My Laptop has a built-in graphics card of 1.7 GB with 2.3 GHz CPU speed. Is it enough for mining at a decent speed?

easy answer no!
longer answer - what GPU is it ? and no probably not

mining with a laptop is generally not a good idea no matter what gpu it has, due to heat generation.
nevertheless, to determine your gpu under windows 7, right-click anywhere on your desktop, left-click 'screen resolution', left-click 'advanced settings', and left-click the adapter tab. if your machine has an ati/amd radeon hd 5xxx+ gpu, you might consider mining. if you do end up mining, be sure to cool the laptop with an external standing fan or some such, as your laptop will get very very hot.

Lol at people who measure their graphic card by the memory  :D so if it has 4gb it is better?  :o

Marketing ... it works.

Yeah  :-\ Laptop with 2gb graphic card  :o :o

Should be an Intel HD Graphics family CPU with integrated GPU. It basically re-uses free system RAM as graphics RAM, which is how it arrives at that weird huge number.

It's also totally and completely unsuited to mining.

Yeah, that system is fail, the delay of using normal ram as GPU ram means that the idea is fail.

I don't wanna burn my computer  :o

Thanks guys!

Substrata, are you going to replace his laptop, after he has turned it into a brick of coal by running it at 100% all day every day?

Hmm.... I would certainly like to try that using my laptop, but as greyhawk said, no one will replace my laptop if, my cpu gets overheated. :)

So, I'd better get a graphics card for my PC and would try on it later!

Definitely. Though GPU mining will be a thing of the past in about 1 month, if the ASICs turn out not to be vaporware.

Does it depend on the CPU speed and its processing bits? Coz, my PC is an old one (32 bit CPU and 32 bit motherboard). Does it limit the GPU functionality and the mining speed? :P

No.

Anyway, as other said, in the next months ASIC will be released. And then GPU mining will become useless

Look into getting an fpga or ASIC product for mining.

Only ASIC!
FPGA mining, like GPU, will be totally useless  :)

The OP clearly was concerned about profitability as expressed in his very second sentence


He further proposed buying a new graphics card for the express purpose of mining on an old secondary PC.

I am not going to go ahead and advice OP to "yeah sure, you just do that" and have him either reduce the lifespan of
his laptop significantly or spend an absurd amount that he has no chance to ever regain in the current mining
environment, just for some obscure 5 minute learning experience (which is as long as it took me to set up my miner
and it only took that long because the first particular download was corrupt) .
