Ya, but SLI is part of the PC

What I'm saying is that my PC is still managing to stand with the big boys even 18months after purchase. In order for that to happen, a PC must have a solid foundation. Cost effective additions are helping.
So while I may not be the fastest, and indeed, I'll continue to slowly lag towards the back of the pack, for the moment, my grandaddy of a PC is holding it's own.
