It's $41.13 more for the comparable eVGA piece from Newegg with shipping, albeit getting it faster. Plus you'll be able to Step-Up when the next big thing comes out.
My problem is that I'm not certain to be building a new rig within 3 months, so I'd rather save the $40 now and then survey the landscape when I'm really gung-ho to build a new rig. By the time Crysis or some other DX10 needing title drops, quad-cores and 89-series cards will be out and Vista may be getting ready for prime time along with drivers, etc. My rig is fine for now for most games, so why rush? In September, faster, cheaper stuff will be available. Good things come to those who wait.
