You have no need of actually calculating something serious?

Some sort of 2 core chip without ecc RAM and without low latency  
infiniband network
that is enough for your calculations?

Usually such cards are a $100 or so a piece. then add chip costs. i3  
is right now.

http://ark.intel.com/products/50177/Intel-Core-i3-560-Processor-(4M- 
Cache-3_33-GHz)

$117-$138 introduction price for 3.3Ghz dual core chip.

And it's TDP 73 watt. Add mainboard. Probably at full load
we're looking at 150 watt or so.

So best case you're looking at a $250 pricerange, or $125 a core,
without network yet and without RAM and 75 watt a core.

Isn't that a tad expensive?

My nodes here, network not counted, were $25 a core (2.5Ghz Xeon  
L5420, they're under $30 on ebay now)
and total box including Mellanox QDR card eats 170 watt from the  
power tap
at full load (100 watt idle but that's not a relevant measure in HPC,  
much as opposed
to server farms) so that's 21 watt a core.
