First Build (i5, GTX 460)

Hello, I'm planning to purchase a new computer soon and have gathered these parts. I'm not a total noob, but I just want to make sure everything is a-okay and if there's anything I can fix.
I tried to keep everything around/under ~1k. Also, I'll mainly be using this computer for Starcraft 2, WoW, and then just school work. I also want it to be i5 powered. If there's anything I can change to make it cheaper, that would be great.

CPU: i5 750

Mobo: Gigabyte GA-P55

RAM: G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600

GPU: EVGA Nvidia GTX 460

Power Supply: Corsair 750W

HD: WD 1TB 7200 RPM HDD

OS: Windows 7 Home Premium

DVD/CD Burner: ASUS

Case: Xclio windtunnel

Approx. Total = $1,100

For the case, I just chose some random good looking case. It's probably overkill, so if there's anything cheaper with good quality, I'm up for it.

Thanks

^ Why do you need a 750W PSU ?? Planning for SLI ?? SLI is not supported by the board you have chosen...

Sounds much better gkay, and yeah I have no idea when it comes to today's graphics cards/ what's the best etc. And I don't plan on doing SLI/Crossfire, I just thought those were optional and you don't have to use them. Can you suggest exactly what GPU I should get?

I'll most likely be playing on a 22"-24" screen, and sometimes my 32" HDTV.

Thanks. Money saved and problem solved.

You probably don't need an i5 if you're playing Wow and doing schoolwork... an i3 or even an intel quad core would be good enough
