hmmm, let's see:
Voodoo2 SLI(I can't remember the brands, but it was a mis-matched SLI that worked flawlessly except in Half Life

)
Voodoo3 2000 PCI
Voodoo3 2000 AGP
Voodoo3 3000 PCI
Voodoo3 3000 AGP w/TV out(in a current system)
TNT2 (LeadTek)
TNT2 Ultra (LeadTek)
32MB GeForce DDR (LeadTek)
Voodoo5 5500 PCI(in a current system)
Voodoo5 5500 AGP
Radeon64 ViVo(in a current system)
. . .and it looks like I'm going to be one of those suckers who shells out the big bucks for a GF3

, too!  That way, when all the silly debates arise(and you know they will) about which card has better AA or 2D quality, I'll be truly qualified to respond

. . .just kidding

!  I want the burning frame rates

, especially at hi-res with AA.  Probably won't have to upgrade that system's vid-card again, either

.  Will I pay $549.99 retail pricing?  Hell no!  When was the last time any of you paid retail MSRP for a computer component?  Besides, I just want to have one; isn't that reason enough

? 
I know this looks like alot of $$$, but if you upgrade at the right time then you minimize the amount of $$ it costs to upgrade. . .and I 
always get a great deal!  I keep what works for me and dump the rest.  I must admit that for UT/HalfLife/NFS purposes, the V3 is simply the best deal out there, still!  I see them in the ForSale forum for $40 all the time.
