Depending on the game you can gain tons of extra performance or none it just depends on how well it supports SLI. In most games that support SLI you will see a 30-90% gain in performance. I looked at all the Aspire power supplies on Newegg and only one of them supports SLI and it is a 600 watt. Since your came with you case and generally PSU's that come with cases aren't the greatest I am going to say that your PSU probably does not support SLI so you probably need to get a new one to be on the safe side.

Well that PSU has a 34a 12v rail so yes it will.But you will need an adapter for another GPU connector.

I don't own a 6800GS but you should get about an 80% increase in performance with those two running in SLI. It should also OC just like the other card because when you OC in SLI both cards have to OC the same.
