Any thoughts on my parts list?

[Asolith]

I haven't got much experience with choosing parts for builds, so I presume there are better parts for my needs than what I've chosen. Price is very important, and I've a budget of £650. The computer will be used mainly for gaming.

NZXT Phantom PHAN-001WT WHIT6 STEEL/Plastic enthusiast ATX Full Tower Computer Case

Intel Core i5-3570 Ivy Bridge 3.4GHz LGA 1155 77W Quad-Core

ASRock Z77 Extreme 6 LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

MSI R7750-PMD2GD3 Radeon HD 7750 2GB 128-bit DDR3 PCI Express 3.0 x 16 HDCP Ready Card

Corsair Vengeance 8GB(2x4GB) 240-Pin DDR3 SDRAM DDR3 1600

Seagate Barracuda Green ST1500DL003 1.5TB

Coraair Builder Series CX600 600W ATX12V v2.3 80 PLUS BRONZE CERTIFIED Active PFC Power Supply

Optical drive: To be salvaged from on old PC

I'm fairly set on my choice of case, but I'm open to changes almost anywhere else.

Is there a difference between the i5-3570, and the 3570K other than the integrated graphics, and would it be worth the extra £10?

I've been trying to cut down on costs and I think I could save a bit more on the motherboard. A good sturdy board with the abilty to add another graphics card if I get around to it. From what I've read, a Z77 chipset is preferred.

Would the stock CPU fan be enough, considering the case itself will be very well ventillated?

Finally, will the power supply be enough to power it all? (taking into account a second graphics card)

Thanks in advance,

Adam

The graphics card you chose isn't what you should be looking at for a build of that budget. Also, you should be getting the 'k' version of the i5 (it means that you can overclock, as it has an unlocked multiplier). The hard drive you chose is the 'green' variant (slower speeds).
I'd recommend this:
