thanx guys.. i also have a look on these GPU and got a good respond form the users especially ASUS direct CU2 and gigabyte with 3 fan.. i heard both of them are recommended from the tom's hardware itself.. but please give me the best among this 2 options as i can choose either one of them.. give the pros and cons so that i can evaluate it myself and make the best decision.. please..
best one out there is the msi twin frozr 4 670. then gigabyte (but barely under the msi).
msi has overvolting which does increase the oc capability. you dont necessarily need it but if you want to squeeze a bit more juice out of it, it will be there for you. overvolting too much will fry your card. the cooling solution is pretty much the best. gigabyte is on par with this cooling solution
gigabyte just has awesome temps. im running 50C at 1ghz using furmark
asus is overpriced. performs on par of a msi PE card but costs more and doesnt have overvolting. cooling solution isnt the best either
evga is completely overrated. their ftw cooler is only recommended in situations where im using a really cramped chasis
