Radeon LE is not bad. It give you HydraVision (ATI term, of course) which basically allow you to hook two monitors to your comp. But Radeom LE doesn't have T&L engine. So I would go for Radeon LE for game and either flash its Bios or tweak it to get HyperZ enable. With Radeon LE (even without tweaking), you will get a really good graphic card (excellent image quality + fast), much better than GF2 MX in my opinion. Anyway, if you can find the Radeon 64 DDR VIVO pretty cheap (I would consider $199 (USD) a good price for it), you may love it for its functionalities.
I have tries many graphic cards and actually own couples of them currently (GF2MX variants, Radeon 32 SDRAM PCI, Radeon 64 DDR VIVO and etc.) and I have to say Radeon 64 DDR VIVO is the best graphic card I've used. I love the capability of capturing movies and output to my TV screen. DVD play back is also excellent on Radeon cards. Anyway, pick whatever you like and it will work best for you =)
