This is my first PC build and I don't know much about hardware, I tried reading many posts here and in other sites but I didn't get a definitive answer to my question
So, I'm on a limited budget ( around 900$ max.) and I need help choosing between

sapphire HD 7770 vapor-x 1GB OC (around 145 $ in my country)
http://www.sapphiretech.com/presentation/product/?cid=1...

or Sapphire HD 7850 2G OC (around 220 $)
http://www.sapphiretech.com/presentation/product/?cid=1...

and for cpu

FX 8120 (around 170$)

or Intel i5 3470 (around 200$)

I want to run games on the highest quality and HD movies ( I prefer best Performance/Price ratio)
any other suggestions are welcomed

P.S. what is the best mobo to go for and is a PSU 500W sufficient for this ?

Thanks in advance.

7850 + the i5 (if you can afford it)

Should run every game on maximum on 1080p resolution

The FX6300 is $40-$50 less expensive than the FX8120 in the US -- not sure if that applies for you.

The point being, in a gaming rig it's your video card, and jumping up to an HD7950 if possible is what will have the greatest impact on your play.

FX6300 is around 140$, not sure if its available in the market though
however FX 6100 is around 125$, But its around the same price intel i3 3220(but how long any of both can be used before being upgraded ?)

As for HD 7950 it costs around 340$ ( seems too high for its increase in performance, and won't it make a bottleneck with the fore-mentioned CPUs ?

The FX6300 will push the HD7950 quite well.

The FX6100 *Bulldozer* is gimped compared to the 6300 and will work, but will run hotter and not OC as well.

Most games barely use 2 threads these days -- that's why the i3 3220 is such a great option BUT ....

The new Haswell CPU is s1150, not s1155 ... on an AM3+ build at a minimum you will have the option of upgrading to the next-gen Steamroller in late 2013 or 2014.

i5 and the 7850. Although i'd go 7950 now since its getting much cheaper.

I'm not sure what this sentence mean, would you care to explain it a little?

In May/June Intel is introducing their next-gen Core processor. The code name is Haswell, and the processor requires a new motherboard, s1150 (as opposed to Sandy/Ivy s1155).

I'm not certain, but everyone has *presumed* that s1150 will support the next-gen Core CPU after Haswell, which is called Broadwell, due in 2014.

Thanks for explaining
well I guess I'll go for the i3 3220 and hd 7950 vapour-x 2gb oc
what is your opinion on this mobo
Gigabyte GA-990FXA-D3 motherboard
and will a PSU 500w handle this well or do I need more power and/or cooling?

got a website u can guide me too?

id recommand a 550watts atleast.

the ga-990 is nice as well

The -FX series are great motherboards but not really needed unless you plan to Crossfire/SLI (run 2 video cards). If this is not your intention, I would recommend that you purchase a Gigabyte *UD3* motherboard as they are more 'durable' with advanced 8+2 power phase VRM with cooling-sinks on the FETS.

The Gigabyte GA-970A-UD3 would be an excellent choice for a single video card.

I suspect 500w would work but I do not know the specific requirements for the HD7950. The HD7950 runs really cool (even when over-clocked 20%!) but as pointed out by iceclock I'd go with something in the 550w- to 600w-range to cover any future additions (fans, controller cards, HDDs, etc) and any over-clocking.

The FX6300 (and the HD7950) are each silly-easy to over-clock :D

At stock, especially the 95w FX6300, they're not so bad. The 125w FX83XXs can get a little toasty.

The OP should get a sweet little OC on stock cooling without too many problems, but 4.7GHz would need after-market cooling - LOL
