I would also agree with the above poster, wait for Haswell.
For dual cards, they're only necessary if you're pushing into the 2560x1920 monitors, or 3k+ resolution, or multi-monitor setups. Dual mid-range cards is usually not advised unless if you have watercooling and plan on doing crazy OC on them.
There isn't a need for a $3k gaming rig unless if you're going for the 120 hz ultra-high resolution and/or multi-monitor setups. Otherwise, spend at most $2k, drop the other $1k in a bank or stocks, and come back and use it for a future rig 3 years from now.
so if you look at my graphics thread I should probly stay with what I have or go for my future rig idea. And what is haswell keep in mind im on a deployment and cant really get up to date omputer mags out here takes a while always a month or 2 behind.
