What mobo?

[Skulhead = hacked.]

I am planning to upgrade my computer with a:
Geforce gtx 660
Intel i5 3570

Which mobo works good with this? And how much W should I need?

[Nachos]

When I wrote "best mobo for i" google suggested "best mobo for i5 3570k" as the first thing, try googling that yourself, that is probably what most people replying to this thread will do for you.
Well, I'll answer you anyway: Gigabyte Z77 GA-Z77X-UD3H ($400)

Motherboards doesn't mean that much, so you don't need to spend $400 on one. You can get some great ones for $200.

As for how many watts power supply, i assume, you need, 500-750 would be enough.

So it will cost something like $200?

What do you mean? You can get a fine mobo for $200.

I don't know about the power supply.

Not sure about the mobo but a good quality 600W PSU will cost around £50-60 (British pounds)

You don't need a $200 mobo for that. Go with the ASRock Z77 Extreme4 or the MSI Z77A-GD55.
Newegg.com - ASRock Z77 Extreme4 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
Newegg.com - MSI Z77A-GD55 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard with UEFI BIOS

A 600w will be fine for that build
Newegg.com - Antec HCG M Series HCG-620M 620W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply

I will recommend you don't get a GTX 660. Go with the 7870.

I hope that's the 3570k you are talking about?

You can even take asus p8z77-m and you are good to go.
Remember , if you take a Z77 board that means you have plans to do overclocking in the future, if not i would suggest you to buy even less expensive ones.

How can I be sure of this? Is there like a site to calculate it?

...... use your brains?

Check the size of each products, draw a diagram in your brain to picture it.

Mobo should cost around $100 bucks. It's fairly easy to pick one, just make sure it fits the processor and has pci express gpu slots and then its preference.

Close please, found out that my tower doesn't support atx.
