Is my computer powerful enough?

[freakying99]

For example, if your electricity costs $0.10/kWh and your GPU uses 100W then your power cost is $0.24 (or about 0.0024 BTC) per day. Currently, if your GPU's hash rate is 600 MH/s, then it mines about 0.0072 BTC per day, and your profit is 0.0048 BTC (or about $0.48) per day.

Such GPU exists?
overclocked ATI 5850 delivers 375MH/s and takes 250W

600 Mh/s? yes. at 100W? no. I changed it to a more realistic 250W, around what you would get with a 7970.

I was mining with 8 ATI cards up until about 2 months ago when the power bill surpassed my mining 'profit' - in retrospect I should've kept it up though - the future of bitcoin is largely unknown so if it cost me (for sake of argument these are simple numbers) $100 a month to run a miningrig which was generating 1 coin a month I'd essentially break even (right now) but if the price rose to $200 that 'break even' would be much faster.  Right now I'm mining with a couple of asic sticks which I'm just playing with while I wait for my other hardware...  regardless, you really need to understand that your mining bitcoin, not USD.  If you choose to convert it, that's great.  However, there is a good chance that the prices will continue to rise OVER THE COMING YEARS and your investment (even if it's just power that your paying for) MAY pay off in the long run...

i'm sorry but no. CPU mining is useless. As for GPU, well, you have nvidia cards wich are not good for mining. Sure, your system is powerful and good at gaming and other things but not for mining

Not agree! With this superior for a single PC CPU power he can mine XPM with good success!

Well let's say I bought a handful of the 25GH/s ones from Butterfly instead. I'm trying to look at the big picture here and determine if I'm missing anything, or if this could really be profitable, if  made the capex investment.

Like I said, getting them to your doorstep is the issue. Butterfly labs does not have any 25 GH/s units that are currently shipping and no one knows when they will start shipping. If you order now you will have thousands of people ahead of you in the queue.

BFL is shipping a few of the Little Singles right now but it's just so painfully slow. If I were you I wouldn't buy from BFL. I would get KnCMiner because they have a better $/Gh and they might be shipping right around when BFL clears its humongous backlog, hopefully with my order not lost somewhere.

Ok, so I understand the relative obsoletion of CPU/GPU mining now. So, what if I just bought one of these beastly 50GH/s ASIC miners? If you were me, would you buy one, and convert the BTC to dollars and make your ROI in xx days?

I'd offer that GPU isn't necessarily obsolete.  I have an ATI Radeon 6850 and getting ~ 170 MH/s on it.  It's complementing my other hardware
