1. Is my motherboard overkill for my system?
2. Can I get away with a less expensive model with less features? And still have the same gaming performance?
3. If the answer is yes to question 2, Should I get a less expensive mobo? This isn't exactly a budget build but I would like to spend as little as possible and still have high performance. But is the future proof and specs of the AsRock P67 worth the extra 50 or so since I can afford it?
4. If the answer is yes to question 2 and 3, can you recommend a specific board?
Keep in mind I would like to have this computer somewhat future proofed but I see one of the Gigabyte Z68 models is fairly popular and runs around 50 dollars cheaper then the motherboard I have selected. Currently the computer will only be used for Starcraft 2 and general web browsing like forum posting and such. I will likely be playing a few new games here and there when they come out as well.
I also am looking into the possibilty of running 2 6870's in crossfire.
