Apple rolled out its new PowerMac lineup, what, a few months ago? If you absolutely do not need a PowerMac right at this minute, I'd say wait. I believe it's always better to buy immediately after speed bump or revision--that way, you know that you bough the best for your money for the next 6 months.
I've heard some people with PowerMacs having problem with WarCraft III when the battle gets hot and heavy, but the recent patches released by Blizzard might go a long way in fixing that. However, since Mac games are always made as an afterthought (the software companies go where their markets are), I'm of the opinion that performance of Mac games will always lag their PC counterparts. Thus, this is not even a hardware issue per se as much as how the games are developed.
Anyhow, if you do need a computer right away, by all means get one.
