I own a 250GB 360, 320GB PS3 and a good gaming rig. I have a 40" 1080p Samsung for the consoles. (Saving for a 7.1 surround system.)
My gaming rig consists of:
MSI Big Bang Xpower
I7 950 @ 4.2GHZ
Crossfired 5870's
6GB @ 1600MHz 7-8-7-20
X-Fi Titanium sound card
5.1 speakers (6.1 really but I just use 5.1.)
24" BenQ @ 1920x1200
80GB Intel X25-M SSD

Some games I refuse to play on anything but PC. (FPSers/TES/Fallout series.) Others I prefer on the console for simplicities sake. (Platformers)
It gets cold up here in the winter. (Unfinished attic with nothing but bleed through heat from downstairs.) I find I play more console games during the winter because I can sit under my 3 blankets in my bed. I do have one for when I am sitting at the PC but it's not as comfy. (And I hate when my blankie gets all caught up in the chair wheels trapping me.
)
