I'll leave that up to you. I posted 8 different PSUs that you can choose from. ;)
Regarding the video card, this is good timing because here's something I posted on SevenForums a couple of hours ago:
why isn't the 640 good? its 128bit 2gb
The GPU's processing power is relatively weak for today's modern games. It's basically just a simple video card that's not really intended for gamers. Compare specs like the CUDA cores, Graphics Clock, Memory Clock, Memory Interface, Memory Interface Width, as well as whatever else you can find to compare. For example, the GTX 650 isn't that much better in terms of the CUDA cores and Graphics Clock, but the memory specs are significantly better. Then if you step it up to the GTX 650 Ti, you get a huge boost in the number of CUDA Cores which helps tremendously for 3D performance.
Of course, it definitely depends on how much you can afford. I mean, if you want some serious 3D gaming performance on a budget, then I would look at the GTX 650 Ti at minimum. Or if you can afford it, the GTX 650 Ti BOOST. The BOOST version has the exact same memory specifications as the GTX 660 with a tiny improvement to the Graphics Clock and a few more CUDA cores (in comparison to the non-Boost version of the GTX 650 Ti). Of course, the GTX 660 provides another jump in the number of CUDA Cores which helps. Then there's the GTX 660 Ti which gets a big jump in the number of CUDA cores, but it has the same memory specifications as the GTX 660. Still, the big jump in CUDA Cores makes it noticeably faster.
The number of CUDA Cores is what helps the most, but everything else helps too (of course). The memory helps in processing textures and anything else that gets put in there. So, choosing a video card can be pretty easy when you know what you're looking for.
On AMD's side, I'm not really sure yet what to compare.
So yeah, the GTX 650 Ti seems to me to be a good choice, but anything less doesn't seem worth it to me.
