how do you find that out? I bought my MR9800 two mounth's ago.

I'm bored the now, so looked it up.
Thermal conductivity, measured in Watts per meter per kelvin (W M^-1 K^-1)
So yeah Silver is the best, Magnesium is better than copper, but a bit risky, maybe not though.
Now assuming you use (forgive me here for the sizes) 6 x 1cm^2 x .05 cm^2 + 1x 9cm^2 x 0.15cm^2. Total volume = 1.65x10^-6 m^3
Total mass of Copper: 0.0147345 Kg
Total mass of Silver: 0.017325 Kg (117.6% of copper mass)
Now ive used a few sites here and done some calculations so iff these figures are wrong, i dont care.
Cost per Kg of Copper = $3.4 USD
Cost per Kg of Silver = $237 USD
Cost of Copper for heat mod: $0.05 USD
Cost of Silver for heat mod: $4.11 USD
Ok so it looks like it shouldnt cost you more for Silver, but these are cost prices of the meatals, I recon you ended up paying about $5 for the copper? If you can expect the same mark up (which is probably unreasonable) but it would cost you ~$400? (its not really gonna be that but think about, you might still end up spending +$50? and where you gonna get sheet silver from?
So for the benifit for an extra few points in the thermal conductivity its not going to be worth it.
This is all a bit stupid and I may seem like a **** for doing it, but i'm a bored Engineering student trying not to study, so its been fun But my point in, why come on here shouting "why use copper silver is better" its pointless, the guy has went to the bother to show us what he got using silver, if you want to do it better, go for it.
Well in Tom.
ps. i can take pics of these thermal figures if you reeaaaalllly want, or if anyone else wants some other figures for fun too
