Hi All,
I did not want to spend a bunch of money, given how little time I actually spend gaming. I picked up a second GTX 660 (GTX660-DC2O-2GD5) for SLI on eBay for $100 and I'm pretty thrilled the upgrade! So far I have tested BF3, Bioshock Infinite, Borderlands 2, Portal 1/2 and things all look and play great.
Here are some numbers to compare.
