I have one general question regarding my desktop system. I realized the 7970 is a brand new GPU from AMD, and there are only a few cards different from the reference design. I would not have a problem with that, but would those of you who have more experience recommend waiting for other/better models to come out? The reference design already features the cooling system of my choice (blowing out of the case), so I don't know what else could be improved in later versions. Sorry for this being slightly off-topic, I'm still waiting for my actual $/kWh and meanwhile would like to make my desktop profitable. Thank you!
