I'd like to do some minin on a budget, here's what I'm working with,

and what kind of performance would possibly receive from this set up.

Thanks for any, all input.

1.CPU: Pentium 4 540/541@ 3.20 (stock) Code name ( Prescott) 775 socket

2.MB : will have to buy @ Amazon @ 77.95 free S/H

3.RAM: All ready have 8 GB @ 800 Hz.

4.GPU: All ready have 2 Sapphire R7 260 x oc

5.PSU: Sentey® Power Supply 750w Modular / Erp750-pm / 50ampers / Full Flat Cables / 140 Mm Sleeve Bearing Fan / 12v Single Rail / 4 X Pci-e / 6 X Sata / 4 in all probability I'll replace with something better.

My HD 7770 2GB (a worse but comparable card) got about 0.25 cents worth of bitcoin (in Canadian dollars) per day (over a 24 hour period) on Nicehash when bitcoin was worth more (about $5000 more), so I estimated what the...

Well, don't use your CPU to mine, it won't be worth it. Running both video cards... you might get $0.80 (CAD) per day (at current bitcoin prices, if you use a network like Nicehash); I'm thinking that's the high end. Whether you think that's worth it is up to you.

$80 for a p4 mobo? You can get an entire c2d pc for $50 which will be lower power and better performance (not that performance matters).

Where did you get 0.80 cad a day with btc with 2x 260x? I'm seeing nicehash with 2x 370(which is better) at .00009 cad with no power cost. Btc hasn't been profitable in years on gpus. Eth is showing .89 usd per day but again no power cost so it'll probably be down to about .17 per day with power cost which is not even worth it just to recoup the cost with declining profits.

I said nothing about actually mining Bitcoin, rather, Nicehash pays in bitcoin, which is then converted into CAD. So it's Card>Mined Currency>Paid for Mined Currency in Bitcoin>Converted to Cash (in my case, CAD). I was speaking about the current value of the work done over a day in Canadian Dollars, skipping all the in-between stuff.

Hope that clears things up.

The Nicehash calculator does not list the R7 260. But...choosing the least capable AMD GPU listed, the R9 280x...2 of them...gives you a whole $36.80/month USD, with electricity cost of $0.0. The R7 260x2 will be much less effective.

The Pentium 4, being a particularly power hungry CPU, will easily eat more than that in electricity.

Bottom line - your whole parts chain is significantly subpar for any mining solution.

One thing about the Nicehash calculator: It's not trustworthy - at all. There are huge variances between what the calculator shows and what the cards actually get. Usually the cards make a decent bit more than the calculator (at least from the experience of both me and my brother-in-law): it's why I gave a higher estimation of $0.80 CAD per day for both cards working 24/7.

Oh, and yeah, I usually mine Etherium, but get paid in Bitcoin every week by Nicehash. Kind of like my video card having a job that pays weekly. I don't know where this idea of mining actual Bitcoin came from; I apologize since I wasn't clear about it - no sane person actually mines bitcoin on video cards.

Oh, with only 2GB vRAM, those cards won't be mining Etherium... you'll probably end up mining Equihash (which is z-cash, if I remember correctly).

And yeah, power cost is the big question mark when it comes to mining. Most older cards will eat half the profit in electricity costs. It's why I don't mine with my 7770.
