Where should my 5GH/s go?

Topic says it all really. Right now I have two rigs running with 7x 7970's, and I've been mining with EclipseMC as DGM, but I'm wondering if maybe there's a better pool out there that I could apply my 5GH/s to? I enjoy EclipseMC's perks, such as

Google Voice-compatible SMS messaging (!)
~~Paypal~~Dwolla instant cash-out option
Fancy added-security authentication options
Fairly high pool mining speed, for fairly quick block solving (and thus fairly quick payout via DGM)

Any opinions?

Also, at the moment, I'm mining as DGM, but I'm wondering if with 5GH/s I should switch over to PPS or some other variant. My (likely wrong) understanding of DGM is that you're paid a set amount based on your hash rate, not so much based on the number of shares you contribute in a round.. but wouldn't that mean then that I would want to switch to as fast a pool offering DGM as possible? And I haven't done too much investigating into whether I would make more as PPS than DGM, but can anyone shed some expert opinion into this? I'm just a hardware guy at heart, trying to earn some moneys. Halp?
