advice on my $781 newegg gaming build?

Graphics: 5770 or 4890, depends on you. 5770 has dx11 and less power consumption whereas 4890 has better performance. Do you plan on crossfiring in the future? If NOT, I would recommend the 4890. If so, then I'd get the 5770 as I've heard raves about how well xf 5770s perform.

Processor: IMO, downgrade or upgrade. I know you are opposed to overclocking but you could easily tickle the fsb settings or multiplier and get 3.4 from a 955. That said, phenoms ARE overclocking processors. They come with unlocked multipliers to make overclockers happy. If you are reaaaaaalllly opposed to overclocking, I would (imo) shell out $15 more for an i5 and get an intel mobo.

So,   to overclock = get an i5
And,   to overlock = save $20 and get a 955, overclock to what you're comfortable with.

Motherboard & PSU: I'll talk about your options for mobo & psu dependently. Your PSU choice is excellent but you won't need that all that extra wattage if you aren't planning to XF (which may be the case now that I've seen your mobo choice).

[Note that with 1 card, you don't even need 650w, its just that the corsair 550w on newegg only has a $10 MIR, so their 650w psu would definitely be the better deal; this is just corsair too]
You can go even lower with this psu, $40 after MIR:

IMO, corsair manufactures awesome psu... but its awesomeness, while appreciated with 1 vid card, isn't really necessary. I wouldn't trust any other brand when in XF/SLI though. So you sacrifice some quality, but OCZ isn't that bad either :].

IF you do plan to get another video card (which i hope would be a 5770 if you take my previous advice), then the corsair 650 will also suffice. Remember, 5770s are more efficient and less power hungry than 4890s.
And if that's the case, then you'll need a SLI capable board.

A bit for expensive, but x16 at full speed (which, since you want Crysis on high settings, I think you will greatly appreciate)

Runs at x8/x8 but cheaper

That's for AMD.

Intel (in case you're thinking of an i5)

Not sure if the pci2 slot runs both at x16, but in case, it's a value deal.
You get the picture.

I've never used A-Data RAM, so I cannot comment on that.

I suggest picking up one of the cases they have on BF sale
Antec 900:

CM HAF922:

You probably won't find those cases that cheap; at least not anytime soon.

Everything else is fine. I would have suggested a caviar black instead of blue, but they are sold out. (Partially thanks to me  , yay new boot hard drive)

Let us know what you decide.
