Any suggestions for new card in older motherboard?

Hi everyone!
I have been out of the game for a while and want to get back in and start to play some the new nextgen games (Shadows of Mordor, WatchDogs, Alien Isolation, etc)
However I am currently in a pickle as I am not too sure what I want to get. Currently my system is about 6 years old but works great, the only thing I need to replace would be the video card. Since my current motherboard does not support PCI Express 3.0 (only 2.0) I dont what to get. I have read that if I were to get a PCI Express 3.0 video card it would still work on my current 2.0 slot. Is this correct?

Motherboard: EVGA X58 SLI LE (http://www.evga.com/articles/00481/)
CPU: Intel i7 920
Current Card: ASUS EAH4870

I want to turn my system into a watercooled one in the next month or two and would prefer a card where I can buy a full cover waterblock for it.
Currently looking at the EVGA SuperClocked 02G-P4-2662-RX GeForce GTX 660 2GB which is $150 for a refurb model (would prefer an EVGA card).
Any other suggestions?
Price range around $200 for now

Thanks!

What resolution are you gaming at?

Right now at 1920x1080

GTX 760 for $200

Thanks for the recommendation AMTINSIDE.
I tried to look up waterblocks for the EVGA GTX 760 but cant seem to find any. Do you know of anywhere I could get some?

Thanks!

IIRC that GPU should fit with any reference water block for the 670/760.
Don't count on that though, I haven't messed with the 760 stuff in a while.

That said, the 760 runs cool enough that I wouldn't worry about watercooling it.
And the block will cost half of what the GPU does.

If you're planning for a $200 GPU and $100 block, why not just buy a GTX 970?

you do make a valid point
I will need to rethink this haha

Just to hammer the point home, here's a comparison of the 760 to the 970:

Thanks ATMINSIDE!

270/270x and 280/280x can all be found now for near 200 dollars depending on where you live, i ran a 270x for almost 7 months with a i7 920 first gen and a old pci 2 mobo. Now the 280/x cards are closer to 200 usd then 300 id probably go for one of them.

A 970 will mop the floor with any of those cards, notice the OP's change of direction.
