My computer in its current configuration consists of an AMD FX-8350 and an Nvidia GeForce GTX 770 SC. I kind of want to purchase another GTX 770 so that I can have two in SLI. Due to the increased power draw this would introduce, I would need to purchase a new PSU with a higher wattage (my current PSU is a 750- watt) Should I upgrade to a dual GTX 770 SLI configuration, or just wait a couple of generations for the next, reasonably priced graphics card? I cannot afford to buy GTX 780TI's and TItan level cards. Thoughts?
Depending on the specifics of your PSU and the rest of your rig, I believe it would be up to the task of handling 770's in SLI, so upgrading the PSU may not be necessary. If you're hurting for more performance, SLI is not a bad route to go. However, Maxwell looks very promising, and so does the successor, so if you can live with a single superclocked 770, I'd wait. I know my 760 ACX SC is keeping very happy, and the only thing I can throw at it that allows it to flex it's muscle is heavily modded Skyrim (granted I'm not playing Metro or Bioshock Infinite (waiting to complete the first two)), but I'm pretty sure I'm actually CPU bottlenecked (running stock-clock 2500k; ambient temperatures fluctuate too much for heavly OC) in skyrim since utilization never goes above 80% @1202MHz on my GPU, and usually hovers around 60% or so.
