Excerpt: If you want AMD performance without the cost, MSI’s K9A2 Platinum might be the ticket. It’s a bare-bones yet performance-oriented board for Phenom procs. Based on the AMD 790FX chipset, the MSI K9A2 Platinum sports four x16 physical PCI-E 2.0 slots. While most boards today sport six expansion slots, MSI goes the max with seven slots. Four are full-length PCI-E slots, two are PCI and the seventh is a dinky x1 PCI-E. You pay a price for it though.
Pros: SAS support and super-low pricing.
Cons: Poor SATA port placement; fallback DOS update method is horrible.
