Building PC help

[jet5568]

Hello.

I have questions about a computer I would like to build. Firstly, here are the specs:

CPU: Intel Core i5-2500K 3.3GHz Quad-Core Processor

Motherboard: Asus P8Z68-V LX ATX LGA1155 Motherboard

Memory: G.Skill Ripjaws Series 8GB (2 x 4GB) DDR3-1600 Memory

Hard Drive: Seagate Barracuda 500GB 3.5" 7200RPM Internal Hard Drive

Video Card: Gigabyte GeForce GTX 680 2GB Video Card

Case: Cooler Master HAF 912 ATX Mid Tower Case

Power Supply: OCZ 750W ATX12V Power Supply

Optical Drive: LG GH24NS70 OEM DVD/CD Writer

Monitor: ViewSonic VX2753mh-LED 27.0" Monitor

Operating System: Microsoft Windows 7 Home Premium SP1 (64-bit)


My questions are:

Will 750W of power be enough for the computer?

Will all the specifications work together?

Will this computer be powerful enough to max out games at 1920x1080 and ultra settings like Battlefield 3, Crisis 2, Skyrim and The Sims 3?

Should I get an i7 CPU or just stay with the i5? I heard the only difference is that the i7 has hyper threading - does anyone agree?

I would really appreciate anyones help.

Sorry but realised I forgot a question.

Should I put any cooling fans in the computer as I live in a hot area? !)

Yes add fans, I would buy two 200. swap the front 120 with the 200 and put the 120 in as a side. then put the other 200 as the top fan. Total 4 fans.

The i7 is clocked slighly higher, has a bit more cache, and hyperthreading. Thats the only difference with the i5's.

750w is fine for a single gpu system as well as many sli/crossfire setups.

You should be able to run just about any game on ultra.

Also, I would like to ask two more questions.

Should I get an i7 instead of an i5 as I was wondering if an i7 would make a big enough difference in performance for gaming?

If I get an i7 will I have to also upgrade my power supply or is 750W enough?

Thanks for all your help.
