Hi, I have been using my Twin Frozr II 560 Ti for a year and a half, and have been happy with the performance. Now I can find used 560 Ti on ebay for less than £100, so I was thinking of SLI'ing.
On the other hand, I plan to upgrade to Haswell later this year , so I can forget the SLI, save the £100 towards a future GPU along with Haswell, possibly Titan/GTX 770?
Another point being that 560 Ti only has 1 GB memory, so I don't see this SLI setup being future proof, so I am better of buying a single GPU later on along with the CPU upgrade. Opinions?
