I really Want to do a cross fire or sli .I know a single gpu is the best way to go but I want to do a multiple gpu system because of watercooling
 
Solution
You can still watercool a single card system. You don't need multiple cards to watercool.

If you do insist on going dual cards, though, your budget is the main limit. If you just want dual cards for the sake of having dual cards, get entry-level cards that allow for SLI/Crossfire, like the 270X or the 960. But I would still recommend getting a single card system, since there would be plenty of disadvantages to a system like this.

Full size waterblocks are, but you can get universal ones that fit practically any GPU. They don't look as flashy, but they work.

Care to mention the board make/model? Specs? No sense recommending more than the system can support... or your budget.

Yeah, that's one of the reasons people don't recommend doing it.

Low end cards are indeed not the best. But if you insist on going multi-card just for the sake of going multi-card, it's the cheaper way.

I still would recommend just getting one card. You can still do watercooling on it, and you are even able to get the fancier waterblocks that we mentioned earlier. It's overall a better idea, unless you need more power than what a single card can do.

That board will do CF or SLI nicely. While a single card is usually better, it is fun to experiment with dual cards too. The single GTX 980 would be the way to go, but a couple GTX 960s would probably give you greater FPS at roughly the same price.
Or a GTX 970 now with a 2nd one when finances allow.

Any i5 or i7. But I thought you were wanting opinions on dual or single cards.

If I were building a system build like yours, I would recommend you get a single GPU, just because it'll work better than a CrossFire or SLI setup of similar cost. I've heard numerous complaints before that people have gotten two cheaper GPU's, put them in CrossFire or SLI and regretted it afterward. Often, you'll see a noticeable drop in framerate if you use two cards that are each 1/2 as powerful as 1 card.

However, you may be asking yourself, "if having two GPU's creates lag as opposed to one more powerful GPU, then why are there high-end cards that are dual GPU's?" The fact is that, with CrossFire and SLI, you have only a relatively small bus going from one GPU to the other, which tends to bottleneck the communication between the two. Beyond a certain level of GPU power, though there is so much parallel traffic going across the GPU that having two dies is actually an advantage, in spite of the bottleneck on the CrossFire/SLI bridge. This is why you see high-end dual GPU's at the upper end of the market.

Also, if you are looking for CrossFire or SLI, I would say that a GeForce GTX 970 or a Radeon R9 290 would be the minimums in their respective classes; however, before you do CrossFire/SLI I would recommend you consider a dual GPU solution such as the GeForce GTX TITAN Z (which is all right) or the Radeon R9 295X2 (which is better than the TITAN Z and currently holds the prize for the fastest desktop GPU in the world).
