I am trying to build a new PC mostly gaming

at the moment i have
CPU :Intel 3rd Generation Core i5-3570K CPU (4 x 3.40GHz, Ivy Bridge, Socket 1155, 6Mb L3 Cache, Intel Turbo Boost Technology 2.0)
Mobo:AsRock Z77 Extreme4 Motherboard (Socket 1155, Intel Z77, Up to 32GB DDR3, ATX, 2 x SATA3 6.0 Gb/s, Supports NVIDIA SLI and AMD CrossFireX, Premium Gold Caps)
Ram:2xCorsair CMZ4GX3M1A1600C9B 4GB 1600MHz CL9 DDR3 Vengeance Blu Memory

and For graphics i am thinking:
EVGA Nvidia GTX 660 SC 3Gb PCI-E

For PSu:Corsair Builder Series CXM 750W Modular 80 PLUS Bronze Certified ATX/EPS PSU

the problem is that i am thinking to do Sli in the future will the psu be able to support it or i should get an 850w one?any suggestions about hard drives and the still missing parts are welcomed.

750w will be fine for SLI, but I highly recommend you don't put two 660s in SLI. First of all, buying a 3GB 660 is pointless - it can't even make good use of that much vram under gaming load. Second, it makes WAY more sense to go with a single, more powerful card - there will be fewer heat and space constraints, no microstuttering, and it'll give you solid performance in EVERY game, not just the ones that have good SLI support.

Buy a single GTX 670 and a 550w power supply, and you'll be able to max out pretty much everything at 1080p.

As for other parts, go with a 1TB Western Digital Blue and a 120GB Samsung 840 SSD.

Solid gaming build with upgrade potential.

Here's an XFX modular power supply made by Seasonic ready for SLI:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817207022

That 650W PSU has enough power for 2 GTX 660s and the rest of your system and then some.

A decent air cooler is a Cooler Master Hyper 212:

I'd also beef up the RAM to an 8GB kit:

Just need to know how much more you have to spend?

The reason that i was thinking about the SLi is that the Gtx670 are around 80€ more expensive than the 660...so i was thinking about going with one 660 and then buying another for netter performance...

Sorry, for some reason this thread didn't get subbed - I'll try to answer as many questions as I can:

1) If the 670 is only 80€ more expensive than the 660 (not the 660ti), then it's a freaking steal, and you should buy it as soon as you can./

2) While two 660w could outperform a 670, they would only do so in games that have good driver support - that's not that many of them.

There's great driver support for SLI with just about every game.

What is the source of info that would lead you to believe there isn't?

This review can give you an idea of the performance you should expect for some games with two 660s in SLI:
http://www.tomshardware.com/reviews/geforce-gtx-660-geforce-gtx-650-benchmark,3297-14.html

But like many reviews, it doesn't include comparisons to many cards by which it would make sense to include (ie 670) so you have to go to a 670 review to get the 670 info.

It's all about the budget. If you can get a 660 now and pick another one up later, this makes sense. Get the best single GPU solution you can now (within your budget) and pick up another when you can.

SLI works great and Nvidia does a spectacular job of supporting its multi-gpu customers.

I would get something more along the lines of a 750 or 800w if you're looking to power two cards in the future.

Take a look on pcpartpicker to find one within your budget: search for modular or semi modular, 80+ certified to 80+ gold certified, and 700-899w. Then search by price going up until you find a reliable brand within your budget.
