On a budget, another msi twin frozr iii gtx 660 oc in sli worth it? will it bottleneck my cpu(AMD FX6300), and will my PSU(THERMALTAKE TR2 600W) handle it?
 
Solution
Bottleneck essentially comes from the fact that the rate of pouring water out of a bottle is limited by how big the opening is. Or, the 'neck' of the bottle.

In your case, 2x 660's would be too powerful for you 6300 CPU, and thus your CPU would be the bottleneck. The performance is limited by how 'big the CPU whole is', or how effectively how powerful it is.

If I have helped, please consider choosing my answer as the solution. Thanks :)

It would be only worth it if you have dual monitors or if your monitor's resolution is higher than 1080p. If it is a single, 1080p monitor, then a single 660 is sufficient. Your CPU would bottleneck the card anyhow, while your PSU would be sufficient.

Makes sense. The whole bottleneck thing, i'm still trying to understand a bit more. So you're saying my CPU is too good for my GPU or the other way around....or is that even what "bottleneck" is?

Solution
getting a second 660 you may see a performance increase, however the increase seen will be limited by your cpu (bottleneck). If you get a more powerful cpu/or overclock your current cpu you will see more of a performance increase. Some games are more gpu dependant and some more cpu dependant, so it will also depend on the game. Something like skyrim you will probably see no improvement over a single 660 unless you upgrade cpu, while BF3 you should notice an increase as its more gpu limited., although i can run it on ultra 1080p with 60fps just fine with a single 660 anyway. What game are you trying to get more performance in? maybe that would help determine your best upgrade option. Also, be careful with thermaltake tr2's i have read reviews on particular models being bad, having excess ripple and noise when under 75% or more load.

one more question, would an AMD FX 8350 bottleneck with the 660 OC SLI?
