My Rig, Your opinion

Never heard of your PSU , and since you havent given a link Im going to guess and say its junk . Use only 80+ bronze or better power supplies . 450 watt would be enough

I would tend to use the FX 4100 and just overclock it to 4170 speeds. In all other ways they are identical , or if you can afford it then the FX 6300 which uses less power and gives better performance

Make sure the RAM is 1.5 volt or less

Gaming performance is dependent on your graphics card, and your screen resolution more than anything else . High resolutions screens have more pixels for the graphics card to calculate so games run slower or you have to reduce detail settings. The 650 loooks like a decent budget card butits not going to play games like BF3 on high image setting at 1080p

For around the same price a Radeon 7770 gives a little better performance

No, it will not run crysis or far cry 3 at maximum settings with a 650, that is with a 1080p monitor, see if you can get a 650 ti or 7850 from amd(the 7850 being the best choice).
That psu is junk, it's made by great wall.
Get a decent one from corsair,xfx, seasonic, antec, pc power and cooling,fsp,ocz within 450-500w.

Psus from Corsair and so on cost 2X more than that... not in my budget sorry What about just getting a case with a built-in 500W PSU?

As for the GPU i think this one is good enough, like outlander there said...

http://www.asus.com/Graphics_Cards/HD7770DC1GD5V2/

The ram is 1.5V

That power supply is complete crap - you should definitely not purchase it.

You don't need the extra thermal compound - your fan will come with some good solution.

What store are you buying from? If you post that it will help to suggest parts.

The gpu is good, the ram too.
But it's wise to get a better psu, i doesn't have to be from corsair, there're other good brands too, but the one you listed isn't good.
It will power a 7770, but if you can find a better one within the price, it will be better.

What is the price of the corsair CX 430 ?

What are your opinions on the Cheiftec A-135 aps-500s?

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

It's 60€.

Either that or the Spire Black dragon 500 500w

http://www.mimovrste.com/artikel/2400004111/q=napajalni...

And I'm ordering from MIMOVRSTE, a slovenian company, where i had good experience before.

http://www.mimovrste.com/

Thanks, Iceclock for some ideas, but here in Slovenia those things aren't as cheap than in USA, UK... although you definetely changed my mind on some things...

Oh, Iceclock, are you talking about this MOBO? http://www.mimovrste.com/artikel/2380005018/q=GigabyteG...

Tell me what you think of it! Thanks!

So, here's what i got till now.

I hope it'll work out togheter. Please just tell me if it's all compatible, if the PSU is powerful enough and if it will run games! Thanks again!

hope you can see the picture.

Ok, so i forgot the fan, so i got a cheaper case.. sorry. here's the final one:

http://imageshack.us/photo/my-images/32/asd2fu.jpg/

yeah looks, good but that ps isnt good.

id stick with corsair. xfx. seasonic. antec. pc power and cooling,. be quiet brands.

looks good except u need a better powersupply and want 2x2 ram kit not 1x4gb stick

But the corsair is the cheapest ram in my store and the cheapest 2x2gb is 32€ and it's 1333mhz!

Anyway i got a new PSU there the Corsair CX500

http://www.mimovrste.com/artikel/2400005314/q=napajalni...

well atleast thats an improvement. id go with that cx500  

also if u just get 1x4gb ull be running in single channel and thats slower than running dual-channel.

http://en.wikipedia.org/wiki/Multi-channel_memory_archi...

Well thanks for your help, as for the ram i'm building this for someone whose not that picky anyyway  

Will the CPU n MOBO fit together?

ah yes it will.

Chefitec is another brand that makes garbage power supplies. You don't want to skimp if you can help it. That Spire one also looks pretty sketchy. Don't go cheap on the power supply otherwise it will likely blow up on you and take your system out with it. Tread carefully here. I'm searching that site to see if I can find anything but man those prices...  

Thanks G-unit1111, but i already found a PSU from Corsair

http://www.mimovrste.com/artikel/2400005314/q=napajalni...

As for the Chieftec, i have a 850W chieftec for 4 years and it works great. But it was like 120€, so it's preety good i guess  

yeah the corsair works great. doesnt mean that it worked for 4 years that it couldnt of blew up ur pc parts. somethimes thats like playing russian roulette with ur pc
