The newegg video on the CM Hyper 212 EVO shows that the heatsink pipes on the evo are actually touching at the bottom of the heatsink as opposed to not touching on the CM Hyper 212+. The reviewer suggests that because there are fewer spaces for hot air to build up on the evo, and because the copper pipes touch the cpu continuously, the evo should transfer heat faster/better. Also, the evo has a bigger faster fan that can push more air.
The CM Hyper 212+ = $26.99
The CM Hyper 212 EVO = $34.99
So for $8 bucks you can get more air push and a better heatpipe to cpu transfer.
I think your best option is to go with a 700W PSU with that NVIDIA 570. Otherwise, nice setup and everything!
Dont have enough money for a 700w psu and I think that It would be more convenient to save $100 now on the gpu for almost the same performance and use another $50-100 in a year to get another gtx 560 ti and get extreme performance.
I think that if you want to go with a 560 ti and have plans for going SLI tuen downgrade to the 560 ti,but be SURE to get at least a 700W PSU rated gold because a 600W PSU wont be enough for 2 560 ti's in SLI.
I generally figure that if you are going to go w/ a single GPU at first, and get a second of the same one later, that you go ahead and get the better GPU (GTX 570) instead of the cheaper GPU (GTX 560ti) so that you get a bigger improvement when it comes time to get your second card (final GPU upgrade w/out all new GPU's).
With my limited knowledge, your build looks like you are getting some nice bang for buck. The Corsair 400R is a nice case, and is supposed to offer some of the best performance and features out of any case in the $99.99 range..... Or so says this Corsair Representative...
