i am not Nvidia and Intel fanboyLooks like OP is a Nvidia and Intel fanboy, or a person who's bombed by Nvidia and Intel "goodness" by retailers at his place..
@OP, I suggest you to go with Cilus.
Just my worth of advice to you.
Cilus i respect your opinion commpletelyI am not getting one thing, if you want Multi GPU support, why not AMD 990FX platform. It offers far better quality than any of the sub 10K Z77 motherboards. Because of your changing needs, now you're pairing a Non-K processor with a Z77 Motherboard which is idiotic if you ask me, just spending 4K for one PCI-E X16 slot.
on the other hand, if you go with a FX-8350 + Gigabyte GA-990FX-UD3 combo, you will get all the options you are looking:
Good build quality, lots of expansion slots, both SLI and Crossfire support @ X16-X16 speed and very good overclocking potential. Just consider the value it offers as a whole sytem, not just CPU performance. In real life, this is a far better solution and I am holding strong in my position.
Don't get me wrong here, although I love AMD processors, I am not at all any AMD fanboy. But just for getting Intel, the way you are mixing up things: paring a Non-K processor with Z77 motherboard, not able to accommodate a CPU cooler, spending 4.5K extra for a single X16 slot..... I don't think but know you are really going in wrong direction.

We have a lot to talk about in regard to multi-GPU performance and gameplay experience in Far Cry 3. The first thing to keep in mind is that raw faster framerates doesn't always mean a better gameplay experience. There are other factors involved that framerate cannot measure. We experience these other variables as we play the game, and subjectively explain the experience to you.
In the table and graph here, you will find that the AMD Radeon HD 7970 GHz Edition CrossFire setup had the highest framerates, beating GTX 680 SLI in raw framerate. The minimum FPS is higher, 42 vs. 37, the maximum is higher 62 vs. 53, and the average is 14.5% higher at 51.2 versus 44.7 FPS. This is at the same playable settings of 2560x1600 with 4X MSAA, Enhanced Alpha to Coverage, HDAO and Ultra in-game settings.
While the framerates are faster under CrossFire, the gameplay experience is noticeably different between GTX 680 SLI and HD 7970 GHz Edition CF in Far Cry 3. We experienced a horrible amount of stuttering under CrossFire. It was as if the game was pausing every few frames, making the game choppy, and the performance inconsistent. The gameplay experience was close to awful using CrossFire.
We did find a way to fix it though, but the catch is you have to enable the "2 Frames" VSYNC option in the graphics settings. What this will do is cap the refresh rate to half of what your display is. In this case, our display is 60hz, so VSYNC x2 sets the FPS to a constant 30 FPS. In doing so, this completely removed the stuttering and choppiness under CrossFire. We were then able to have a smooth experience at any resolution, up to 2560x1600 with 4X MSAA. Therefore, you are not able to achieve the "full potential" with CrossFire, and experience a smooth gameplay experience. You have to cap your framerate well below the average FPS, in order to make CrossFire as smooth as SLI.
On the other hand, SLI had no such issues. We were able to keep VSYNC turned off at 2560x1600 with 4X MSAA and still experience smooth consistent gameplay performance. There was no choppiness and no stuttering with SLI. So the difference here is that we were able to actually play the game at higher framerates with SLI, whereas with CrossFire we had to cap the FPS to 30 FPS. The difference was extremely noticeable.
Cilus i respect your opinion commpletely
and i am not pairing i5 3470 with z77 motherboard but i5 3570k with z77 motherboard i decided to leave operating system and buy apc600va ups
the reason why i am going for gtx660 sli is becuse it gives better performance than a gtx680
TAKE A LOOK AT THIS CONFIG :
Intel i5 3570k 14300
Asrock Z77 Extreme4 10000
Cooler Master Hyper 212 Evo 2000
Corsair Vengance 2 X 4gb 3000
Western Digital Caviar Black 1Tb 6100
Gigabyte GTX660 OC 14700
BenQ GL2250HM 8300
Corsair GS600 4400
NZXT Source 210 Elite 2500
ASUS DRW-24B3ST SATA 1000
APC 600VA 2300
Logitech k200 400
Logitech g400 1500
Razer Goliuthas 500
TOTAL 71000
i have read a lot of threads at tdf and i have learned that buying a non k processor will not be future proof..Gigabyte Z77X D3H it is a better board of the two. You can go for it. Since you have come this far spend Rs 700/1000 (aprx) more and get a 3570K processor over a 3570/3470 with the Z chipset based board and GTX 660 now and one later as you wanted.
Now the other solution is to stick with the non K processor that is the 3470/3550/3570 and get a good Gigabyte H77 board with a powerfull single GPU like an HD7950 or a HD7870. You can put the saved Rs 4000 on the motherboard for the better GPU.
