Intend to build a gaming PC. Is this OK?

Will be building a new PC in the late November, early December. Here are the things I have picked out:

Motherboard:
Intel Desktop Board DP67BA

Ram:
G.Skill RipjawsX 2x4GB 1333MHz

CPU:
Intel Core i5-2500K

Video Card:
ATI HD 4850 (already have it, so I don't think I'll be changing the video card)

Case:
Thermaltake V9 BlacX Edition with Docking Station

Hard drive:
Kingston SSD SATA2.5" 64GB/SV100S2/64G (for OS)
(Already have a HDD for games and such)

PSU:
Corsair TX V2 750W

Also have a 16x DVD RW optical drive

I am not too sure of the motherboard, if it is good or not, but I think it'll work. Suggestions and tips are welcome

I would go with an Asus board or Gigabyte. The rest looks good to me.

Well I don't have a certain budget, just a reasonable price. I don't need the very max high end gaming PC, just a good one that will last for years. I'd say roughly 800-900 dollars.

I have a samsung syncmaster 213t, which is 1600x1200.

The games will be Skyrim, BF3, LA Noir, ARMA 2 and such. Pretty much most of recent good games.

I will start using SolidWorks for 3D design in the next year, but other than that it will mostly be used for gaming.

I guess I could jump from 750W to 650W, for example CORSAIR TX 650W, but the value difference is about 17 dollars, which is not too much for extra 100W. But then again do I really need that extra 100W.
