Honestly, I think the smartest move would be to just get rid of that 7770. Personally, I could probably offload any of them for $167 without much trouble. If you can find an R9 280 or an HD 7950 for around 1000, those would actually outperform a dual 7770 setup anyway, which might be a good way to sidestep all those annoying CrossFire headaches altogether.
It really depends on what kind of deal I can put on the table for you. Honestly, if you’re just sticking with that Intel Core i5-2320, a B75 motherboard would actually be a decent choice since you aren't going to be able to overclock it anyway. But, if you're planning on running two graphics cards in CrossFire, then you're definitely going to need something more high-end like a Z68 or a Z77 chipset. What else are you running in your build right now?
EDIT: I just noticed you've got dual 7770s. In that case, you'll need a board that supports that specific socket (either Z68 or Z77) and specifically one that offers at least two PCIe x16 slots capable of running in x8/x8 mode. For instance, this ASRock model should handle that just fine.
The H97 chipset actually gives you the option to upgrade to those next-gen Intel Broadwell processors later on. I guess if you aren't really worried about having that kind of headroom, you could probably just go with a cheaper motherboard instead.
If you’re going this route, I’d suggest picking up a reputable brand-name power supply. Personally, I suspect 4GB of RAM should be plenty since you aren't tackling anything particularly demanding. It's also pretty easy to upgrade later on if things change. You could even ditch the dedicated graphics card entirely; Intel's integrated graphics shouldn't have any issues handling HD video playback. An NVIDIA card might just end up being an unnecessary drain on your power consumption

I honestly don't think you need to sink any more money into this than what you've already listed. That GPU is plenty solid for 1080p gaming, the SSD will keep the system feeling snappy, and I’d probably stick with an Intel processor since I doubt you're looking to mess around with overclocking anyway...

Upgrading to what, exactly? Some next-gen x4 processor that might squeeze out maybe a 10% performance bump? If AMD were actually planning to drop an x6 APU, then we’d have something worth talking about actually.

It’s not just about that, though. The 260x actually has 128 more stream processors and 56 versus 48 texture units, so I guess a 15-20% difference is probably a more realistic way to look at it.
So you’ve eventually hit that $1167 mark, which I suppose is the threshold where it actually makes sense to drop in a much beefier AMD FX-6300. Doing that would pretty much clear the way for you to install significantly more powerful graphics cards down the road. If you decide to go with the Fortron 400W instead, the cost ends up being $33 lower by about . 1 x AMD FX-Series X6 6300 Processor 3.5GHz, 14MB, 95W, AM3+, FD6300WMHK 1 x Gigabyte 970A-DS3P, AM3+, AMD 970 SB950, 4x DDR3 2000(O.C.)/1866 1 x Sapphire R7 260x 1GB GDDR5 OC, 1GB GDDR5 128bit, 28nm 1 x DDR3 4GB (1x4GB) Kingston, 1600MHz, CL11, Value 1 x Intel SSD 120GB 520, 2.5", SATA III-600, R/W:550/520MB/s 1 x Fortron 500W Power Supply, Hyper-Threading, PPA5005003, 12cm fan 1 x NVIDIA Kepler Rev.2 cooler, 1156/775/FM1, 96.5×51×125 mm, 92mm 1 x MS PHOENIX case without power supply, Midi tower MBO: ATX, mATX
I’d say the Intel Pentium G3258 is probably the better choice here since you can actually overclock it, plus using an LGA 1150 motherboard gives you much more breathing room for future upgrades later on.

$43 is basically a toaster. You could probably throw in 2gb + 4gb of RAM and maybe that would bring the total up to exactly $5,000 with the toaster included. Honestly, 6GB should be plenty for gaming, I guess. That wireless adapter ought to work without any major issues too.
