This is obviously a lot better than what the OP originally had, but I would make a few changes:
- CPU: For a pure gaming rig, I see no reason to get the 3770K over the
3570K. HT only gets you a very minimal improvement in gaming performance.
- Mobo: Obviously a very nice board, but given my comments above, I don't really see the point in getting a CFX capable board for 1080p. The
Z77 Pro3 is a good fit IMHO.
- RAM: Good deal, but I'm not convinced of it's utility for a gaming machine.
8GB is enough for gaming. Hell, most games aren't even 64-bit.
- HDD : Reasonable value with the promo
- SSD : Good
- ODD : Good if the OP wants Blu-Ray
- PSU : Good unit for a good price, but since CFX is not really a good upgrade path, this
Silencer Mk III 600W for $57 AR AP is more than sufficient.
- GPU: Surprisingly not bad since it's sub $500
- HSF: Overkill for a beginner overclocker. The
Scythe Mugen 3 performs extremely well and is less of a hassle because you don't have to mount it to the case.
- OS: Good
- Case: Kind of overpriced, but I guess personal preference plays a big role here
- Sound card: Fine card, but the Companion 5's have their own USB sound card, and completely lack an analog input as far as I can tell. So the Xonar would be of limited utility.
