I am running a Asus EN9600GT on a Asus P5N-E SLI. My question is: in terms of cash/performance ratio, should I get an additional 9600GT in SLI or simply by a new single card? 9600's are going for around 70, but then again I can spend an extra 30 or 40 and get a new card, but which will perform better?
A GTX 260 is probably roughly similar, the closest at the least.
Nvidia cards over $100 really aren't a good buy at the moment so if you are going to ditch the 9600GT I would recommend looking at ATI instead.
