Having just jumped off my latest stint on the upgrade treadmill, I can't help but roll my eyes at the latest development in game tech. This time: hooking two PCI-Express graphics cards together and running them parallel. PC game old-timers will remember a similar solution from Voodoo at the dawn of 3D gaming (what, 1998?) It was expensive then, no doubt it will be expensive today. The potential for inspiring computer-geek-penis-envy is as yet unknown.
