I was actually looking to get a MSI GTX580 since their models have dual-fans providing better cooling. But since I'm limited to one slot PCIe and can't SLI I was trying to find a model of the GTX590 with similar cooling system because it's like a SLI on a single graphics card.
Also I'm looking to try the Dual Monitor gaming (I have a second similar TV-Monitor that I can use for that.)
As my last thought... I'm always looking to buy stuff that will endure time for longest run possible and since I'm a Crisys fan (and other games of sort) that becomes a little tougher.
