I haven't had a great computer and I've been dying to build a good one. I don't want to go wrong with products and have to return them so can you guys help me pick a motherboard, power supply, and case that will work please?
The RAM you've chosen is CAS10. Look for CAS9 or better.
Also, regardless of quality (not saying it's either good or bad), I recommend against any Coolermaster parts. Some of their PSUs have liar-labels on them, or claim protections that they actually lack (fact, not opinion; reviews at HardwareSecrets). That's dishonest, and I do not believe a dishonest company deserves anyone's business. Fortunately, in every market it has entered, Coolermaster has competitors who offer equal (or better) products for the same (or less) money. Check out Rosewill's gaming cases and Xigmatek's 120mm coolers.
What resolution will you be running? The 2GB on the 6950 won't come close to being used in 1920 X 1080. If you are planning on running eyefinity, the you would need the extra video memory. 1GB is plenty if you are running at 1920 x 1080.
This card will save you some money, and it comes factory O.C'd with a very good cooler on it.
Yep That's a good PSU, I used a Xigmatek for my friend because it was on sale and still a pretty reputable brand he only had $900 and wanted to get a 2500k (and needed monitor) haha so I found the cheapest reliable other parts.
I have a question as I am shopping around for a build as well. Are there any good ATX mobo's (that aren't mATX's) for the sub $100 range? I'm not looking to oc anything (although factory oc is fine with me.) Between Newegg and TD I haven't had any luck.
Cases I'd recommend the Cooler Master HAF 912 and the Antec 300 Illusion.
And as for going with a power supply, there's any number of PSUs you can obtain for less than $100 but the trick is to make sure they're UL certified and rated at least 80+ bronze or greater. The Corsair Builder Series CX600 is a great place to start, but Seasonic and PC Power & Cooling are also excellent brands.
