New build, Best Buy Only....Using CC

Hello All,

So I'm looking to do my first Pc/Gaming Build and I need some advice, Heres what i'm looking at:

1) PNY - GeForce GTX 560 1GB GDDR5 PCI Express Graphics Card

2) EVGA - P67 FTW Desktop Motherboard - Intel P67 Express Chipset - Socket H2 LGA-1155

3) Western Digital - Caviar Black 1TB Internal Serial ATA Hard Drive for Desktops

4) Corsair - Vengeance 4-Pack 4GB DDR3 DIMM Desktop Memory Kit

5) Intel - Xeon E3-1230 3.20 GHz Processor - Socket H2 LGA-1155

6) Cooler Master - CM Storm Scout Mid-Tower Chassis

Creative Labs - SoundBlaster X-Fi Titanium Sound Card

Corsair - ATX Power Supply Model: CMPSU850HX

So I tried to do my "Best" with what they had at BB , Not too big on the case, prob pony up doe else where.
My big issue is price, its totaling out to 1200 without Windows or any other minor things. I was wondering if there is any way I'd be able to keep it around 800 to 900 without downgrading too much? Is there maybe a better/Price options on there site or should I buy the Graphics card elsewhere to save money? I'm kinda a noob, but have enough knowledge to build so just looking for advice/Tips.
Thanks for any help given guys, I'd appreciate it!
