Maybe on winter holidays I'll format my test machine and install Win10 there. 
I thought, Intel Pentium D 945 with 4 gigs of RAM and NVidia GF 210 would be enough for it.
I believe you said once that you managed to get your system running with 2 NVidia cards using SLI. Please tell me this:
1) To get the cards to run that way, is it a simple matter of connecting the SLI bridge, or is there more to it than that?
2) I know both cards must be NVidia, but do they have to be the same model? For example, can you pair 1 GTX-760 with a GTX-660, or must they both be the same?
3) If all you have is 1 monitor, do you just connect it to either card or what?
I ask because I'm thinking of adding another card and run it in SLI with my current GTX-660
