Edit: I've found somewhere with that board in stock. Would it be worth upgrading with the 1260 instead? Or is that going to kill a lot of games?
Really... if you're going for the games, I'd NOT go for the 060.
There are some few newer games that are programmed to run fast on the 060, but many of them... (Napalm, Quake and some others) are way too demading to play well even on the 060. And, concerning the older games, they all (but moste of the 3D ones) will play just as fine on a 030.
Unless you are about to play MP3's, run some of the more demanding demos and toy around in Workbench (using a GFX-card) together with some GFX apps and other a bit power demanding applications, I can't not say that the huge difference in price between, say, a Blizzard 1230 and a Blizzard 1260 is worth it. Really.
