Oh $40 Canadian. Yeah, then it probably is. How much would you be paying for them? The 128MB will definitely help out in future games. More compex textures and so forth. It also helps out with AA and aniso to an extent. I just got a ATi R8500LE 128MB retail 2 days ago for $249. Works great so far, not to be disappointed. At least doubled my score in both 3D Mark2K1 SE and GLExess, although I'm running a P4 1.4GHz. I'll do some tweaking and try and get it even faster!!
Also have you looked at a GF4 Ti4200. They are a bit faster than the R8500, although they're a bit costlier too.
What's the deal with lampshades, I mean it's a lamp, why would you want a shade?
