Having a 3GB card for CloD is definitely an advantage. But, those 3 GB cards are way more expensive than the 1.5 GB versions.
Instead, I am looking into
MSI GTX 580 Lightning - which is marginally more expensive than the reference version and offers significant boost in performance, cooling and quietness. Not to mention the completely custom PCB with a 16 phase PWM (and separate power regulation for memory).
Here are a couple of reviews:
No.1 &
No.2
Thoughts?
EDIT: Resolution: 1920x1080 / 1920x1200, depends on which monitor I decide later on.
