I've always been a GeForce guy. When they were first competing, GeForce was the definitive favorite because of it's solid performance. I've just always stuck with them.
Same thing with AMD vs Intel. Always been an AMD guy.
Ya, same here. After 3dfx, I jumped into nVIDIA grudgingly. (was a 3dfx fanboi). But with the SOLID drivers, Linux support, active customer service and forums, I've found nVIDIA to be a good choice. The 2 times I strayed to ATI, I found myself with having to work with quirky drivers, misfunctional hardware, and lacking support.
eVGA is a great company as far as nVIDIA video card vendors are concerned. I've had issues with SLI from time to time, and they worked tirelessly with me to either fix the issue, upgrade the BIOS, or just RMA the cards for 1 step higher performance cards for no additional cost. You don't see that very often anymore.
