Ordered parts for my first PC!

Happy to report that I've just ordered all the parts from NewEgg.com for my new PC, which will be the first PC that I'm building myself.

It's a little bit overwhelming, and I probably made some mistakes with being cost effective, but I'm pretty excited. Here's everything that I ordered:

OS: Windows 7 Home Premium 64-bit
CPU: i5-750
GPU: ATI Radeon HD 4890 1GB
RAM: 4GB 1333MHz
PSU: Antec 750w (for near-future CrossFire upgrade)
Motherboard: ASUS P7P55D PRO LGA 1156
Case: Cooler Master RC-690
HDD: Seagate 1TB
DVD: Sony Optiarc 24x DVD/CD
LCD: Samsung 24" 1920x1200 HD
Fans: 2x extra 120mm Scythe case fans

Opinions? How strong is my PC going to be?

Also, I'm a complete noob when it comes to PC assembly.
If anyone wants to offer advice or links to guides, their experiences with any of the parts I have, etc., I would really appreciate it.
I don't even currently own a desktop PC that I can reference during this process.

You could have done better. It'll run everything at max from what I can tell though.

Instead of the 4890 you could've gotten the 5770. For the case you could've taken the HAF922/932 instead of the RC 690.

People I talked to recommended 4890 over 5770, actually. 5850/5870 would have been ideal but they're impossible to find right now.

I don't know much about cases... but I heard good things about RC-690 so I went for it.

The 4890 may be faster now, but future drivers can still squeeze out a couple of more %'s of perfomance.
The 5770 also uses less power and has DX11.

You heard good things about the RC-690, but the HAF932 is the god of PC cases now... Cheap, cools well and apperantly great cable management.

I didn't wanna bother with pirating.
