First, what's a ramsink? And if I overclcokthe Asus to 4600 standards, won't that nullify the temperature benefits?
MSI GeForce4 Ti4600 $139 shipping. ~$8 @ compugeeks
Asus V8420S Ti4200 $146 free shipping @ newegg
MSI $147
Asus $146
Does this new information change your opinions at all?
Edit: Btw, how is the Asus V9280 Ti4200. Is it any good? it's only $100
