The 285 offers about 15% less performance than the gtx 550 Ti, it has about 100W higher power draw, and it doesn't support dx11. Currently you can buy an open box 550 Ti for $81 on newegg. I don't think you can get more than than about $60 for a 285. A quick check on ebay shows 285's going for about that (before fees are taken out). I probably wouldn't pay more than $30/ea if I were in the market for a budget card, a low end current gen card just seems like a much better option than an 3 generation old top end card. Similarly a mid priced current gen card would beat them in SLI at a much lower level of power/heat/fan noise and no SLI hassles.
