Looks good

Looks good, but do you need the CPU fan? If you don't overclock you probably don't need to replace the boxed one.

Only one, possibly two things I'd change here.

1. Change the graphics card to a 660 TI, it's ~$40 more but worth it. I will say though, a 660 won't have massive longevity left in it. It'll run current games fine but will soon need dropping down to medium etc.

2. I don't know the quality of the XFX PSU's so can't comment on that. However, I'd go for a bit more than a 550 incase I wanted to SLI/Crossfire in the future or change any other parts.

Regarding SSD, for gaming purposes it's almost moot since most of the heavy work is in graphics and memory, not read/write files (you'll be seeing a difference of a second or two in loading screens in most games besides the super unoptimized ones). If you're worried about space make sure your case has USB 3.0 ports and get an external 3.0 2T HDD (I think Western Digital sells it at a decent price, depends on the retailer - if you have access to newegg then perfect).

I agree with the GPU switch to 660Ti (most games should run well enough on High). If you're looking to really max out your rig then you should consider a dual GPU setup. It might break your budget though.

WINDOWS 7.

Windows 8 sucks. It's not made for gaming. Also take a 600W PSU. And take 660ti. It will be worth it.

Just buy Win 8. Most of the games will work on since it's base is made from Win 7. There will be some problems with some games but there are fixes that can be found using Google. Win 8 is cheaper and I like really like it. It takes some time to learn it but it's faster than Win 7 and it uses less PC resources (RAM, CPU etc.) than Win 7. I have it as my second system (I have Win 7 Ultimate x64 and Win 8 Pro x64) and I really can feel the difference. And Metro UI isn't that bad as everyone says - when you delete tiles you don't need and put the ones you need where you like it's actually pretty convenient. And you don't need antivirus because Windows Defender comes by default and there's already MSE integrated in it. Sure you can use another AV to scan your computer from time to time but Windows Defender will catch almost all of the stuff that isn't good for your computer. And don't listen to people who say it's not made for gaming - it's almost same as Win 7 and you won't have problems gaming most of the time.

If you have money - buy 2 HDDs and put them in RAID. That will get you a lot of performance.

go for not pirated windows, install original version (whatever you want Home, Premium or Ultimate, no need to buy I think you can download it from Torrents) and you can use it for free for 1 month, then you, in Command Prompt, insert command slmgr /rearm to expand it more 1 month, overall you can do it 3 times (thus you can have official supported Windows 7 for 120 days)

What's a "graphics car"? Also you can totally play maximized pinball with those specs, i envy you!

You probably should go 7850/7870. They perform better for less (at least in the US).

what? buy? windows? original? rofl

As far as the OS goes, I would recommend windows 7 as long as it's 64-bit.

CPU - Sweet! But if you want to save some money and you're not gonna overclock it, buy the non-K one.

CPU cooler - No, no, no... This could kill you, buy a proper cpu cooler or go with the stock one. I'd take at least the Scythe Mine 2, maybe the Gelid Tranquillo, or be a classic and go with the Noctua ❤❤❤

Ram - 8 GB is good enough for gaming, and the brand, well, it really doesn't matter that much. If you can get cheaper sticks by Kingstone or Corsair with a passive cooling, take them instead. The difference is negligible. Just make sure that you're buying two sticks (2x 4GB), not just one...

Motherboard - Pretty good choice, I'd go with this one if you don't want to save money on the motherboard.

GPU - Yup, sweet GPU. If you have some money left, go with the Ti version. But this one is powerful enough too. And about the cooler on it, I usually build PCs with the MSI cooler, but those Gigabyte are very popular as well, I just don't like the blue PCB :D. So it's up to you :)

PSU - Yea, 550W+- is enough. Altough I'm not sure about the brand, they don't sell these in my country. I'd go with the Seasonic M12II-520, or with the Seasonic SS-500ET F3 if you want something a bit cheaper. But this one won't look so good in your case because it's silver :P. There is also option to go with a better Corsair one, or with the Enermax. But the Enermax's PSUs are quite expensive.

HDD - BUY AN SSD! Seriously, it's a huge difference! (not in gaming performance) I'd rather spend less on the cpu/gpu/mb to be able to get an ssd.

Case - If you like the case, yep, take it. It's a proper case. Although it has an open side with a huge fan, so it's gonna be loud as sh*t. If you want something more quiet, look for something with closed sides panels and with noise-reducing material. Like the Fractal Define series, but well, it's up to you what you like and what you want ;-)

OS - Go with the Windows 8, the Windows 7 is mainstream today, but it's not gonna be in a few years. So why would you buy older OS, right? :P

Definitely get Win 7(x64), Win 8 is just Bill's another fail (id say its already a tradition for him, to release s**tty OS's after a successful ones as it was with Millenium and Vista). Other than that, this set will definitely serve you for a long time.

i'd get a gtx 670 instead of a gtx 660 or gtx 660 ti. The gtx 660 and 660 ti are bottlenecked by their 192 bit memory interfaces. The minimum fps benchmarks really highlight the memory bandwidth issue, especially in Crysis.

For the OS windows 8 has DX 11.1 while windows 7 has up to DX 11. DX 12 is likely not going to be supported by windows 7. I have a feeling most people who are saying to get windows 7 will upgrade to windows 9 to get DX 12. So if you chose windows 7, then your probably going to need windows 9 down the road. Or you can choose windows 8 and get DX 11.1 and hope it gets DX 12. Anyways my favorite OS going from best to worst is windows 95, then xp, vista, 7, and 8. Vista, 7, 8 have a lot of compatibility issues with software before 2000. I don't understand why a complex coded OS cannot run code from a simpler OS.
