My 7 year old kid has officially been bitten by the bug. He wants to start folding on his computer which is a socket 939 3500+. I know he can't run the client on that but it's got an SLI mobo so I was wondering if 2 450's running the GPU client would work OK. Or should I take my 260 out and put it in his and 450 SLI mine. I don't want to lose any gaming performance on mine but I want to keep the price down. Any other suggestions would be appreciated. Thanks, Ian.
