This is a much better build for 500 bucks

You didn't add anything to "Storage", so I'm guessing you already have a HDD.

It was such a close game, 5-4. GG, was a great match and thanks to meb for casting this!

Just played his team and he was making some good plays as roamer. Someone should definitely mentor him!

This is a pretty nice build, but I recommend replacing some components

SSD: http://www.newegg.com/Product/Product.aspx?Item=N82E16820211597
(SandForce based, so it's much faster than the M4.)

Also, you can try using the new Haswell CPU. It actually might be better than the FX-8350. I can't confirm that at this moment.

(On sale for $199.99 in another website)

MOBO: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128601

LASTLY, if you want more performance for higher-end games, you can downgrade your SSD to 128gb and get an EVGA GTX 770 Superclocked w/ ACX Cooling Unit

GPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130921
(The new ACX cooling unit is like 10c cooler than the stock EVGA design. The fans are also supposed to last 12 years, according from EVGA.)

128gb SSD: http://www.newegg.com/Product/Product.aspx?Item=N82E16820211596
(The weaker chip is on for this SSD, so you actually get 128gb instead of 120gb)

Make sure that you put your autoexec in tf/custom/UserStuff/cfg. If you don't have UserStuff, create that as a folder

They pretty much have the same overclocking abilities. It's just that the UD5 has 5 PCI-E Slots and 8 SATA 6gb/s while the UD3 has 4 PCI-E Slots and 6 SATA gb/s

Mushkin makes some pretty nice RAM, so that's good enough. Also, I recommend using the GIGABYTE-990FXA-UD3 instead of the UD5.

BASICALLY, get a power supply that uses Japanese Capacitors. XFX uses the same parts as SeaSonic, so that's an alternate option.

530W is plenty for this build.

This isn't very good since the A10-5700 has integrated graphics. In order to run dual graphics with the APU, you need to use a 6670.

Since you're planning on using your 5770, I recommend buying a desktop that uses the i5's integrated graphics since you'll get more performance out of your CPU compared to an APU.

Desktops using the i5 graphics cost around $500-600.

If you're looking to stream/overclock, I recommend this build.

You'll have $135 left to get some peripherals

EDIT: Silly me, I forgot to include a case.

Of course it would, if you don't get a GPU that's going to bottleneck the CPU.

The FX-8350 gets a tad less FPS than the i5-3570k, but you can get much more streaming performance. Those 4 extra cores make a difference. Also, of course you're going to see stutters if you use a low-end CPU.

P.S, Some Intel CPUs use the same 32nm architecture as the AMD CPUs. I'll list a few.
