I would put in
1x XFX ATI Radeon HD 5850
1x Sapphire Radeon HD 5850
, and the total would come to about 600.
Do you think if i ordered these components and build the pc i could return my money by the end of summer?(3 months)

You'd get about ~750mh/s with them.

And I doubt it.

I'm not sure, but with the difficulty increasing every 2 weeks, it will be a while depending on what parts you have, and how much you spend.

At the current rate of difficulty increase you will never break even, even assuming free cooling and electricity.

 I dont like the word never here, there are a lot of ways to turn a few btc into even more btc, mining isnt the only way to make btc its just the easiest to let your pc hash away and be afk

Not in 3 months, maybe 9.  Use a Bitcoin Mining Calculator like the one at: http://www.alloscomp.com/bitcoin/calculator.php
to play around with mining rates and exchange rates to find your break even point.

The market is too unstable to make any real predictions. You might break even in a month (though not likely), you might never. Point is; this is a high-risk investment. Only spend money that you can afford to lose.

Since OP never mentioned anything about trading I assumed this thread pertains purely to mining.

I wouldn't recommend building a mining rig right now, except if you want to use the components for computer games. If you factor in electricity costs and the increasing difficulty, it will take a long time until you break even. You will get about 10 BTC until the difficulty increases, after that you will get less (I'd guesstimate it to be about 30-40% every 2 weeks). So without electrity costs and a stable price of 16 USD per BTC you might be able to break even in 4 months.

I have to pay about 0,35 USD per kW/h (after converting it from my local currency). Your system will probably use about 800W, which would be about 200 USD for me in just one month. So with this rig I would lose about 50% of my BTC to the electricity bill in the first month, and even more in the following months due to the increasing difficulty.

So expect it to be at least 9 months (probably even more or never) with your rig running 24/7 until you might break even.

It's pretty clear to me that unless you have the following things on your side:

1. Free cooling and electricity
2. A reason to have the gear *besides* mining

It's not worth it. I've got a miner running because, well, I bought a decent graphics card for games and other GPU computing projects. By the time most people (including myself) were even faintly aware of Bitcoin, the productivity from production was already pretty shot.

You will never get a return because the network is growing so fast, and you have to compete with everyone else.  You lose about 4% of return each day.  You will start at around $17/day today, but will be down to less than a dollar a day in 3 weeks.  You will reach the cost of electricity in about 60 days.  And in the end you will have $200 worth of bitcoins total for all your work.  I hope you can enjoy the cards for gaming afterwords Roll Eyes

So what if you pay .05usd/kwh? Like me.

I think you're just much better off buying some BTC now and holding. Assuming you've taken the necessary precautions with you're wallet, you could buy over 65 BTC with that rig... unlikely you'll ever make up that difference.
