Gateway M505XL VS Inspiron 8600 -

Both have 1.5GHZ, 512MB DDR, DVDRW, 60GB.

$1800 VS $2000.

Dell pros: WSXGA+, 128MB pro turbo, 7200RPM HD.
Gateway pros: $200 less, subwoofer, extra USB (not important), SD reader (not important), might can get before Christmas (can anyone confirm this?)

What do you think? It'd be nice to save $200 and open it on Christmas, but the Dell is a better machine. Will I notice the difference between the VCs? If I could get a 15% off coupon for the Dell I'd definitely buy that, maybe with a 1.7GHZ if I could afford it.
