SOLVED Asus gtx 550 ti (top or dc)

I am looking at 2 video cards i have been waiting for the 1ed one to get in stock for about a week and a half but the other one is now 10$ off and i have a 10% off account specific coupon

from what i can see the hardware appears to be the same so could it be over clocked to the specs of the other version (i assume this would void the warranty) or is there some reason for the clock speed difference like the DC ones do not pass the requirements to be sold in the top series (is there a voltage difference) and more importantly is the performance difference noticeable

i know either one should be overkill for me since i don't too much gaming i am currently using a gt 430 which is much weaker

should i just go with the DC version considering the sale and the fact that the other is out of stock so much

Edit: noticed the dc version now has free shipping (was 7.56) at that price difference i will just go with the dc, still would like to know if i can clock it safely to the specs of the top version

It's the same card essentially, just grab the cheaper one.

The TOP is factory overclocked a little higher.
I have the DC, and using NVidia NTune, I've actually been able to clock my card up pretty high (1055MHz core, 2462MHz memory) with the stock DC heatsink/fan...
I'd say go for the DC, since it's cheaper, and can easily be OC'd to run a lot faster.
Hope this helps!
