Another option if you're looking to build in late June and catch a promo for Z77 boards and new Ivy Bridge i5. Should be competitively priced so won't raise that price tag much and power supply, case, RAM, video will all be compatible.
I don't know much about video cards, but I know enough to know it's definitely not on anyone's wish list, but the title of the thread is "$700 gaming PC" and he said $500 to $800 and both of the GPU's you two suggested goes over his budget.
Depends on how close to 800 or over OP is willing to go.
I was looking at the parts, and aparently that motherboard doesnt fit in that case properly, 2 or 3 of the screws don't line up with the mount. What do you suggest about that? no big deal, or change something?
I'm not finding any discussions that show that the ASRock won't fit. Perhaps whomever said it doesn't fit had standoffs where they shouldn't be. I just saw a number of builds with that case and mobo combo. However, I did notice that people say that case can cause issues with cable managment and felt cramped, which is why I had originally recommended the Seasonic modular PSU.
Here are the reviews of those with that case/mobo combo on NewEgg....
