Random thought: Best GPU up to 75W capable of SLI/Crossfire

I was just wondering, but what is the best cards that support 2 way SLI/Crossfire that only uses 75W max/no PCI-E connector?

I've been interested in trying SLI/Crossfire out for a while now to get some experence with it & I was thinking considering how old such cards would possibly be that I might be able to get some sometime in the new year to experiment with.

The thought of entry level/low power cards came to me after seeing prices for 9-10 year old Radeon HD cards & it might be possible to get them for even less, here's some examples from local classifieds (I'm Canadian so prices are in Canadian):

(Unknown brand, Blue PCB so maybe Sapphire?)Radeon HD4350 512MB, was listed for $40 a week ago & was just listed again for $30.

 

OEM Dell Radeon HD4550 512MB DDR3, listed at $39 & more than 5 available pulled from working Dell machines, looking for offers.

 

while it uses more than 75W (requires 1 PCI-E 6 pin), it's cheaper than the lower end cards, a Sapphire Radeon HD5750 1GB GDDR5 for $20

That's about the extent of what you'll get.

 

Not a lot of better cards, even from that time period, will do Crossfire/SLI and not require any external power

If you want to Crossfire, the 560 is your best bet, among the 10 series only the 1070 and up can support SLI, and honestly you would be better of getting a better GPU rather than using Crossfire/SLI, those features are only best for high end GPUs, and for extending the life of aging hardware.
