thanks for the help, my current rig is a i73770k with 2 evga gtx 660ti ftw in sli , i can fold on that, but i was thinking i might want to build a cheap rig i can dedicate 24/7 to folding, could i go with a cheap duo core or an amd and get for example a gtx 460, would that be a decent rig to run this on? i want to stick to used parts i can get from Cregslist and such  

With the current state of folding i would wait a month or 2 before you build a dedicated rig. Lower end rigs like your talking use a lot of electricity for little returns. I have 2 like that collecting dust.
 
Once you meet the requirements for the marketplace here you might find some good gear from more reliable seller than you find on CL.
 
please dont let me discourage you any either, this is just my opinion. Every client helps and is welcome here. A cheap rig is also good experience(if you break it your not out alot)
 
welcome to the team

I myself am retiring my q6600 core2 quad core (going to niece as a media/web browser)
It doesn't pay to fold on that for 3k PPD where a 2600k or 3930k does 10x more for about the same power
 
if you're just into GPU then you want the latest hardware too ...PPD/watt is much better.
But if you have spare dough and want to give and use old hardware I can see some people making use of it and just pay the extra dough on the electricity.
 
my take is give to those with less and move to newer equipment on a ongoing basis (replacing computer every 3-4 yrs).

also of note
if IVY-E comes out next year with 8 or 10 core then Bigadv will be back on the table for single socket again
 

thanks for the advice guys, what do you mean by "meet the marketplace requirements"

you need 50 posts before you can PM EVGA staff to get access to the marketplace
 

I'm about to join the team.  It's mainly for the perks, like bucks, and at least this team talks about issues and problems with clients/work units.    I do like that there are "challenges."  
 
I started Folding with TechIMO in the beginning of the year.   I have done many other projects for XtremePCCentral.   Projects like Find-a-Drug got me into this crunching madness for the last 10 years.   When that project ended I tried out Rosetta, but now I'm still running RC5-72 and OGR-27 for XPC due to the simplicity of the distributed.net clients.    (I seen there is a EVGA team for those also). 
 
So.. yeah..  Hello team EVGA, I'm Carl.   
 
Assuming just changing the team number from.. the 111, to 111065 moves me to the team, I should have some points starting today.

Welcome to the team, Carl!
