Well...
- I have 2 ATI cards in my known technology collection (amongst about 7-10 nVidias, about 6 of which are capable of mining - at 2-5 Mhash/sec).
-- One of which is the 6770 that I use for mining 24/7.
-- The other is a 3700, if I remember correctly.
- I'd really like some freedom to play with other pools.
- I've only ever made a grand total of about 0.6 Bitcoin in the entire ~3 weeks of 24/7 mining on the 6770.
-- Low, low price of 5 BTC my ass?

I think it'd take an eternity to mine that back...
If the miner goes faster on the 3700, than the ~20 Mhash/sec that my horrifyingly over-powered (and now blown-out, evidently) 8800GTS produces, I'd love to play around with it... even if it's stupidly inefficient, you'd really just need to step back and look at how bad nVidias are that people still try to mine with
