Thanks Scataphagos.
What I don't understand is why Dell T5500 with a cheap Processor & motherboard & HDD is twice as expensive compared to XPS 8300.
One reason... T5500 is a workstation... with [supposedly] server-class components.
XPS is an overpriced, rather low-end "consumer class/gamer" line which is marketed as something better than it really is.
When you get into multi-video card rigs, the mobo becomes a high consideration. Workstation computers are designed to run "multiple this-and-that", while the XPS is basically a gamer computer designed to run one video card.
Also, Dell is notorious for high mark-up on computers with higher-end components and add-ons. Dell has both terrific values on some machines and a real hose-job on some others. It pays to know which is which.
