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.
