Objects like to fade off once you back away from it further then somewhere around 5-30ft depending on the object. This is especially a nuisance in Garry's mod. But there was a mod for Gmod that improved visuals and fixed the fade away problem.
I think it's not a bad idea to get a high-end GPU now. I mainly think this because it will play games fine on high settings for enough time to see both the G80 and the R600. Then if the R600 ends up being better then the G80 you wouldn't spent 500+ dollars on a G80. Also it gives time to hear anything about a "8900 GTX or X2900 XTX" or someother improved version of the card. Then if you can sell your card (depending on your selling skills) you can shave off the cost for the card. Right now you can get a retail Sapphire X1900 XT for $420 dollars off newegg ($450 - $30 mail in rebate).
Also keep in mind about PPUs which enter the market soon (actually they've already did but you have to spend a crap load of money to get a Alienware, Dell XPS, or Falcon computers that has one equiped).
The first DX10 capable game/engine will be Crysis (crytek engine) and at an interview on computerandvideogames.com the devs said it will release Winter 2006; and all the pics/footage you've seen of the game are all in DX9 hardware and on a singlecore CPU (the engine does have multi-threading so if you have dualcore you will see improvment).
