Welcome to Gaia! ::

Super name: Silver Surfer
Real name: Norrin Radd
Strength: Vast Superhuman Strength. The Silver Surfer can augment the strength of his cosmic energy-powered body to a degree that rivals the Hulk's formidable rage-enhanced strength. Hence, he can endow himself with Class 100 strength, enabling him to lift (press) well over 100 tons.
Speed: The fastest he has ever gone was 14 times the speed of light. He doesn't usually do this unless he was in a big hurry. He usually only moves at 3-4 times the speed of light when he is exploring.
Durability/Endurance: I really don't know if he can be destroyed. there was an issue of silver surfer where someone had strapped an energy sucking device that was sucking the universe's energy into Silver Surfer. When it overloaded and exploded everyone thought Silver surfer was a goner along with the few galaxies he was presently around. Silver Surfer survived but was completely out of energy and could barely move. There is an issue of SS where, during the infinity crusade, Thanos goads SS to turn himself into a living bomb. The force of the explosion nearly kills him... it vaporizes the planet, as well... He ends up in a limbo-like place, where he meets his parents.
Intellect: The Surfer is a fairly smart character. Being from a humanoid planet that was made up of nothing but scientists, The Silver Surfer usually knows his stuff when it comes to gadgets and how to work them.
Fighting Skill: Average hand to hand fighting that is used along with his power cosmic.
Techniques/Powers: The Silver Surfer possesses vast cosmic power granted him by Galactus as a part of the process of physically restructuring the Surfer's former organic body. He has the ability to channel ambient cosmic energy into his body at will, and expel it violently as concussive force or gently as a means to restructure molecules according to his mental design. He can generate beams of energy through his hands with sufficient destructive force to level a large city or generate such subtle amounts of energy to restructure the molecules of the natural dyes within a plant to change its color. The Surfer can rearrange the molecules of matter to create other configurations, but he cannot transmute elements.
The forces binding together the molecules making up the silvery material that comprises the Silver Surfer's "skin" are so great that there are few known forces in the universe great enough to overcome them. The inner portions of his body have also been made highly resistant to injury. Thus the Surfer is invulnerable to most forms of physical harm.
He can withstand great extremes of temperature caused by the build-up of friction within atmospheres or the vacuum of space or (within limits) the intense heat within the near vicinity of stars. He can survive without difficulties in the vacuum of outer space and hyperspace, and his body can withstand the stresses of travel at near-light speeds in this universe and of even greater speeds, in hyperspace.
The Silver Surfer has certain cosmic energy enhanced perceptions which enable him through concentration to become aware of the patterns of energy which surround him. Accordingly, he can sense great concentrations or deployment of energy anywhere in the world. He has a special affinity for the life energies of living beings, and can use his cosmic powers to augment them to a certain degree. While he can use his power to revitalize life energies and heal the wounded, he cannot create life or restore life to the dead.
The Silver Surfer does not need to eat or breathe since he absorbs life-maintaining cosmic energy direct through his skin. Although his body does not require sleep, his mind still does in order to give it an opportunity to dream.
By exceeding 99% of the speed of light (186,000 miles per second), the Surfer can shift himself into hyperspace, a dimension in which velocity is not limited by the speed of light. The Surfer can also compress his own bodily matter so as to shift himself into a so-called microverse. He once used his powers to travel through time, but may be unable to engage in time travel under normal circumstances
Gear: Transportation: In flying the Silver Surfer usually makes use of an object known on Earth as his "surfboard", due to it's resemblance of Earth objects of that name. The Surfer's "surfboard" is a construct of unknown materials created by the vast cosmic energies of his former master Galactus. The board is covered with the same silvery glaze that the Surfer's body is covered with, making it impervious to virtually all forms of physical damage. Few forces short of the cosmic power of Galactus could affect it at all.
The surfboard is psionically linked in an unknown way with the Surfer's mind. Apparently only a being possessing the Surfer's cosmic powers can cause the surfboard to fly, and it is controlled mentally by him. The surfboard apparently taps ambient cosmic energy in much the same way that the Surfer himself does. Although the Surfer could conceivably utilize his cosmic power to fly without it, the surfboard enables him to fly without the expenditure of any of his own energy.
The Silver Surfer can utilize the surfboard to attain 99% of the speed of light, but seldom exceeds Mach 10 (ten times the speed of sound) within the outer layers of a planet's atmosphere, and Mach 5 within the inner layers. (The speed of sound is about 770 miles per hour).

Done.

I'd concede to that as well if we could actually get some numbers as to what he's capable of these days.

That's not true about his speed.

In Infinity Gauntlet, he went 1 light-year in 1 second, to try to grab the Gauntlet from Thanos.

That calculates to over 31 million times the speed of light.

In the Anhilation Wave books he was able to destroy a planet with out aid from Galactus. It is also assumed in those books that Galactus also made him more powerful as well. At this point we can not assume any upper limits in power as the new and improved Surfer does not seem to have them.

Last I check, the Surfer is now once again
the current Herald of Galactus.

As for endurance/durability. The only real
limit I can gather from marveldatabaseproject.com
is that the Surfer does require sleep, though
not nearly as often as humans do, needless
to say.
