as i said 3800 series is about the same price range that outperforms the 4670...and i mean 3800 series meaning both 3850 and 3870 outperform the 4670....as for the 3850...the 256mb version edges out the 4670 by a hair...but remind you 512mb version ranges anywhere between $60-70 depending on where you buy it...and 3870 is on another level from 4670....for only about $10 difference...
and yes...i said it b4...i said if you want to spend a bit MORE then go for 4800 series...but bottom line is...4600 series are not worth the money...neither is the 4800 series at the moment imo but if you want top of line...then be my guest...
3800 series are probably your best bang for the bucks atm...
Edit: found a 3870 cheaper than 4670 $85
