you can have 1 mac card for osx and 1 pc card for windows. all you have to do is to switch the cable upon reboot.
a mac booting windows is a PC.

If you have a Dell monitor that has VGA & DVi inputs then no need to switch cables, just select the input via the front panel buttons.

I was in the same quandary that you are in. I had one PC for gaming and a mini mac for everything else. The mini was underpowered for photo editing and such, so I had the choice of either a PC for games, plus an IMac for everything else or just get a Pro to do it all. I didn't like the idea of two machines with rats nests of cables, cables switch boxes and such. So I got the Pro with a 4870 and am glad I did. In the future when the 4870 fails. I'll get a lower powered card for OSX and an off the shelf PC video card for gaming in windows.

I used to be a PC fanatic, always updating to the latest cards, faster ram, etc. But in all honesty the changes you see from generation to generation of card, processor are best described as incremental. Yes they may quote that you get 20Fps more, but does it really make a great difference above 60FPs? I don't think so.

Or get a 2 port KVM switch for convenience for those "Ugh. I have to stretch to reach the cables..." moments. ;) :D :p

That's a great suggestion.
You've got me looking at KVM switches.
I've found two problems:
Very few support 30 inch monitor resolutions.
Those that do are quite expensive.
 
the 4890 works just fine. btw the new mac i just bought is off the hook.. i just love it so much
 
something i want :D

* 2.8GHz Intel Core 2 Extreme
* 2GB memory
* 500GB hard drive1
* 8x double-layer SuperDrive
* ATI Radeon HD 2600 PRO with 256MB memory

The new imac
 
Yep, I found them, thank you.
The reviews on the Belkin are a little iffy.

It will be nice to run a powerful PC card without unplugging the monitor cables.
I didn't read the reviews, so I don't know the details about the Belkin unit.

As I also didn't know where you're located (US, Europe,... ?), the link was just for information (model #'s to check other sites for example). Newegg's fairly easy to find things, but for other sites, it may be harder to narrow the search parameters.
