Upgrading computer: SLI or new card

[sdimacu]

Planning on upgrading my current computer. I currently have a 470 GTX, should I upgrade to a higher card or just SLI with another 470?

Wow, do you alredy feel the need of upgrading a 470GTX? Well, in that case...

SLI, that will be a cheaper solution, you would have to pay double for a new videocard and similar performance. In addition, the SLI option will gain you a few years when then you may replace the entire system.

SLI and SSD, best upgrades at the moment.
