In about two weeks I am going to buy a graphics card for the new system I am building. I only want to spend around $200. Later down the road I would like to do the step up program to get an 8800GTX or newer gfx card. My question is if I get a zalman aftermarket cooler for the graphics card will that void the warranty/eligibility for the step up program? Also, do any other manufacturers do a program like this? I tend to like XFX and BFG more than EVGA.
