In generally, it's nt that great. That board is super expensive and doesn't give you a whole lot. You'd be better off with an Asus P7P55D-E Pro for $100 less.
BluRay is a waste of money unless all the following conditions are true. 1.) You own a lot of BR movies/discs. 2.) You watch them exclusively on your current PC OR your PC is hooked up to your TV 3.) You don't own a BR player or PS3 and 4.) You cannot find a player for under $100.
If this is a gaming build, it's very bad. You don't need 8 GB of RAM for gaming. nVidia is a horrible choice for GPUs right now. The cards just can't compete with ATI's 5xxx sereis cards.
If it's for gaming (or even if its not), take all of the savings above (I estimate about $300) and pick up an HD 5870 as the GPU.
If this is for gaming, here's about the best gaming build you can get on your budget:
As Mad Admiral said, you want to get rid of the 9800GTX+. It uses a 55nm process which really doesn't matter however its an inefficient card and will just suck up all of your energy make a shed load of heat. Go for the new ATi HD5000 series cards. They are faster and are very efficient and use 40nm manufacturing tech.
I'd recommend the ATi Radeon HD5670, HD5770, or HD5850. Get an ASUS or Gigabyte motherboard. EVGA is mostly an overpriced gimmick in my opinion except for their really high end boards.
Also, try 4GB of RAM for now. Games aren't as RAM hungry as they are GPU/CPU hungry. Also, it adds an extra volt or two when you have 4 sticks running which can limit your overclocking capabilities.
Saving some money there, I would get a Seasonic X650 Gold 650W power supply which is one of the most efficient PSU on the market and one of, if not the best, quality PSU. It's $160 but it is completely worth it and its completely MODULAR. The corsair 750TX isn't modular meaning you'll have a huge clutter of cables in your case....not fun.
