7800 GTOC vs Two 6600 GTOC's in SLi (all BFG)

[Jason]

I'm considering picking up the 7800 GTOC from newegg (they have a $30 rebate going on right now which puts it at $320 after rebate).

I'm having a little difficulty figuring out, however, what the performance difference would be between one BFG 7800 GTOC vs two 6600 GTOC's since they both come overclocked. Would it be similar comparing just standard 7800 GT to 6600GT SLi?

Also, if I were to sell my BFG 6600 GTOC, how much would be fair? Newegg sells it new for $189.

The 7800GT would stomp 2 6600GTs...

Given that a 6800GS costs $200, and will outperform both your 6600GTs in SLi...I can't see you charging much more than $250 for the pair and getting any kind of response...but people are stupid...so ebay may well prove me wrong...

For future reference, typically the overclock on BFG cards isn't enough to change benchmark results that much...it gives them a little boost...but nothing that would put the card in a different class...

What I'm asking, really, is should I buy another 6600GTOC (to make it SLi) or should I sell my 6600GTOC and buy a 7800GTOC?

I think you pretty much answered my question though.
