Mac or PC

Hey everyone,
So petGRO has decided to finally upgrade their hardware, in the attempt to gain some added value from newer tech.  More specifically petGro wishes to upgrade their desktop computers to either new Mac or PC models.  My recommendation is to go with PCs as they are cheaper and much more versatile.  Since these computers not being used for demanding purposes (such as 3D design), the best solution would be to have a PC that is fast and can multitask.  For this purpose, Intels i5 chip should be used in coordination with about 8 gigs of DDR3-1600 ram.  The desktop should also comprise of either AMD or nVidia mid-low range video card (depending on preference) and about a terabyte of memory (Solid State drives would allow for greater start up speeds and file transfers, but are expensive).  Sound cards and optical drives can be pretty much anything depending on how much money there is to spend and what purpose they will be used for.  In this situation it is probably best to go with a stock sound card and perhaps a bluray disk drive (who knows when they will be the norm ;) ) These components would offer a system that is fairly cheap, reliable, and perfect for the task at hand.  Of course if money is no option then we can have more fun, but I'll save that for another day.
Thanks for reading,
