@Cyro999: Lots of information haha... The PSU was to allow SLI later, but we already decided to drop to a Rosewill Hive 650W since of the large price difference.
One thing to keep in mind is that this is my friend's first build; I'm not sure how comfortable he will be setting voltages to relatively high levels. I've seen the benchmarks Linus tested from his video, but I've also seen multiple benchmark that contradict his? For example, notebookcheck
(mostly mobile, but has the 7770 and 7970) and benchmarks from Nvidia
(yeah, may be biased). Those both tested Heart of the Swarm rather than WOL, but I doubt the huge differences are a result of that. Also, would you recommend waiting for Haswell then since you seem to be saying sc2 is overwhelmingly bound by the CPU?
I have also heard from multiple online threads that Starcraft seems to favor Nvidia GPUs more than AMD. I can't find many benchmarks with recent examples, but here is one
where the 670 is ahead of the 7960 at ultra settings.
@AlphaC: Are those benchmarks with max settings? Thanks for the deal links, I'll try to get him to pick up the HDD and case tonight. I was not planning on using EVGA stepup and actually was recommended to go with an Asus 660TI rather than EVGA because of better cooling? This is if we still decide to go with the 660TI, which may not be the case now.
@zylonite: I'm pretty sure it'd be difficult to max out with $500 considering he needs to buy OS and monitor.
