ADDITIONAL COMMENTS: I'd like a quiet PC. Something that will have good audio (won't give me problems if I want surround sound etc.) Most importantly most economical/lasting/upgradable build possible...

I have decided on a Ph II 4 955 am3 over 1156 for hopefully *some* future proofing down the line. I decided on a gtx 460 after seeing gpu benchmarks from anandtech and would like to get another for SLI in the near future. This limits me with my motherboard options and that's kinda what I'm looking for advice on.

Also I was pretty much set on an i5 build 2 nights ago but changed my mind after delving deeper into the forums and reading Intel isn't going to be using 1156 sockets in the future.... Everyone says this is the build to get for SLI though so I am conflicted about this once again...

Antec 300 case

Only went with the XFX PSU becuase of the combo... Does anyone have experience or knowledge of it or the brand/think it will be enough? Was also considering getting one of those killer gaming network cards but would that fit in with my mobo+SLI? Need some advice in general.. Don't need a keyboard/mouse/monitor either.

Does anyone see any problems with bottlenecking using this mobo/ram and 2 gtx 460s?

tl;dr
Should I buy all this stuff?

Thanks!
