Topic says it all. I've got a Gigabyte DS3 motherboard, which is great. But I'm thinking of picking up a used 8800GT for less than $100 and doing some SLI. Only problem is I don't have an SLI mobo. I hear bad things about the 780i chipset from Nvidia. Is it all overblown? I'll be running Vista 32bit, maybe 64bit in the future.
What are suggestions for an SLI motherboard? Would it be a better idea to just get a beefier gfx card, like one of those x2 ones? That's probably more expensive though.
Currently I'm running a 3ghz core 2 duo (E8300) on air with a Corsair 520 watt PSU.
