's and YuGioH card deck ya a card deck

Go for the 780!

Save your money and buy one of those!
I'm thinking of buying 3x780 running SLI and watercooling them!

If it's a standard 660, I'd say sell it and invest in maybe a 680/690.
If it's a 660 Ti, I'd go SLi 2 x 660 Ti's

They'd be roughly the same price. From what I've heard, 660 Ti's in SLI perform up to 50% better than a Single 680.

2 660 sli

id wait a little bit till nvidia brings the 700's

Oke,thank you =)
