Thanks for the advice everyone
I believe I will go with the 660 Ti first.
Do any of you know which manufacturer seems to be best?
From what I have read, this MSI 660 Ti
appears to be a good mix of stability/low temps/quiet. So far, it looks like the one I will be purchasing in 2 days (fri, sept. 5th), unless I can be persuaded otherwise.
@regor245 and whoever else may have been confused about my budget range I apologise, I should have made it clear that I meant ~$300 each
. Thought I fixed that before I posted
