Well for what its worth to you I own an EPoX EP-9NPA3 SLI running an FX57 OC'd, 2gb Corsair PC3500 Pro RAM @ CAS2, 2 MSI 7800GTXs OC'd and BIOS flashed, X-FI Extreme Music PCI Soundcard, its a rock solid M/B, it OCs well and so far not the first problem has arisen with the X-FI soundcard as some have had.
Had her 6 months now, really don't know what else to tell you, would I buy this same M/B for a second machine? Absolutely!
that sounds like a sweet setup, I'm envious. So what game can't that thing run in full quality....LOL.
