Thinking about my first build. Are these parts good?

Hello! :D
(I'll apologize right now if it's too long. Also apologize for my lack of tech-savvyness.)

I've been thinking about building my first computer, as the one I'm currently use is certainly outdated: sometimes while multitasking, it'll freeze for a moment (e.g. listening to music and browsing on the internet on content-heavy sites), it practically can't run modern games (Sometimes they'll run, with horrible lag even at lowest settings. Sometimes they wont run at all.), and sometimes it even outright freezes and needs to be rebooted (again, while multitasking. ). I'm not very computer-savvy, so bear with me if I don't understand something.

Note that ALL the components on the computer I'm currently using are all stock, from when my parents bought it for me. It's a pre-assembled PC, obviously.

So I've done some research on parts to build a new, more powerful computer. Are these parts good? Any suggestions? Are all these parts compatible? I'm kind of on budget: I'll buy used from Amazon Warehouse Deals whenever possible, and I plan to buy on Black Friday (If everything works out - otherwise it'll have to be delayed to somewhere around January 2014)

Motherboard: I've been really, really torn on this one. I think I'll go for an ASUS Crosshair V Formula-Z, as it seems to be the best AMD MOBO... I'd really like to try and have a system that will last quite a bit of time, until I run into the same situation my current PC is in.

CPU: AMD FX-8350 seems to be the best bang for the buck. While I do plan on playing games (I've heard Intel is better at that), I've also been interested in Video Encoding and other things that require more cores and threads and stuff. I haven't bothered to try at all on my current PC (because it'll probably take one million years). I think I'll stick with this CPU, so I'd rather not read Intel recommendations (nothing against the company; I just need cheap stuff. They're too expensive for me, I think).

PSU: I haven't checked if the PSU for my old PC will work on the new components (Hopefully it will), but just in case, I went thru Corsair's PSU Finder (or w/e) and it recommended me a Corsair CX model (modular version). It'll most likely go for the 750w model if I need to. It also recommended me a TX model. I'd like to ask: is there a risk on reusing the PSU? I have faith the stock PSU is of good quality (shouldn't fry anything, and it's been working fine for the last... 4 yrs or so). What happens if my PSU is not strong enough? The computer simply doesn't turn on? Or is there a risk of damaging other parts?

GPU: This is where I really need help. I've decided to go for an AMD Radeon HD 7950. The problem is that there are so many different models, I don't know what to do. I was considering this Gigabyte AMD Radeon HD 7950 3GB, but reading the negative reviews... Apparently it has compatibility issues with some motherboards? That really worries me. Also, some people say it's voltage locked (not that I'm 100% sure what that means, but...)? I'm looking for a GPU with a good cooler and the best bang-for-your-buck. I don't mind nVidia (I haven't really checked their cards... Are they more expensive?)

HDD: I'll probably be reusing my old one. Would there be a problem, such as compatibility issues? Much like my PSU, I haven't checked this. I'll probably upgrade in the future

SDD: Maybe later.

Optical Drive (that's what it's called, right?): I'll reuse the one I currently have. There shouldn't be any problem, right? It's a DVD+RW drive.

Case: Surprise surprise, I plan on reusing the one I currently have. I'm not very well versed on these things, but is an standard-sized case (ATX or something?) AGAIN I haven't checked if it's big enough on the inside (I doubt there'll be problems, anyway). What worries me is the ventilation... I'll probably use a makeshift solution (e.g. leave it open) if it gives problems until I can get a better case (again, if it gives me trouble). Aprox. measurement of my case is:
Height: 36,2 cm. Lenght: About 40 cm. Width: Around 17 cm

RAM: I'm thinking 'bout purchasing 32 GBs, but most likely later.

OS: Don't need to buy ;)

I think this is it...

Other data:

Overclocking?: Maybe. I'd like to have the option to do so in the future, because I may not try to overclock everything right away.

Crossfire/SLI: Maybe. If I have enough cash to buy 2 cards (most likely NOPE), I might try it out.

What do you want your PC for?: A bit of everything. I want to play modern games at least at 30 FPS (preferible that these 30 FPS are from the highest possible settings, but I'm not very picky on graphics.), but I also want to try out video encoding, maybe even video editing! I also want to multitask without risks of my PC locking up (either temporarily or that I need to reboot it), and that things, in general, run smoother. Like butter.

Part preference: AMD

Site preference: Amazon.com exclusively (my parents only buy from here, even if other sites are also trusted)

Location: Guayana City, Venezuela (I have the feeling RMAing will be a problem... Is it rare to get DOA parts?)

My PC's Windows Score (it's in spanish, so it may not match the terms from the english windows version 100%):

Processor: 6,0
Memory (RAM): 5,5
Graphics: 3,6
Game graphics: 3,4
Main hard drive: 5,9

Any help will be appreciated :)

For that build, you won't need 750W. 600W would be sufficient, and you'd probably get away with 550W.

I would recommend XFX or Seasonic over Corsair though - they exceed Corsair's quality. XFX PSUs are also reasonably cheap too.

also, I'd recommend the GTX 760 over the 7950 - it's cheaper, and outperforms the 7950 in some circumstances. It can be overclocked quite a lot as well, allowing it to easily surpass a 7950.

Additionally, NVidia have some pretty trendy features that aren't found with AMD. Whilst I have always been a fan of AMD graphics, Nvidia have come up with some pretty interesting stuff as of late, hence why I'm getting a 760.

Thanks a lot for replying.

Do you have an specific PSU model that you could recommend? I'm looking at this one.
So I should go for a GTX 760? What is the best brand? EVGA?
In such case... Which one do I pick?

I guess the SuperClocked one?

The pleasure is all mine.

Yes, that one would be perfect :)

And yes, the GTX 760 would be ideal for you - I'd recommend the MSI Twin Frozr one - EVGA's version is subpar compared to their usual quality, which is a shame (somebody informed me of this today, with evidence and statistics to match, that showed that the MSI Twin Frozr version is the best of all).

Yes, the MSI GTX 760 Twin Frozr OC version :)

This one, I guess?

Another thing, by the time it's Black Friday (or January 2014), are there any upcoming releases I sould look foward to? Assuming they are under 300$, that is. For example, a newer, more efficient AMD MOBO, or Processor? Something like that?

(I'm asking so many questions...)

Thanks for all your help :)

Yes, that's the one :)

And to be honest, I don't know. I live in the UK, and Black Friday is not celebrated here. However, I would imagine that something will come up by Black Friday. :)

And it's fine! We are here to answer questions that people might have :D

Thank you :)
I think all of my questions are answered. I really, really appreciate all of your help.
I can't wait until I get to buy all the parts I need :D
