I have two Nvidia Geforce GTS 250's with 1024 GDDR3 memory. I just got a free Geforce GTS 250 with 512 GDDR3 memory. The clocks are all the same its just the memory differnce. I was wandering if using coolbits I could use 3-way SLI? If that would work, is it worth taking the memory loss for 3-way SLI? Thanks.
