What might someone pay for this system

What mobo? and what brands of video cards,ram,&PSU?

Id say about $300 with no o/s. wont sell well without an o/s either.

If you wnat the most money, sell it locally, or part it out, b/c the parts alone are probably worth more and will go faster then if you try and sell that system as a whole....

try ebay, or w/e, but if u try the local route try craigslist, b/c that system can still outperform a lot of crap that is being sold on the retail market anyways, b/c 2 7800gtx's are still a powerhouse when it comes to the majority of titles, out there, just do some marketing work is all, I'm sure you can get at least 450-550 ish...

Do not sell it on here b/c nobody here would pay as much as you'd like for it, period!
