I currently have a 560 TI 448 in my rig, and I'm looking to upgrade. I was wondering if 2 650 GTX cards in SLI would be better or worse than 1 660 TI GTX. Cards are on sale and I can get the two 650's for less than the one 660 TI.
Also, I would be looking to WC these blocks, so if anyone has any experience with these cards it would be helpful to know how hot/loud they get without waterblocks on them, because buying 2 FC blocks would ruin savings I get.
You could try to get another 560ti, as the 650 apparently can't be set up in SLI. Or go with a single gtx660ti, that way you avoid potential problems such as microstutter, driver issues, or scaling issues that can be present in certain games when running in a multiple GPU setup. Also I doubt that they make waterblocks for the 650, and for the price of the waterblocks themselves I would simply get a better, non reference card (custom cooler).
