Would look cool in a clear plastic case or one with a window. Are those about like a 8800gt?
No, they are 9600GT level. Assuming you get a GDDR5 version of course.
Well it's not pointless, true, but it has a small market. 9800GT costs the same or less, and is faster. If you are interested in HTPC, 4670 costs quite a bit less. But I guess if you want faster performance than the 4670 but still want super low power it's good. I agree they will be much more attractive at $80 - truly a 4670 killer.
Mainly the GT 220 is pointless.
