$500 build compatibility

Well, just in my case, I had two CX600 that didn't work properly...would advice a better psu if you can afford it.
I got this to replace my CX600's. Works nice/quiet. (cx600 have a tendency to "squeal" aswell)

As far as the rest of your build, everything else are good choices. One thing I'd do is put in $40 or so more for an i3 or phenom II x4, but that's just me. If you can keep to your budget your more strong-willed than most  

Looks good  

Although I agree with jaraldo; if you can, try to squeeze in an i3-2120 instead of the Pentium.

You should not use that hard drive . Its designed for recording video surveillance not running a desktop computer

You can save some money by using 2 x2 gig of RAM which will not affect gaming performance

get a 6850 and a pentium g840 instead of the 620 and the 6870, that way you can upgrade the gp instead of the processor when the time comes, as video cards are much easier to replace and have more value when sold as used than a used processor does. and you should get the same performance either way.

Here's a build for $605

Thank you very much for all the help.

I would probably go with the g840 or the I3 and the 6850.

Is there any good PSU that is along the $60 price range?

What 500gb HD should I be using?

The build I posted has all that included and has a 560ti which will give better gaming performance than a 6850.

You will get worse game performance with a g840/hd 6850 combo than a 620/6870.

I agree that video cards tend to have higher resale value than processors, but that means you should use a lesser processor and a stronger video card, not the other way around. It doesn't make sense to invest more money in the thing you can't sell.

Whether you use a g620 or a g840, it's not going to have much resale value because the only people that will buy it are ones who's processor died on them. People with sandy/Ivy bridge platforms that are upgrading will buy an I-series processor, not a G-series.

Especially since this is a gaming machine, and even more so because your target resolution is 1920x1080, you want as strong of a video card as you can afford, and you only need enough processor to avoid bottlenecking your video solution.

Luckily, most modern processors are complete overkill for their video solutions. An overclocked 2500k, for instance, is enough for four overclocked 7850's.

A g630 can readily handle a single 7850.

the 7850 is not only the fatest card in this thread (so far   ) at stock speed, it also commonly gets 50% overclocks on stock cooling

make sure to get ASUS GPU tool for voltage controls and higher clock limits if you're overclocking it (works with any card)

Oh, and while the G series processors are all multiplier locked, you can still get 300mhz more or so out of them by increasing the frequency, which will help if you overclock the 7850.

have fun!

If you live within driving distance of a microcenter, check there first. They have good deals, but the best ones tend to be in-store only. For instance, the G620 is $50 there.

you spend more money on the thing you dpont plan to sell you idiot. then it will be useful for longer, and the thing which sells easily and will get outdates faster you spend less on. why spend more money on what you plan to sell and then get a shitty other part that wont last as long at the one that is 20$ extra that wont sell as much? the g840 and 6850 wont play as well, i said that, but it will play better when he upgrades the video card, then the processor wont be a bottleneck like the g620 will be.

This is the board that I would like to use. Can I upgrade to an I7 in the future with this board?

got it.

Try civility.

You're telling him to spend more on the part that will eventually get thrown out.

The 840 isn't going to last any longer than the 620. The performance difference between them is so small as to render it moot. They're barely one tier apart in tom's cpu rankings, which means you won't notice the difference outside of synthetic benchmarks, and any card that would be bottlenecked on the 620 would also be bottlenecked on the 840.

I dunno what bottlenecks you're referring to. A 7850 doesn't even fully use the 620, there's room to overclock the card (even for the 7850's massive overclocks)

The 620/7850 build won't need upgrading for quite some time.

The 620 is slightly weaker than the processor I'm using. The 3x6770's I'm running are oc'd 10%, the cpu is oc'd by 700mhz, and the rig posts 61 fps at 4xmsaa, 1920x1080 in crysis warhead, which is higher settings and fps than these benches.

The overclocked 3x6770 matches the 5970. Given card-equivalences, the trifire 6770's are slightly faster than a 7870; and the x3 handles it easily, so a 620/7850 combo is near perfectly balanced.

have fun!

athlon II x3 is actually quite a bit waeker than then g620 or g840., per core anyways.

Acc. to Tom's rankings, the 455 is the stronger processor. Though if the 620 is actually stronger, that certainly reinforces the argument that a 620 is plenty for the 7850  

ur athlon i smost likely bottlenecking your trifire 6770's.. just saying i really doubt that it isnt.

The 3x6770's I'm running are oc'd 10%, the cpu is oc'd by 700mhz, and the rig posts 61 fps at 4xmsaa, 1920x1080 in crysis warhead, which is higher settings and fps than these benches.

http://www.guru3d.com/article/powercolor-radeon-5770-si...

so unless the i7-965 in those benches is also bottlenecking the 6770's, then the 455 sure isn't.

Thank you for all the reply.

Is the G630 going to bottleneck the 6870?
