ubuntu 14.04.1 linuxcnc help

Previously promised link. Im wanting to use this computer due to lack of funds and its actually a pretty solid build for a laptop.
I was contemplating spending $25 dollars to upgrade the cpu to a t9300, which should reduce heat output of the cpu, and be a little bit safer to run smictrl.
I have copper sheet, i think would be useful for added heat displacement. A peice over the cpu, and a peice over the gpu, should help a lot plus the cooler cpu. ( for $25 outta pocket this is a good move, i think.)
does anyone feel the cpu change would hurt latency? Its a boost in cpu power by .3 plus much lower heat.
Plus i have some ddr3 2x4gb ram that may work. it cant hurt on a trial run.
all things on hand, minus the paste and cpu, this shouldnt set me back much.
One thing i was waiting on buying was the breakout board. consider my output will be about 3.5v, is there a breakout board that anyone would suggest?
thanks in advance,
jason

What type of breakout board are you thinking of? When I think of breakout board it requires a parallel port connection which your laptop doesn't have.

or unconventional requires some understanding of arduino and python and is a little slow uses USB

the above web site is a mess to navigate on

My plans are to use a pcmcia adapter parrallel port. or if it will allow for better latency there is a docking station available for this laptop for cheap, which will also allow me to not use the onboard graphics chip, saving me a small amount of latency by reducing shared memory between the gpu and ram. both of which has worked for other users, albeit documentation is fleeting and limited to audio recording use.
Additionally the computer has vga output and a serial - RS-232 - 9 pin D-Sub (DB-9).
Im undecided. and in need of a better education on how linuxcnc reacts with each.

There was a grbl based board i was partially interested in. the tinyg 2. the motion control for it is said to be much better than other usb grbl controllers.
I wasnt much interested in usbbased controllers but if i was this would be my choice.

I suppose if there was a problem with the output votage of the laptop and the breakout board i could always boost it using darlington transistors. they would add a tiny bit off latency as well though.
Im also iterested in controlling four to five axis robotic arms, and was curious to hear others use linuxcnc for this as well. being in the robotics trade, could you point me towards websites geared for this particular use?

I own this and plan to use it in my build

Also as a note I do believe grbl board will not work with linuxcnc only grbl software
