Topic: Which Card Has The Fastest ROI? (Read 7063 times)
easiest way to get an adrenalin rush every time your boss step inside your office, i guess
Nothing like risking a full time paying job for a few £ in electricity.

I never understood people that try to shove a GPU into a work PC because of 'free power'. So, let's lose a job that makes more in an hour than we'd make in two weeks of mining. At some point someone is going to hear the GPU running, notice the power spike or the web traffic going to a mining pool. Try to explain to your boss and HR what 'this bitcoin thing is', and see what they look like when you start talking crypto currency.

I got a 7950 to stick in my work PC for the next couple of months, cost me £220, should hopefully earn £80 - £100 before its no longer worth running even with free electricity... then I will sell my 6870 from my home PC and hopefully it should work out as a pretty GPU upgrade for my gaming machine, probably just £50 difference

Ekkk, not good.
what card has a better ratio for litecoin mining than bitcoin?

Ati 5830's you can get 'em cheap <$99 and they overclock good and still stay cool unlike 5770/6770s
270MHs (875/500/66c) for $99 thats 2.72Mh/$ ROI
I even see one on ebay $75 buy it now! Assuming you could collect (that's 3.6Mh/$ ROI)

Some people even manage to get them running over 300MHs potentially 4Mh/$ ROI @ $75

well, i've paid for my 3x7950 rig mining litecoin for a few months. all profit from here on out.
. ASIC's are slated to begin shipping very soon.
first they have to CREATE an fabric out of some 2nd hand manchines.. https://forums.butterflylabs.com/content.php/120-BFL-Invests-in-Assembly-Equipment
but ontopic, 5870 if bought 2nd hand are quick ROI get 400mhash out them, also 5970 are good to use but for now i d say waite untill december...or perpared to take loses if investing now....ASIC
with underclocking the ram, i was able to get my 6770 up to 960Mhz....getting about 210Mh/s out of it.
While risky, nothing will replace 5970's for ROI. If you look hard enough, you can find stable-ish ones for ~200 USD. I didn't do any math, because the actual ROI depends on your electricity rates.
With that said, the ROI is probably longer than the borrowed time most GPU's are running on. ASIC's are slated to begin shipping very soon.

shameless promotion....win 3x5970's for 1BTC:

Man, let me just withdraw a little bit from GLBSE. Oh wait.

BTCFPGA has FPGA's in stock, and they will offer a trade-in program to go from FPGA > ASIC. This might be your best bet to get in the game now, at low power usage, and trade-in the FPGA for full value on an ASIC. 6 months from now, mining will only make sense with ASICs.
unless a protocol change

I just ran the numbers and it looks like the 5870 is indeed the best bang for your buck. It could make around $50/mo approx and you can get a used one for just over $100 on ebay. That's not bad! The 5970 seems difficult to cool and even runs really hot stock and thus it's difficult to overclock so yeah it's fast but it's extremely expensive and you can't get it a whole lot higher necessarily.
5970, yeah look at my temps (video):

5870/5970 are in my opinion the best and they
Are cheap. (So Long there are no asics)
