All of the components roughly come out to my budget and really isn't an issue.

Questions I have:
1) Any reason to spend another $10 on the factory overclocked video card? Is there really any benefit performance wise? I will primarily play Starcraft 2
2) Any difference between the two memory kits? I am a little concerned with the height of the Ripjaws heat spreader and the HSF. From what I have read both kits work fine with the Gigabytes mobos. Is there any performance differences between the two or should I just get the ones I know will fit without issue?

I am open to suggestions on different parts (within budget).

Thanks
